Abstract
Agrobacterium tumefaciens infects and causes crown galls in dicot plants by
transferring T-DNA from the Ti plasmid to the host plant via a type IV secretion
system (T4SS). This process requires appropriate environmental conditions, certain
plant secretions and bacterial regulators. In our previous work, a member of the LysR
family of transcriptional regulators (LsrB) in Sinorhizobium meliloti was found to
modulate its symbiotic interactions with the host plant alfalfa. However, the function
of its homologue in A. tumefaciens remains unclear. In this study, we show that the
LsrB protein of A. tumefaciens is required for efficient transformation of host plants.
An lsrB deletion mutant of A. tumefaciens exhibits a number of defects, including in
succinoglycan production, attachment, and resistance to oxidative stress and iron
limitation. RNA-sequencing analysis indicated that 465 genes were significantly
differentially expressed (upregulation of 162 genes and downregulation of 303 genes)
in the mutant compared to the wild-type strain, including those involved in
succinoglycan production, iron transporter and detoxification enzymes for oxidative
stress. Moreover, expression of the lsrB gene from S. meliloti, Brucella abortus or A.
tumefaciens rescued the defects observed in the S. meliloti or A. tumefaciens lsrB
deletion mutant. Our findings suggest that a conserved mechanism of LsrB function
exists in symbiotic and pathogenic bacteria of the family Rhizobiaceae.
Introduction
Agrobacterium tumefaciens is a facultative plant pathogen that induces crown gall
diseases in dicot plants. During infection, a DNA fragment (T-DNA) from the A.
tumefaciens Ti plasmid is transferred to plant cells and integrates into the plant
genome; the transgene-encoded proteins drive the synthesis of phytohormones,
cytokinins and auxin, which elicit plant cell proliferation and tumourigenesis (White
and Braun, 1941; Thomashow et al., 1984). This process requires the VirB/D4 type IV

secretion system (T4SS) of A. tumefaciens. Because of its ability to transfer DNA to
plants, A. tumefaciens has been developed as an important tool in plant genetic
transformation and engineering (Azpiroz-Leehan and Feldmann, 1997).
The virulence (vir) gene located on the Ti plasmid is essential for T-DNA transfer and
tumorigenesis. A. tumefaciens possesses a VirA/VirG two-component regulatory
system that senses important environmental signals, including acidity,
monosaccharides, and phenolic compounds such as acetosyringone (AS), which are
released by wounded plant cells, to regulate vir gene induction (Shimoda et al., 1990;
Palmer et al., 2004; Brencic and Winans, 2005; Bhattacharya et al., 2010; Pitzschke
and Hirt, 2010; Lacroix and Citovsky, 2013). Plants generate high levels of reactive
oxygen species (ROS), such as H2O2 and superoxide radicals, which are employed in
an important initial defence mechanism to inhibit bacterial invasion and proliferation
(Baker and Orlandi, 1995). Catalase (CAT) and superoxide dismutase (SOD) are
crucial antioxidant enzymes that degrade H2O2 and superoxides, respectively. These
enzymes have been shown to serve as virulence factors involved in A. tumefaciens
tumorigenesis (Xu and Pan, 2000; Saenkham et al., 2007). Iron ions are also key
players in maintaining redox homeostasis in bacteria. Homologous iron-sensing
regulatory ferric uptake regulation (fur) genes from plant pathogens have been shown
to play a critical role during plant-pathogen interaction (Franza et al., 1999;
Subramoni and Sonti, 2005). In addition, plant mechanisms for depriving invading
microbes of iron have been suggested (Neema et al., 1993). Therefore, plant
pathogens need to overcome both oxidative stress and iron deprivation for survival
and proliferation in host plants. The A. tumefaciens catalase KatA is an important
virulence factor involved in the detoxification of H2O2 released from plant tumours
(Xu and Pan, 2000; Xu et al., 2001). Expression of katA in A. tumefaciens is regulated
by OxyR, a LysR family transcriptional regulator that is responsible for bacterial
resistance to oxidative stress (Nakjarung et al., 2003). A. tumefaciens, B. abortus and
S. meliloti are members of Rhizobiaceae family and these are conserved in a much
larger family, such as OxyR/KatA homologues (Jamet et al., 2005).

