| Description: |
Endophytic microbial communities play an important role in plant development, nutrient acquisition, and oxidative stress tolerance. Oryza officinalis and Oryza meyeriana are unique wild rice varieties in China with many high-quality resistance genes, rich endophyte diversity, and potential resources for sustainable agriculture. In the present study, the endophytic microbial community structures of O. officinalis , O. meyeriana , and cultivated rice were compared using metagenomic sequencing. Dechloromonas , Salmonella , Klebsiella , and Listeria were the core microbial groups in wild and cultivated rice. The relative abundances of Ligilactobacillus , Escherichia , and Bradyrhizobium in O. meyeriana were higher than those in cultivated rice. The relative abundances of Listeria , Acinetobacter , Escherichia , and Dechloromonas in O. officinalis were also higher. Compared to that of cultivated rice, the microbiota of wild rice had a more complex and stable community network. At the pathway level 2 based on the Kyoto Encyclopedia of Genes and Genomes classification system, the relative abundance of metabolic categories was dominant. Most pathways showed that the O. officinalis relative abundance was higher than those of the other two species. Our study revealed differences in the leaf endophyte community structure and function between wild and cultivated rice in the same habitat, demonstrating the potential of wild rice in recruiting specific microorganisms to improve crop performance and promote safe and sustainable food production. IMPORTANCE Under the current climate change environment, plant-beneficial endophytes are of great significance for promoting food production. Modern cultivars may have lost many beneficial endophytes compared to their ancestors. However, relatively few studies have been conducted on the community structure and function of modern ancestral crop endophytes. In this study, the composition and function of the microbial communities of two wild rice species were analyzed; the ... |
