- Abstract
Using microbial diversity sequencing technology, bacterial communities in cultivation substrates of two kinds of diseased Flammulina filiformis, mycelial sluggish growth disease during mycelial growth and young fruiting body blight disease during fruiting body development, were analyzed. The results showed that bacterial diversity in cultivation substrates gradually decreased from mycelial growth to fruiting body development, and their dominant bacteria were different. Compared with normal substrate, substrates of diseased F. filiformis showed a significant decrease in bacterial diversity and different dominant bacteria. The correlation network of dominant bacteria at the genus level showed that the pathogenic bacteria inhibited other bacteria in the cultivation substrates of the diseased F. filiformis. In the substrate samples of mycelial sluggish growth disease, the genus Pseudomonas inhibited the growth of other bacteria in the community. In the substrate samples of young fruiting body blight disease, the genus Arthrobacter mainly inhibited the growth of Amycolatopsis; and the genus Pseudomonas indirectly inhibited Leucobacter, Prochlorococcus and Pseudoclavibacter. There was an indirect negative correlation between Arthrobacter and Pseudomonas. These findings provided understandings on substrate bacterial community structures of F. filiformis at different developmental stages, and the relationship between incidence of bacterial diseases and substrate bacterial community diversity, and thus can be used to establish an early warning mechanism for disease occurrence based on microbial diversity.