In our previous work, a new LysR family transcriptional regulator gene, lsrB, required
for nodulation and nitrogen fixation (Luo et al, 2005) was identified in Sinorhizobium
meliloti. A lsrB deletion mutant induced the formation of inefficient nitrogen-fixing
root nodules on host alfalfa plants (Medicago sativa) (Tang et al., 2013). As LsrB
directly regulates the expression of genes involved in lipopolysaccharide biosynthesis
and glutathione production (Lu et al., 2013; Tang et al., 2014), it constitutes a new
redox regulator in S. meliloti (Tang et al. 2017). A homologue of lsrB has also been
identified in Brucella species (Foulongne et al., 2000; Sheehan et al., 2015). However,
the function of LsrB in A. tumefaciens has not yet been determined.
In this work, we constructed an A. tumefaciens lsrB deletion mutant and examined it
for both free-living and pathogenic phenotypes. We identified new functions of LsrB
in A. tumefaciens and also compared the functions and mechanisms of three LsrB
proteins from B. abortus, S. meliloti and A. tumefaciens. A conserved mechanism of
LsrB in all three species is proposed.
Results
Expression of the pathogenic bacterial lsrB gene rescued the symbiotic defects of
the S. meliloti lsrB mutant.
Homologous lsrB genes have been identified in several bacterial species, including
members of Sinorhizobium and Brucella (Tang et al., 2013; Sheehan et al., 2015). The
LsrB proteins from A. tumefaciens and B. abortus share 88% and 69% identity with
the S. meliloti LsrB protein, respectively. These proteins are composed of a
DNA-binding domain and a LysR substrate-binding domain (Fig. 1A and Fig. S1),
and the observed protein sequence identity suggests that they may share the same
function or mechanism of action.
To assess this possibility, the S. meliloti lsrB deletion (∆lsrB) mutant, which induces
defective nitrogen-fixation nodules on alfalfa, was used in a symbiotic nodulation
assay with alfalfa plants (Tang et al., 2013). In Rhizobium-legume symbiosis, mutants
that induce less effective nitrogen -fixation nodules can induce the production of a
larger number of the plant organs (Oka-Kira and Kawaguchi, 2006). The lsrB gene
from A. tumefaciens or B. abortus was expressed in the S. meliloti ∆lsrB mutant, and

each strain was inoculated onto alfalfa seedlings. After four weeks, the growth of
plants inoculated with the lsrB deletion mutant expressing the lsrB gene from either A.
tumefaciens or B. abortus was similar to that of plants inoculated with the wild-type
strain of S. meliloti (Rm1021) (Fig. 1B). Additionally, the biomass (dry weight) and
number of nodules of plants induced by the mutant expressing lsrBat or lsrBba were
found to be similar to those induced by Rm1021 (Fig. 1C-D). These results indicate
that the lsrB gene from A. tumefaciens or B. abortus completely rescued the symbiotic
defects of the S. meliloti lsrB deletion mutant, suggesting that these LsrB proteins
have conserved physiological functions or molecular mechanisms in both symbiotic
and pathogenic bacteria.
The A. tumefaciens ∆lsrB mutant is deficient in host plant transformation.
To determine new functions of the lsrB gene during interactions with hosts, an A.
tumefaciens lsrB deletion mutant was constructed using a suicide-plasmid
homologous recombination method (see Materials and Methods). For the
complementation analysis, a plasmid expressing the lsrB gene from A. tumefaciens, B.
abortus or S. meliloti was introduced into the ∆lsrB mutant. In addition, a
plant-expression vector pCAMBIA2301 (Cambia, Canberra, Australia) carrying a
CAMV-35S driven-GUS gene was transferred into each A. tumefaciens strain for the
plant transformation assay. Roots of young Arabidopsis seedlings were treated with
each strain, and β-glucuronidase (GUS) activity in wounds was determined. The
results showed that the lsrB deletion mutant induced fewer (less than 1/10 as many)
transformation events than the parent strain C58 C1, whereas the plasmid expressing
the lsrB gene from A. tumefaciens, B. abortus or S. meliloti completely rescued the
defect of the mutant (Fig. 2A-F). These results suggest that LsrB is required for A.
tumefaciens transformation of host plants.
The lsrB gene is required for efficient attachment of A. tumefaciens onto host
plants.
As bacterial attachment is a key step in the infection of a host plant by A. tumefaciens
(Lippincott and Lippincott, 1969), we therefore evaluated the attachment efficiency of
the A. tumefaciens lsrB deletion mutant onto Arabidopsis roots. Roots were soaked in

