Unravelling the molecular evolution of plant-microbiome interactions in drylands
How plants evolved to shape their microbiota is a long-standing question in ecology and evolution. I posit that the microbiome forms a crucial part of how plants adapt to changing environments and that this microbiota optimization should be manifested in a strong genomic and phenotypic signature of adaptation. I propose to use natural plant variation and biogeography to dissect how plants evolved along with their microbiota to cope with aridity. Eight within-genus pairs of Brassicaceae species have been identified, distributed vicariously across a steep precipitation gradient. These species pairs represent eight independent instances of adaptation to aridity. This natural distribution…
