从我国南方著名栽培蓝莓杜鹃花科(Ericaceae)中分离得到内生真菌374株。根据培养特征和基于内部转录间隔区的分子鉴定，这些真菌内生菌可分为25种形态型。所有这些分离株都属于子囊菌门。杰卡德（Jc）和索伦森相似指数表明，果实和枝条的物种群落彼此比叶子的物种群落更接近。叶子似乎具有最高的真菌多样性，而果实则表现出最低的多样性。这项研究的意义和影响这项研究是第一个从蓝莓植物的果实、树枝和叶子中分离出的内生真菌的研究。这些结果有助于建立与蓝莓相关的病原体生物防治的知识体系，并促进植物生长的改善。通过与不同的真菌群落进行比较，叶子似乎拥有最高的生物多样性。
A total of 374 fungal endophyte strains were isolated from ofVaccinium dunalianumvar.urophyllum(Ericaceae), a well‐known cultivated blueberry in southern China. These fungal endophytes could be categorized into 25 morphotypes according to culture characteristics and molecular identification based on the internal transcribed spacer region. All of these isolates belonged to Ascomycota. Jaccard's (Jc) and Sorenson's similarity indices indicated that the species communities from the fruits and branches were closer to each other than to those from leaves. The leaves appeared to host the highest fungal biodiversity, and the fruits displayed the lowest diversity.Significance and Impact of the StudyThis study is the first on endophytic fungi isolated from fruits, branches and leaves of blueberry plants. The results contribute to the body of knowledge on the biocontrol of pathogens associated with blueberry and develop the improvement of plant growth. By comparing with the different fungal communities, the leaves appeared to host the highest biodiversity.
