Drought stress impacts the microbiota mediating iron dynamic in the pea rhizosphere

Agroécologie, INRAE, Institut Agro, Université de Bourgogne - Université de Bourgogne Franche-Comté, Dijon, FranceMicrobiota, with their consortia of genomes, extend the genetic repertoires of host plants to form ‘extended genotypes’, resulting in extended host phenotypes. Trecently, the term ‘holobiont’, which encompasses the host plant plus its associated microbiota, has been proposedHow environmental properties impact both the plant and microbial components of the holobiont, and its phenotype, still remain to be explored.We addressed this question by testing the impact of different abiotic conditions (drought stress and soil pH) on plant and microbial phenotypes in relation to iron. Iron…

Holobiont interactions occurring in pea-wheat intercropping impact both plant phenotype and the associated microbiota
