Figure S1 – Abundance of 16S bacterial (A), Variovorax asfA (B) genes in the bulk soil per sampling in the B and V soils. Buinen [B], Valthermond [V], young plant [s], flowering [f], senescence [sn], bulk [b], before planting [p]], after harvesting in winter [w]

Figure S2 – Phylogenetic analysis of ß-proteobacterial 16S rRNA genes retrieved from cultivar P (A) and A (B) in B soil at flowering stage. The evolutionary history was inferred using the Neighbor-Joining method. The evolutionary distances were computed using the Kimura 2- parameter method and bootstrap values (1000 repetitions).
