, an epiphytic plant, is a traditional medicinal herb with abundant endophytes. It is unclear whether the variation in the diversity and abundance of endophytes could stimulate the biosynthesis of medicinal compounds in the plant. In this study, we collected fresh stems of from four habitats for investigating the fungal community structure, dendrobine content, and environment factors and their correlations. The results indicated no significant difference in endophytic fungal diversity among the habitats; however, different dominant or special endophytic genera were observed in the hosts from different habitats. The altitude was observed to be positively related to the dendrobine content, as the stems collected from the altitude of 692 m exhibited the highest level of dendrobine. Furthermore, the relative abundance of was found to be positively correlated with the altitude and dendrobine content. The epiphytic matrix exhibited a significant negative correlation with the relative abundance of the endophytic fungus but did not exhibit any significant correlation with the dendrobine content. The results indicated that the abundance of endophytes in was affected by the altitude and epiphytic matrix and that high abundance and high altitude were conducive to dendrobine production.
[植物名称]，一种附生植物，是一种具有丰富内生菌的传统药草。尚不清楚内生菌多样性和丰度的变化是否会刺激该植物中药用化合物的生物合成。在本研究中，我们从四个生境收集了[植物名称]的新鲜茎，以研究真菌群落结构、石蒜碱含量、环境因子及其相关性。结果表明，各生境间内生真菌多样性无显著差异；然而，在来自不同生境的宿主中观察到了不同的优势或特殊内生属。观察到海拔与石蒜碱含量呈正相关，因为从692米海拔处采集的茎石蒜碱含量最高。此外，[真菌属名称]的相对丰度与海拔和石蒜碱含量呈正相关。附生基质与内生真菌[真菌属名称]的相对丰度呈显著负相关，但与石蒜碱含量无显著相关性。结果表明，[植物名称]内生菌的丰度受海拔和附生基质的影响，高[真菌属名称]丰度和高海拔有利于石蒜碱的产生。