fresh cell suspensions of A. tumefaciens constitutively expressing green fluorescent
protein (GFP), and attached cells were analysed under a fluorescence microscope after
two hours. Compared to Arabidopsis roots inoculated with the parent strain C58C1,
weaker fluorescence intensity was observed in the Arabidopsis roots inoculated with
the lsrB deletion mutant (Fig. 3A-B). This defect was rescued by expressing the lsrB
gene from A. tumefaciens, B. abortus or S. meliloti (Fig. 3C-E). The numbers of
bacterial cells attached to the plant roots were counted by diluting and plating samples;
significantly fewer cells of the lsrB deletion strain were present compared to the
parent strain C58C1, and higher counts were observed after introducing the lsrB gene
from any of the three bacterial species (Fig. 3F). These results suggest that LsrB is a
positive regulator of Agrobacterium attachment onto host plants.
The LsrB protein positively regulates succinoglycan and biofilm production in A.
tumefaciens.
The A. tumefaciens lsrB deletion mutant grew slightly slower in liquid medium
compared with the parent strain C58C1, and this defect was rescued by the expression
of the lsrB gene from A. tumefaciens, B. abortus or S. meliloti (Fig. S2). Interestingly,
the colonies of the lsrB deletion mutant did not appear mucoid, which prompted us to
evaluate exopolysaccharide (EPS, succinoglycan) production by the mutant. The
fluorescent stain Calcofluor White M2R, which can specifically bind to succinoglycan,
was used to evaluate succinoglycan production by A. tumefaciens, showing that the
colonies of the lsrB deletion mutant produced weaker fluorescence than did the
wild-type strain (Fig. 4A). The introduction of plasmids expressing the lsrB genes
from A. tumefaciens, B. abortus or S. meliloti restored succinoglycan production in
the lsrB deletion mutant (Fig. 4A). Quantitative analysis of the fluorescence intensity
revealed that 5-fold more succinoglycan was produced by the parent and
complemented strain compared to the lsrB deletion mutant (Fig. 4B). The total sugar
content in the exopolysaccharide produced by A. tumefaciens growing in broth was
analysed using an anthrone sulphuric acid method, and the results revealed
significantly decreased total sugar for the lsrB mutant compared with the parent or
complemented strain (Fig. 4C). Additionally, biofilm formation by each A.

