Studies on the Composition and Diversity of Seagrass <i>Ruppia sinensis</i> Rhizosphere Mmicroorganisms in the Yellow River Delta

Abstract

Seagrass is a significant primary producer of coastal ecosystems; however, the continued degradation of seagrass beds is a serious problem that has attracted widespread attention from researchers. Rhizosphere microorganisms affect seagrass and participate in many life activities of seagrass. This study explored the relationship between the composition of microbes in the rhizosphere and the surrounding environment of Ruppia sinensis by using High-throughput sequencing methods. The dominant bacterial groups in the rhizosphere surface sediments of R. sinensis and the surrounding environment are Proteobacteria, Bacteroidota, and Firmicutes. Moreover, the dominant fungal groups are Ascomycota, Basidiomycota, and Chytridiomycota. Significant differences (p R. sinensis, which provided extensive evidence of the relative contribution of the seagrass rhizosphere and the surrounding environment.
