A flavonoid-attracted Aeromonas spp enhances plant Na_H1 resistance without cry-for-help [Bacteria_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 Na_H1 resistance. Examination of 2 different samples of Aeromonas spp H1 with and without Naringenin treatment, each of samples contains 3 biological replicates. They are named as mock and Na-H1.