tumefaciens strain in tubes was examined. Based on visual inspection, the lsrB mutant
formed only a small amount of biofilm, whereas the parent and complemented strains
produced a large amount of biofilm. Furthermore, quantification of the biofilm using
crystal violet showed less biofilm on tubes formed by the lsrB deletion mutant
compared to the parent or complemented strain (Fig. 4D). These results indicate that
the LsrB protein positively regulates succinoglycan production and biofilm formation
in A. tumefaciens.
The LsrB protein is essential for A. tumefaciens adaptation to oxidative stress
and iron limitation.
The increased expression of KatA exhibited by the S. meliloti lsrB deletion mutant
(Tang et al., 2013) suggests that this mutant is sensitive to oxidative stress. Similarly,
in the present study, we hypothesized that the A. tumefaciens lsrB deletion mutant
may also be sensitive to these oxidizing agents. To test this possibility, cell sensitivity
assays using hydrogen peroxide (H2O2) and sodium nitroprusside (SNP) were
performed. A. tumefaciens ∆lsrB cells were found to be hypersensitive to 10 mM
H2O2 and 10 mM SNP (Fig. 5), and this defect was rescued by expressing of the lsrB
gene from A. tumefaciens, B. abortus or S. meliloti (Fig. 5). These results suggest that
the ability of A. tumefaciens to resist oxidative stress is positively influenced by the
LsrB protein.
Bacterial adaptation to oxidative stress is associated with intracellular redox
homeostasis, which is influenced by levels of iron ions. To determine whether A.
tumefaciens lsrB contributes to iron transport, sensitivity to Dipy (2, 2-dipyridyl, a
metal ion chelator) was analysed. Our data indicated that the lsrB deletion mutant was
hypersensitive to Dipy both on solid and liquid media, and this defect was rescued by
expressing the lsrB gene from A. tumefaciens, S. meliloti or B. abortus (Fig. 6).
Moreover, addition of FeCl3 was able to restore the resistance of the mutant to Dipy
(Fig. 6). These data indicate that LsrB is a positive regulator of iron homeostasis in A.
tumefaciens.
The lsrB deletion mutant exhibits decreased survival in infiltrated tobacco
leaves.

To confirm that LsrB is required for A. tumefaciens transformation of host plants,
young tobacco leaves were used for infiltration experiments with suspensions of
bacteria harbouring the GUS reporter gene. Staining results indicated a lower level of
GUS expression in leaves infiltrated with the lsrB deletion strain than in leaves
infiltrated with the parent strain C58 C1 at the same bacterial density (Fig. 7A). It is
well known that plant wounds release several chemicals, including ROS (superoxide
anions and hydrogen peroxide) (Baker and Orlandi, 1995). To determine factors
affecting transformation efficiency, nitrobluetetrazolium (NBT) staining was used to
assess superoxide anion radical accumulation. The data confirmed that infiltrated
tobacco leaves produced large amounts of O2- (Fig. 7B-C). In addition, the bacteria
infiltrated into tobacco leaves were recovered, plated and counted. Starting one day
after inoculation, we detected a lower recovered bacterial cell density of the lsrB
deletion mutant than with the parent strain (Fig. 7D and Fig. S3), suggesting that the
proliferation or survival of A. tumefaciens cells in the wounds of host plants requires
the LsrB protein and may be associated with ROS sensitivity.
Downstream gene expression in the A. tumefaciens lsrB deletion mutant.
Due to the multiple phenotypic defects induced by lsrB deletion in A. tumefaciens, it
seemed plausible that multiple genes are differentially expressed in the mutant
compared with the parent strain. To assess this possibility, the whole-genome
transcriptomes of both the deletion mutant and the parent strain were analysed by
RNA-sequencing (RNA-Seq) (Table S3), and genes identified as being differentially
expressed were selected for confirmation by quantitative reverse transcription
polymerase chain reaction (RT-qPCR). The transcript levels of 14 of the selected
genes (attD, exoV, exoC, exoP, oxyR, trxA, Atu3676, Atu3679, Atu3680, Atu3688
(fecB), Atu3690 (fecD) and Atu3691 (fecE)) were decreased in the lsrB deletion
mutant, and oxidative stress (katA) and succinoglycan production (exoR) were
increased in the lsrB deletion mutant (Fig. 8). These data indicate that the expression
of several genes associated with adaptation to oxidative stress (oxyR, trxA),
succinoglycan production (exoV, exoC, exoP), siderophore biosynthesis (fecB, fecD,
fecE) and iron transporter (Atu3676, Atu3679, Atu3680) is positively regulated by the

