Plant genotype: a lever in the interactions between plant and its associated rhizosphere microbiome
2018
International audience; In the context of highly pressured agricultural production using low levels of inputs, cropping strategies could take advantage of existing plant-microbiome interactions that can improve both plant growth and health. We believe that plant genetics can provide some clues to better understand the mechanisms underlying microbiome recruitment by the plant.The aims of this work were (i) to assess plant genotype effect on the rhizosphere bacterial communities in relation to the plant nutritional strategies for a core collection of 155 genotypes of Medicago truncatula and (ii) to highlight the genetic determinisms potentially associated in these interactions. To achieve the…
A new conceptual framework shows that plant genotype and soil nitrogen availability modify both plant nutritional strategies and diversity of their a…

In the context of sustainable agriculture, it is desirable to lower the input of mineral fertilizers. Therefore, we need to select ‘new’ genotypes that are both adapted to ‘low fertilizer inputs’ and more efficient in nutrient use. A better understanding of plant-microbe interactions under low input of fertilizers is now needed. Nevertheless, in microbial ecology, conceptual frameworks or models are used to analyse plant-microbe interactions but plant phenotype is currently viewed as a “black box”. We developed a new conceptual framework to study plant-microbe interactions using a multidisciplinary approach combining Microbial Ecology and Plant Ecophysiology.The links among plant genotype, …
