锁阳是分布于荒漠生态系统中的一种罕见的根寄生植物。关于内生菌在C. songaricum。在此基础上，研究了七种活性成分（总糖、黄酮、原儿茶酸、儿茶素、单宁、没食子酸和熊果酸）与内生真菌的相关性。并对它们之间的因果关系作了进一步的讨论。结果表明，这些成分的积累和内生真菌的组装随植物发育阶段的不同而变化。相关系数矩阵分析表明，化学物质与内生真菌操作分类单元之间存在着正相关和负相关的多样性，说明内生真菌次生代谢产物的积累与内生真菌操作分类单元之间的关系密切。与内生真菌群落组成密切相关。这些结果提供了新的机会，深入了解植物真菌共生和次生代谢产物的生产。
Cynomorium songaricum Rupr. is a rare root-parasitic plant distributed in the desert ecosystem. Little is known about the role of endophytes in accumulation of metabolites in C. songaricum. Here, the correlations between the seven active components (total sugars, flavonoids, protocatechuic acid, catechins, tannins, gallic acid, and ursolic acid) and the endophytic fungi of C. songaricum were investigated, and their causal relationships are discussed further. The results showed that the accumulation of these components and the assembly of endophytic fungi changed with different plant developmental stages. Diverse relationships including positive and negative correlation were found among chemicals and endophytic fungal operational taxonomic units based on correlation coefficient matrices, which demonstrated that the accumulation of secondary metabolites in C. songaricum is closely related to the endophytic fungal community composition. These results present new opportunities to deeply understand plant-fungal symbioses and secondary metabolite productions.
