摘要： Examining the endophytic bacteria in rice seeds from Yunnan Province displaying regional characteristics is vital for exploring strain resources, improving rice production, and conducting subsequent research. This study investigated nine characteristic rice varieties from Yunnan Province using high-throughput sequencing technology based on the Illumina Novaseq platform to reveal their dominant bacterial communities and discussed their endophytic bacterial community differences. A total of 829 shared OTUs, and 233 unique OTUs were identified in the nine samples, while the bacteria included Proteobacteria, Actinobacteriota, and Firmicutes, of which Proteobacteria was the most dominant. Pantoea and Methylorubrum were the most abundant at the genus level, with Curtobacterium, Brevundimonas, and Luteibacter representing the specific genera in the rice seed samples. This study revealed the endophytic structure and diversity in the seeds of nine rice varieties displaying regional characteristics and provided a foundation for further research into rice containing endophytic bacteria.