Discussion
A. tumefaciens causes crown gall on plants and is used in plant genetic engineering.
Transformation of plant cells via A. tumefaciens depends on bacterial adaptation to
the environment of plant wounds. Indeed, bacteria have developed several strategies
to perceive environmental signals from plant wounds to reprogramme their gene
expression. Members of the LysR-type family of regulators are able to sense
environmental cues and function as key players in these processes (Schell, 1993;
Maddocks and Oyston, 2008). The lsrB gene, which was first identified in B. suis
(Foulongne et al., 2000) and later in S. meliloti (Luo et al., 2005), is essential for
alfalfa nodulation and nitrogen fixation by S. meliloti (Tang et al., 2013) and for
Brucella infection and survival in a human cell line and mice (Tang et al., 2013;
Sheehan et al., 2015). In this study, we found that LsrB, an A. tumefaciens LysR
family regulator, overcomes both oxidative stress and iron deprivation and controls
transformation efficiency in host plants. These findings are important for
understanding the regulatory mechanism of the interaction of A. tumefaciens with its
hosts.
For many years, att genes were proposed to mediate attachment and were also
reported to be required for virulence (Matthysse et al., 2000). However, the genome
sequence of A. tumefaciens C58 (Goodner et al., 2001; Wood et al., 2001) revealed the
att cluster to be located on the plasmid pAtC58, which is known to be dispensable for
virulence (Hynes et al., 1985). Analysis using isogenic derivatives revealed that
pAtC58 has only mild effects on virulence gene expression, with no obvious impact
on attachment (Nair et al., 2003). Although our data do not address whether the att
genes are directly associated with attachment, we note that it did find significantly
lower expression of attD as well as diminished attachment with the lsrB mutant (Figs.
3 and 8). Additionally, the avhB genes, these encode the T4SS that mediates
conjugation of pAtC58 was also decreased in the lsrB mutant (Table S3), this could
possibly be relevant to the diminished attachment.
Based on the results of our study, LsrB is a positive regulator of exopolysacchride

(including succinoglycan) production (Fig. 4), and we confirmed that LsrB positively
regulates succinoglycan biosynthesis by activating exo gene expression (Fig. 8). For
example, expression of exoR was upregulated in the lsrB deletion mutant. ExoR acts
as a negative regulator of succinoglycan biosynthesis by suppressing the ChvG/ChvI
two-component system, which directly activates expression of exo genes in both S.
meliloti and A. tumefaciens (Wells et al., 2007; Chen et al., 2008; Wu et al., 2012).
Therefore, our data suggest that increased levels of ExoR led to the repression of the
exo genes via ChvG/ChvI.
The plant transformation deficiency of the lsrB deletion mutant might largely result
from the decrease in bacterial adaptation to the environment. In this study, we found
the free-living lsrB mutant to be sensitive to oxidants (Fig. 5), which is consistent
with the observations in plants (Fig.7). Upon wounding, an oxidative burst is induced
in plants (Fig. 7B-C), and the sensitivity of the mutant to this condition may lead to
bacterial cell death (Fig. 7D). We also observed the mutant to be hypersensitive to
iron limitation (Fig. 6). Iron transport plays a crucial role in redox homeostasis (Imlay
et al., 1988), and iron limitation has been suggested to occur during bacterium-plant
interactions (Neema et al., 1993; Mila et al., 1996); thus, iron-limitation sensitivity
may also contribute to bacteria survival in wounds. Consistently, the expression of
genes related to the oxidative response and detoxification and iron transporters was
correspondingly altered in the mutant (Fig. 8).
The regulatory mechanism of LsrB in bacteria may be conserved. First, the lsrB gene
from B. abortus, A. tumefaciens or S. meliloti can complement the lsrB deletion
mutant phenotype in A. tumefaciens and S. meliloti (Figs. 1-6). Second, the LsrB
protein could directly regulate expression of lrp3 (though function of this gene is not
clear) in both S. meliloti and A. tumefaciens, as conserved TN11A boxes are predicted
to be present in the lrp3 promoter (Fig. S4) and the LsrB proteins directly binds to the
lrp3 promoter region in S. meliloti (Tang et al., 2014). In summary, our results reveal
that LsrB is a global regulator in the interaction of A. tumefaciens with host plants, a
finding that is important for understanding the molecular mechanism and evolution of
bacterial adaptation to biotic environments.

