A flavonoid-attracted Aeromonas spp enhances plant drought resistance without cry-for-help [Plant_RNA-seq]

Flavonoids are stress-inducible metabolites important for plant-microbe interactions. In contrast to their well-known function in initiating rhizobia nodulation in legumes, 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. Examination of 4 different samples of Col-0, each of samples contains 3 biological replicates. They are named as mock, drought, H1 and H1+drought, respectively..
