Bacterial Diversity of Grapevine Rhizosphere Soil Revealed by High-Throughput Sequence Analysis from Different Vineyards in China

The bacterial communities and biodiversity in rhizosphere soil of healthy grape at maturity stage were investigated by method of metagenomic sequencing. The results showed that the longer the years of plant, the higher the corresponding richness and diversity of bacterial communities in grape rhizosphere soil, and the biodiversity of grapevine rhizosphere soil was also depended on varieties themselves. Besides, species of Bradyrhizobium, Phenylobacterium, Devosia, Cellvibrio, Mycoplana and Prosthecobacter were relatively abundant in the grape rhizosphere soil at Kefeng vineyard, while Nocardioides, Cellulomonas, Flavobacterium, Promicromonospora, Streptomyces, Bacillus, Bacteroides, Lactobacillus and Lactococcus were as the main bacterial species at Zixuan vineyard. Based on metagenomic analysis, the compositions of bacterial community in grape rhizosphere soil are related to the different soil environment, and Gemmatimonadetes and Acidobacteria may act as one of the factors for the healthy growth of wine grapes. These results will improve our understanding of soil microbial community for the further research basis for the development and utilization of microbial resources.