Materials and Methods
Bacterial strains, plasmids, and growth conditions.
All bacterial strains and plasmids used in this study are listed in Table S1. The
reagents and medium components were obtained from Dingguo Corporation (Beijing,
China) and Sigma-Aldrich (Mainland, China). All restriction enzymes and molecular
biology reagents were purchased from TakaRa (Dalian, China). DNA sequences were
determined by Shanghai RuiDi Biological Technology Corporation. The
oligonucleotide primers used in this study are listed in Table S2. Escherichia coli was
grown aerobically at 37°C in Luria-Bertani (LB) medium (Sambrook et al., 1989). A.
tumefaciens were grown aerobically at 28°C in yeast tryptone (TY) medium (Beringer,
1974) or Luria-Bertani (LB) medium. Antibiotics were used at the following
concentrations: chloramphenicol, 10 µg mL-1
; kanamycin, 50 µg mL-1
; gentamicin, 10
µg mL-1
; streptomycin, 500 µg mL-1
; rifampicin, 50 µg mL-1
and timentin, 200 µg
mL-1
.
Construction of deletion strains.
The constructed plasmids and primers used in this study are listed in Tables S1 and S2,
respectively. Fragments upstream and downstream of lsrBat were amplified using
primers P1 and P2 (upstream) and P3 and P4 (downstream). Primer P2 was designed
such that the 5’ sequence had reverse complementarity to primer P3. The
complementary sequence of these two primers facilitated splicing by overlapping the
extension of the two PCR products. Both flanking sequences were amplified and gel
purified. The two purified products were then used as both templates and primers (P1
and P4) in a second PCR reaction to generate the final spliced product, which was
ligated to pmD18 (TakaRa) and sequenced. The deletion construct was then excised
using restriction enzymes and ligated to the suicide vector pk18mobsacB (Schafer et
al., 1994) to produce plasmid pA1. The pk18mobsacB plasmid confers kanamycin
resistance and sucrose sensitivity. Plasmid pA1 was introduced into A. tumefaciens
C58C1 (Jelenic et al., 2000) via mating using MT616 (Finan et al., 1984), and A.
tumefaciens C58C1 was obtained from Shanghai Weidi Biotechnology Co., Ltd.

Exconjugants with kanamycin resistance were screened on LB plates and selectively
grown on fresh LB plates containing 13% sucrose. The resulting colonies were tested
for neomycin sensitivity. Corrected lsrBat mutants were confirmed by PCR using
primers (P5/P6) flanking the deletion site.
Plasmid expression constructs.
To construct a plasmid for complementation of the ∆lsrBat mutant, an lsrB DNA
fragment that included the native promoter was PCR amplified from the genomic
DNA of A. tumefaciens C58C1 using primers P9/P10. The PCR product was cloned
into pSRK (Khan et al., 2008), and the plasmid was named plsrBat. The B. abortus
2308 lsrB homologue, including its native promoter, was amplified using primers
P7/P8 and cloned into pSRK; the plasmid was named plsrBba. The S. meliloti 1021
lsrB homologue, including its native promoter, was amplified using primers P11/P12
and cloned into pSRK; the plasmid was named plsrBsm. The constructs were
introduced into the ∆lsrBat strain via conjugation.
RNA extraction.
Subcultures were started by inoculation of 50 mL of fresh TY medium with 5% of
overnight cultures and allowed to grow to log phase (OD600 = 0.5), RNA was isolated
using TRIZOL Reagent (Invitrogen, 15596026) and cDNA was prepared using a kit
(TakaRa, 0047A). An Agilent 2100 Bioanalyzer was used to assess the integrity of the
RNA samples. RNA-Seq was carried out by Shanghai Bohao Biological Technology
Corporation. The accession number for the RNA-seq date is GEO: GSE108845.
qPCR primers were designed to amplify approximately 200-bp sequences from the
indicated genes. The primer sequences are provided in Table S2. The qPCR procedure
was performed with SYBR Green reagent (YEASEN, Shanghai, China). Sample
values were normalized using a ropD primer set and calibrated against the results for
wild-type.
Nodulation tests.
Nodulation assays using alfalfa plants were performed as reported previously (Tang et
al., 2013). Briefly, alfalfa seeds were surface sterilized and germinated. Alfalfa
seedlings were soaked for 30 min in a diluted bacterial solution (OD600 = 0.05), and

