Abstract

Metagenomic analysis was applied to bacterial communities associated with the shoots of two field-grown rice cultivars, Nipponbare and Kasalath. In both cultivars, shoot microbiomes were dominated by Alphaproteobacteria (51-52%), Actinobacteria (11-15%), Gammaproteobacteria (9-10%), and Betaproteobacteria (4-10%). Compared with other rice microbiomes (root, rhizosphere, and phyllosphere) in public databases, the shoot microbiomes harbored abundant genes for C1 compound metabolism and 1-aminocyclopropane-1-carboxylate catabolism, but fewer genes for indole-3-acetic acid production and nitrogen fixation. Salicylate hydroxylase was detected in all microbiomes, except the rhizosphere. These genomic features facilitate understanding of plant-microbe interactions and biogeochemical metabolism in rice shoots.
