Losses in agricultural products(cereals)

While in Europe and the US the majority of food is wasted bythe consumer,in Asia and Africa more than 60% of losses are on the farm leveland post harvest handling.

Improvement of agriculture can make a huge difference!

We cannot go back to “good old traditional agriculture”!

It does not feed farmer families (subsistance farming)It does not feed the growing population in the citiesIt is hard and inefficient labor for farmersIt has large pre- and post harvest lossesIt does not provide better qualityIt requires additional land use

Subsistance farming kills progress, development, economy, wealth.

Political „incorrectness“ – a personal statement

Europe can promote low production agriculture (called “eco-farming”).We just import what we cannot produce – on the costs of developing and emerging countries.

Germany is the largest consumer in „Bio-products“, ecological agriculture is heavily subsidised, pricesfor „Bio-products“ are 30% to 60% higher than conventional, consumer needs are constantly increasing.Production is not increasing. On average, 70% of „Bio-products“ are imported.

Political „incorrectness“ – a personal statement

Germany just decided to be “GMO-free”, i.e. gene technology is prohibited in agriculture.But Germany imports large amounts of agricultural GMO products,most GMO enzymes for food processing and non-food products.

European politics and NGOs export “GMO-free ideology”:NGOs prevented Golden Rice cultivation in Asia for more than 15 years – continued with Brinjal.GMO cotton production by small hold farmers is heavily opposed by western pressure groups.GMO soy bean production in South America is opposed by Germany politicians.

Mutagenesis1930 random mutagenesis was introduce in plant breeding.Seedlings are exposed to chemical mutagens or radiation to approx. 90% lethality.Surviving plants are back-crossed and tested for desired traits.

Several 1000 mutagenised crop plants and their offspring are on the market.Mutated genes are not characterised. Approx. 20 unidentified mutations persistin commercialised crop plants.

Random mutagenesis has considerably improved crop plants.It is still being done but the outcome of the shot-gun approach is unpredictable.It is time consuming/impossible to cross out all unidentified mutations.Several desired traits have been accidentally lost by mutation breeding.

Today, random mutagenesis is mostly replaced by precision methods ofgene technology – but these are not accepted in Europe.

MAS (marker assisted selection)To combine desired traits from two plants (e.g. high yield and draught resistance) crossing i.e. mixing thecomplete genomes is required.Many traits are multigenic, i.e. “high yield” depends on a combination of several specific genes (alleles).Selection for the “good” and against the “bad” traits has to be done over many generations.

MAS is based on extensive genome mapping and association ofgenes with molecular markers.

Molecular analysis of the offspring immediately reveals whichrecombined plants have the desired genes and are good forfurther breeding.

“Conventional” agrobacterium gene technology – transgenetics

Agrobacterium tumefaciens is a natural gene transfer shuttle that inserts tumor genesinto plants.

From the bacterial DNA the natural tumor geneswere removed and any other gene of interest canbe inserted.Agrobacterium infection works in most plants.

The most common traits in transgenic crop plants are resistances againstvarious insect pests by cry genes from bacillus thuringiensis or by the EPSPSgene from agrobacterium tumefaciens which confers resistance to theherbicide Glyphosate.

“Conventional” agrobacterium gene technology – cisgeneticsThe term cis-genetics is used when genes from the same species are being used ingene technology.

Examplesintroduction of Phytophthora resistance from wild potato into commercial cultivars.Introduction of resistance against the fungal disease apple scab from wild apples.Note: these are genes that have been lost during conventional breeding!

Gene “Knock-downs” may also be considered as cisgenetics: an endogeneconstruct is used to “knock-down” or “silence” a gene.

ExamplesArctic apple where the enzyme PPO has been knocked down,Sunflower with knocked down desaturase producing more unsaturated fatty acids.

“Advanced” gene technology, multiple genes to construct biochemical pathways

Biochemical pathways towards a desired endproduct frequently require several enzymatic steps.

Researchers in Zurich and Geneva have generated a cassava plant with twogenes from Arabidopsis that produces several times as much Vitamin B6as conventional plants. Especially in subsaharan Africa, Vitamin B6deficiency is prevalent.

The best known example is Golden Rice where genes from a soil bacteriaand from daffodil were introduced into the rice genome. The transgenicrice produces sufficient beta-carotine to prevent Vitamin A deficiency.

The UK based company Ecover, togetherwith the Californian biotech companySolazyme, have genetically engineeredalgae to produce palm oil-like fatty acids.To reconstruct complete biochemicalpathways in an organism in order toproduce e.g. other fatty acids, is called“synthetic biology”.

Production and further development was stopped in 2014 after powerfulcampaigns by 23 NGOs against the “extreme biotechnology” employed bySolazyme.

A serious (?) suggestion by “Friends of the Earth” was to usecoconut oil instead of palm oil.

Since genomes and many gene functions are known for many crop plants,knowledge-based changes can be introduced to improve crop traits.

Entirely new products can be made in plants to improve nutritional value.

Mis-use will never be completely excluded.But we cannot ignore a technology that provides so many chances!

GMOs promote resistance in pest insects and resistance to herbicides.

Resistances always evolve. Against herbicides, pesticides, antibiotics, immunisation,drugs against HIV, Dengue, Malaria.

Resistance management is easier with GM crops:targeted spraying management for herbicides, refuge zones for insect pests.

GM crops reduce crop rotation for economical reasons.

Crop rotation conserves soil qualityand reduces pests.Crop rotation conserves soil qualityand reduces pests.

GM crops have advantages and disadvantages.They should be considered as just another way of plant breeding.

There should be no competition between „ecological farming“ and „GMO farming“ –they should rather complement each other:• Spraying less pesticides is ecological• Draught resistant crops are ecological• Increasing nutritional value is ecological• Using less space for more yield is ecological• Plants growing on poor soil are ecological

There should be no competition between „ecological farming“ and „GMO farming“ –they should rather complement each other:• Spraying less pesticides is ecological• Draught resistant crops are ecological• Increasing nutritional value is ecological• Using less space for more yield is ecological• Plants growing on poor soil are ecological

Careful evaluation for safety and ecological effects is absolutely necessary.For GM crops as well as for conventional breeding.

A clever combination of GMOs and conventional/traditional cultivars will help solving(part of) the problems to feed the world.

Germany was leading in the development of plant genetic engineering.The inventor of CRISPR/Cas9 is a Max-Planck director in Germany.

But applications of these technologies are now prohibited in Germany.

Industry using these technologies is moving out of Germany.

Many researchers in applied plant genetic engineering are moving out of Germany.

But Germany is still a high technology country.It still has a good infrastucture for molecular plant researchIt is still innovative and highly advanced in plant molecular biology.It is still a good place for training in modern plant sciences!