transferred to pots filled with a mixture of autoclaved vermiculite and perlite (3:1).
After inoculation, the number of nodulated plants and the dry weight of shoots were
recorded for four weeks. The plants were watered with autoclaved nitrogen-free liquid
medium every 3 days.
Transient GUS activity assays of Arabidopsis plants.
Transient Agrobacterium-mediated transformation assays were performed as
described by Nam et al. (Nam et al., 1999) and Mysore et al. (Mysore et al., 2000).
For transient GUS activity assays (Mestiri et al., 2014), root segments from
10-day-old seedlings grown in vitro were pooled and co-cultivated with A.
tumefaciens harbouring the binary vector pCAMBIA2301 (Cambia, Canberra,
Australia) in hormone-free Murashige and Skoog (MS) medium for 48 h at 22°C.
Next, the seedlings were washed once in hormone-free MS medium and then cultured
in hormone-free MS medium supplemented with timentin for an additional 4 days to
kill the bacteria. Roots were subsequently stained with GUS buffer (100 mM
Na2HPO4, 100 mM KH2PO4, 10 mM EDTA, 0.5 mM K3Fe(CN)6, 0.5 mM K4Fe(CN)6,
1 mg mL-1
x-gluc, pH 7.0) overnight at 37°C. The stained samples were rinsed three
times with 1× phosphate-buffered saline (PBS) and cleared in different concentrations
of ethanol. The number of blue spots per root segment was counted, and three
independent experiments were performed.
Plant attachment assays.
Arabidopsis root attachment assays were carried out as previously described
(Tomlinson et al., 2010), with minor modifications. Roots of 5-day-old A. thaliana
seedlings grown on MS agar medium were transferred to sterile dishes containing 15
mL 1 mM CaCl2 and 0.4% sucrose. Next, the seedlings were inoculated with OD600 =
0.01 of the appropriate derivative strain of A. tumefaciens carrying the GFP reporter
plasmid pHC60 (Cheng and Walker, 1998). Ten root segments were inoculated per
strain. After 2 h of incubation in the dark at room temperature, the root segments were
rinsed and resuspended in fresh calcium chloride/sucrose solution. Five roots were
used to count the number of bacteria (colony-forming units (CFU) mL-1
), and another
five roots were sealed under coverslips. Fluorescence microscopy was performed

Transient GUS activity assays of tobacco plants.
A. tumefaciens cells harbouring the binary vector pCAMBIA2301 were harvested by
centrifugation. The cells were suspended in sterile water to an optical density OD600 of
0.2, corresponding to approximately 2 × 107
colony-forming units (CFU) per mL.
Half of a leaf (four weeks) was infiltrated with the A. tumefaciens C58C1 bacterial
suspension through the stomata on the abaxial side using a 1 mL plastic syringe
(without a needle). The second half of the leaf was inoculated with the ∆lsrBat
mutant. After 2 days, the leaves were stained with with x-gluc and
Nitrobluetetrazolium (NBT ) buffer.
Surviving bacterial counts.
To determine bacterial growth in tobacco leaves, wild-type tobacco plants (six weeks
old) were syringe inoculated with the C58C1 or ∆lsrBat strain (5 × 106 CFU/mL). The
internal bacterial number was determined at several time points (after 0, 1, 2, 3, 4 dpi)
via surface sterilization of a 1-cm2 section of inoculated plants with 5% H2O2 for 3
min (Ishiga and Ichinose, 2016). After washing three times with 100 µL sterile
distilled water, the plants were homogenized in sterile distilled water and the diluted
samples were plated on LB medium. Two to three days after plating of the diluted
samples, the bacterial CFU were counted. Bacterial numbers were evaluated in three
independent experiments.
Assay of superoxide anion radicals.
NBT (Sigma) was used to detect superoxide. Samples were stained with 3.5 mg/mL
NBT in 0.1 M potassium phosphate at pH 7.0 and vacuum-infiltrated three times (10
min each) in NBT staining solution. After infiltration, leaves were stained for 2 h at
room temperature followed by a wash with distilled water. The samples were then
cleared in 75% ethanol.
Assay for succinoglycan or EPS levels.
A. tumefaciens colonies were inoculated into LB liquid medium and grown overnight
at 28°C with shaking. The cultures were normalized to an OD600 of 0.2, and 5 µL was
spotted onto LB plates supplemented with 0.02% Calcofluor White M2R (Sigma).

