Microbial community analysis of apple rhizosphere around Bohai Gulf.

ABSTRACT: Bohai Gulf is the main area for apple tree cultivation in China. Consecutive replanting significantly affects the yield and quality of apple trees in this area. Microecological imbalance in apple trees' rhizospheres caused by variation in the soil microbial community is considered the primary cause of apple replant disease (ARD). This study analysed the microbial communities of the rhizospheres of perennial apple trees (PAT) and apple tree saplings under replanting (ATS) around Bohai Gulf using high-throughput sequencing. The results revealed increased populations of typical pathogenic fungi Verticillium and bacteria Xanthomonadaceae, and decreased populations of beneficial bacterial populations Pseudomonas and Bacillus with replanting, suggesting that competition between pathogens and ben
