Organic breeding should select for plant genotypes able to efficiently exploit indigenous Probiotic Rhizobacteria

In order to rapidly achieve crop varieties adapted to organic crop production systems, it is of crucial importance to know plant genotype potential for positive interactions with soil indigenous micro-flora. In this frame, European research efforts are now considering beneficial (plant-probiotic) rhizobacteria as an essential factor for sustainable plant breeding. Published findings are beginning to elucidate how probiotic rhizobacteria contribute to plant nutrient assimilation and disease resistance. Future efforts for crop breeding in organic agriculture should take into the right account the evolutionary need of plants to exploit indigenous probiotic rhizobacteria, expecially in low-input cultural conditions.
