A flavonoid-attracted Aeromonas spp enhances plant drought resistance without cry-for help

Flavonoids are stress-inducible metabolites important for plant-microbe interactions. It is unclear whether and how flavonoids may contribute to plant stress resistance through affecting non-nodulating bacteria in the root microbiome. Here we show how flavonoids preferentially attracts Aeromonadaceae in Arabidopsis thaliana root microbiome and how flavonoid-dependent recruitment of an Aeromona spp. results in enhanced plant drought resistance.
