Patterns in the Microbial Community of Salt-Tolerant Plants and the Functional Genes Associated with Salt Stress Alleviation.

ABSTRACT: Salinity is an important abiotic stress affecting plant growth. We have known that plants can recruit beneficial microbes from the surrounding soil. However, the ecological functions of the core microbiome in salt-tolerant plants, together with their driving factors, remain largely unexplored. Here, we employed both amplicon and shotgun metagenomic sequencing to investigate the microbiome and function signatures of bulk soil and rhizocompartment samples from three salt-tolerant plants (legumes Glycine soja and Sesbania cannabina and nonlegume Sorghum bicolor). Strong filtration effects for microbes and functional genes were found in the rhizocompartments following a spatial gradient. The dominant bacteria belonged to Ensifer for legumes and Bacillus for S. bicolor. Alt
