The soft rot in pitaya (
spp.) stems seriously affected the harvest of pitaya fruits, but the dynamic change characteristics of bacterial community in pitaya stems during soft rot stages had not been revealed. In this study, we analyzed the bacterial community composition of different soft rot stages and visualized functional annotations of the core bacterial community in five soft rot periods via the Illumina high-throughput sequencing technology, MetaCoMET online network platform, and FAPROTAX database. The results showed that the dominant bacteria in healthy and diseased pitaya stems were Proteobacteria and Firmicutes.
were the core bacteria microbiomes during the infection stages. Meanwhile, the ecological function analysis results showed that the
bacteria may play an important role in causing soft rot of pitaya stems. Therefore, the results shown in this paper could provide a useful reference for the study on microecological mechanism of soft rot of pitaya stems.
