subsp. Rousi (Abbrev. ) stands as a vital botanical asset in ameliorating the ecological landscape of the arid regions in Northwest China, where its rhizospheric microorganisms serve as linchpins in its growth and developmental dynamics. This study aimed to explore the community structure characteristics and origin differences of root endophytic fungi in . Samples were collected from 25 areas where is naturally distributed along an altitude gradient in the northwest region. Then, endophytic fungi from different regions were analyzed by using high-throughput sequencing technology to compare the structural characteristics of endophytic fungi and examine their association with environmental factors. FUNGuild was employed to analyze the community structure and functions of endophytic fungi, and the results showed that each region had its own dominant endophytic fungal flora, demonstrating the differences in origin of endophytic fungi, and the specific endophytic flora acquired from the original soil in the growing season of will help us construct the microecological community structure. Furthermore, the study identified and assessed the diversity of fungi, elucidating the species structure and highlighting dominant species. The RDA analysis revealed that available phosphorus (AP), available potassium (AK), and total nitrogen (TN) exhibit significant correlations with the composition and diversity of root-associated fungi. In conclusion, the fungal community structure is similar within the same region, while significant differences exist in the taxonomic structure and biodiversity among different regions. These findings shed light on the intricate interplay and mechanisms governing the ecological restoration of , offering a valuable framework for advancing green ecology initiatives and harnessing the potential of root-associated microorganisms in this species.
罗氏亚种（缩写）是改善中国西北干旱地区生态景观的重要植物资源，其根际微生物是其生长发育动态的关键因素。本研究旨在探讨[该植物名称]根内生真菌的群落结构特征和起源差异。从西北地区沿海拔梯度自然分布[该植物名称]的25个区域采集样本。然后，采用高通量测序技术分析不同区域的内生真菌，比较内生真菌的结构特征，并研究它们与环境因素的关系。利用FUNGuild分析内生真菌的群落结构和功能，结果表明每个区域都有自己的优势内生真菌菌群，表明内生真菌起源存在差异，[该植物名称]生长季节从原始土壤中获得的特定内生菌群将有助于我们构建微生态群落结构。此外，该研究鉴定并评估了真菌的多样性，阐明了物种结构并突出了优势物种。冗余分析（RDA）表明，有效磷（AP）、有效钾（AK）和总氮（TN）与根际真菌的组成和多样性显著相关。总之，同一区域内真菌群落结构相似，不同区域间分类结构和生物多样性存在显著差异。这些发现揭示了[该植物名称]生态恢复的复杂相互作用和机制，为推进绿色生态倡议和挖掘该物种根际微生物的潜力提供了有价值的框架。
