This study was focus on investigating the community composition of endophytic fungi in the leaves of Vaccinium dunalianum Wight. Based on a combination of morphological features and molecular evidence, 239 endophytic fungal isolates belonging to 33 genera including 62 species were obtained and identified. By comparing the relative abundance (RA) values, the most frequent species belonged to Phyllosticta and Guignardia with RA of 26·78 and 14·22% respectively. Of which, the strains P. capitalensis and G. mangiferae with potential antimicrobial activity were the dominant endophytes to the sampling of leaves. A high diversity of endophytic fungi from V. dunalianum leaves was observed with high species richness S (62), Margalef index D′ (11·1386), Shannon–Wiener index H′ (3·2588), Simpson's diversity index Ds (0·9179), probability of interspecific encounter index (0·9218), and evenness Pielou index J (0·7896) but a low dominant index λ (0·0821).

杜氏牛痘叶片内生真菌的多样性

本研究的重点是调查牛痘(Vaccinium dunalianum Wight)叶片内生真菌群落组成。结合形态特征和分子证据，共获得并鉴定出内生真菌239株，分属33属62种。通过比较相对丰度(RA)值，最常见的物种属于Phyllosticta和Guignardia，RA分别为26·78和14·22%。其中，具有潜在抗菌活性的P. capitalensis和G. mangiferae菌株是叶片取样的优势内生菌。观察到来自 V. dunalianum 叶内生真菌的高度多样性，具有高物种丰富度 S (62)、Margalef 指数 D' (11·1386)、Shannon-Wiener 指数 H' (3·2588)、Simpson's 多样性指数 Ds (0 ·9179),
