Abstract

Endophytes confer fitness advantages to host plants. However, the ecological communities of endophytic fungi in the different tissues (rhizomes, stems, and leaves) of Paris polyphylla and the relationship of their endophytic fungi with polyphyllin levels remain unclear. In this study, the community diversity and differences of endophytic fungi in the rhizomes, stems, and leaves of P. polyphylla var. yunnanensis were investigated, and a comprehensively diverse community of endophytic fungi was represented, including 50 genera, 44 families, 30 orders, 12 classes, and 5 phyla. Distributions of endophytic fungi differed greatly across the three tissues, with six genera common to all tissues, and 11, 5, and 4 genera specific to the rhizomes, stems, and leaves, respectively. Seven genera showed a significantly positive correlation to polyphyllin contents, indicating their potential roles in polyphyllin accumulation. This study provides valuable information for further research of the ecological and biological functions of endophytic fungi of P. polyphylla.

云南多叶桦内生真菌多样性及其与多叶桦素水平相关性的新认识。

内生植物赋予寄主植物适应性优势。然而，对多叶莲不同组织(根状茎、茎和叶)中内生真菌的生态群落及其与多叶莲素水平的关系尚不清楚。本研究对云南多叶P. polyphylla var. yunnan的根状茎、茎、叶内生真菌的群落多样性及差异进行了研究，初步建立了一个包括44科30目12纲5门50属的综合多样性的内生真菌群落。内生真菌在三种组织中的分布差异很大，所有组织共有6个属，根状茎、茎和叶分别有11个、5个和4个属。7个属与多叶树素含量呈极显著正相关，提示它们在多叶树素积累中可能发挥作用。本研究为进一步研究多叶内生真菌的生态生物学功能提供了有价值的信息。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
