摘要：

Rheum palmatum, a well-known Traditional Chinese Medicines (TCM), has been used for medical purposes for thousand years in China. However, endophyte diversity of R. palmatum among different tissues and ages is still not revealed. In this study, we used 16S and ITS amplicon sequencing and combined with PICRUSt and FUNGuild to compare endophyte diversity and ecological function among different tissues and ages of R. palmatum. The results showed that the diversity and OTUs (Operational taxonomic units) abundance of endophytic fungi and bacteria of R. palmatum differed among different tissues and ages. The predictive function analysis showed that metabolism was main function of endophytic bacteria in different tissue and year samples, while saprotroph was dominant trophic mode of endophytic fungi in different year samples. The dominant trophic modes of endophytic fungi were saprotroph, pathotroph-symbiotroph and symbiotroph, and relative abundances differed in the different tissue samples. Our results elucidated the comprehensive diversity and composition profiles of endophytes in different tissues and year of R. palmatum. Our data offered pivotal information to clarify the role of endophytes in the production of R. palmatum and its important metabolites.
