Rhizobacterial diversity, community composition, and the influence of keystone taxa on O'Neal blueberry (Vaccinium corymbosum).

ABSTRACT: Rhizosphere microbiotas play vital roles in resisting environmental stress, transforming soil nutrients, and promoting plant health, growth, and productivity. The effects of rhizosphere microbial community shaping and the characteristics and functions of keystone taxa on blueberries were comprehensively studied by examining the rhizobacteria of healthy old trees (O), young seedlings (OG), and poorly growing seedlings (OB) of O'Neal blueberries. Our results showed that rhizobacterial diversity followed the order OB > > OG > O, and the microbial community of OG was similar to that of O, while that of OB was distinctly different. The predominant rhizobacteria identified included Actinobacteria, Proteobacteria, Firmicutes, Chloroflexi, and Acidobacteria. F