The plates were incubated for 2 days at 28°C, and succinoglycan production was
visualized under visible and UV light (Yao et al., 2004; Wang et al., 2013). All strains
were imaged using the same exposure value. The fluorescence intensity was analysed
using ImageJ Software. Next, 0.25 mL of A. tumefaciens strains, cultured to stationary
phase in LB, and 0.75 mL of isopropanol was added to precipitate EPS. The pellet
was washed once with 70% ethanol, air dried, redissolved in 0.25 mL of distilled
water, and used for total EPS measurements using the sulphate-anthrone method
(Wang et al., 2010).
Biofilm formation.
Biofilm formation in glass tubes was investigated using the method described by
Calatrava-Morales et al. (Calatrava-Morales et al., 2017), with modification. Briefly,
outgrown cultures of the tested strains were diluted 100-fold in glass tubes containing
4 mL fresh LB broth. The tubes were incubated for 48 h at 28°C under shaking
conditions for quantification of biofilm levels. After incubation, liquid from the tubes
was removed, and the bacterial biofilms were stained with 4 mL 0.1% crystal violet
solution (Sigma-Aldrich) for 20 min. The tubes were carefully washed three times
with deionized water to eliminate excess crystal violet. The crystal violet was
solubilized by the addition of 2 mL acetic acid (30% v/v), and absorbance at 590 nm
was used for quantification of the solubilized crystal violet stain.
Assay of oxidative stress sensitivity.
The sensitivity of A. tumefaciens to SNP was examined by growing cells in LB
medium at 28°C with shaking at 200 rpm/min to OD600 = 0.5, followed by
centrifugation. The cultures were serially diluted tenfold in LB broth, and aliquots (5
µL) were spotted onto LB agar supplemented with 10 mM H2O2 or 10 mM SNP to
determine the oxidative resistance of the strains at 28°C for 4 d.
Sensitivity to Dipy.
Overnight cultures grown in TY medium were washed once with fresh TY medium;
the cells were diluted to an OD600 of 0.05, and an iron-limiting condition was
achieved by adding 0.1 mM concentration of the iron chelator 2,2-dipyridyl (Dipy;
Sigma). Growth was monitored by measuring the OD600 after incubation at 28°C with

shaking for 36 h. The effect of addition of metal ions on bacterial growth in the
presence of Dipy was assayed on TY agar plates. Overnight cultures grown in TY
medium were washed and adjusted to an OD600 of 0.03 in TY medium. Tenfold serial
dilutions were made. An aliquot (5 µL) of each dilution was spotted onto TY agar
plates containing 0.2 mM Dipy and 0.1 mM of FeCl3 and then incubated at 28°C for 4
d. Cells spotted onto an TY agar plate were used as a control.
Growth curves.
Bacteria were cultured in LB broth, and cells in the exponential growth phase were
diluted in fresh medium to OD600 = 0.05. The cell density (optical density at 600 nm
[OD600]) was monitored at each time point.
DNA sequence analysis.
The deduced protein sequence of LsrB was downloaded from the Sinorhizobium
meliloti genome site (http: //iant.Toulouse.inra.fr/bacteria/annotation/cgi/rhime.cgi).
Homologues of LsrB were aligned and downloaded from NCBI Blast Microbial
Genomes (http: //www.ncb i.nlm.nih.gov/sutils/genome_table.cgi).

Fig. S2 Growth of A. tumefaciens lsrB mutants. Bacteria were cultured in LB/MC
medium. Cells in the exponential growth phase were diluted in fresh medium to
OD600=0.03. Cell density (optical density at 600 nm [OD600]) was monitored over time.
The figure shows the results of a typical experiment, which was performed three times.
