Abstract

Plant–microbe interactions affect ecosystem function, and plant species influence relevant microorganisms. However, the different genotypes of maize that shape the structure and function of the rhizosphere microbial community remain poorly investigated. During this study, the structures of the rhizosphere microbial community among three genotypes of maize were analyzed at the seedling and maturity stages using high-throughput sequencing and bioinformatics analysis. The results demonstrated that Tiannuozao 60 (N) showed higher bacterial and fungal diversity in both periods, while Junlong1217 (QZ) and Fujitai519 (ZL) had lower diversity. The bacterial community structure among the three varieties was significantly different; however, fewer differences were found in the fungal community. The bacterial community composition of N and QZ was similar yet different from ZL at the seedling stage. The bacterial networks of the three cultivars were more complex than the fungal networks, and the networks of the mature stages were more complex than those of the seedling stages, while the opposite was true for the fungi. FAPROTAX functional and FUNGuild functional predictions revealed that different varieties of maize were different in functional abundance at the genus level, and these differences were related to breeding characteristics. This study suggested that different maize genotypes regulated the rhizosphere bacterial and fungal communities, which would help guide practices.
