Metagenomic evidence of stronger effect of stylo (legume) than bahiagrass (grass) on taxonomic and functional profiles of the soil microbial community.

ABSTRACT: Plants are key determinants of soil microbial community (SMC). Legumes and grasses are distinct groups in various ecosystems; however, how they differentially shape SMC structure and functioning has yet to be explored. Here, we investigate SMC in soils grown with stylo (legume) or bahiagrass (grass). Soil metagenomic sequencing indicates that Archaea was more abundant in unplanted soils than in planted soils, and that stylo selected higher abundance of fungi than bahiagrass. When the stylo soils enriched Streptomyces, Frankia, Mycobacterium and Amycolatopsis, the bahiagrass soils enriched Sphingomonas and Sphingobium. NMDS reveals that the legume shaped SMC more greatly than the grass (P < 0.004). SMC functional profiles (KEGG and CAZy) were also greatly altered by plants with the legume b
