茶树内生真菌研究进展

Research Progress on Endophytic Fungi of Camellia sinensis

茶树(Camellia sinensis)内生真菌是重要的微生物资源,具有重大的研究和开发价值。目前已分离鉴定的茶树内生真菌主要类群有刺盘孢菌(Colletotrichum)、拟盘多毛孢(Pestalotiopsis)、球座菌(Guignardia)、拟茎点霉(Phomopsis)、大茎点霉(Macrophoma.)、曲霉(Aspergillu)、木霉(Trichoderma)、青霉(Penicillium)、链格孢霉(Alternaria)、镰孢霉(Fusarium)等。茶树内生真菌的种类和数量因茶树品种、茶树不同部位、生长期、季节和环境的变化明显不同。内生真菌能改变茶叶的化学成分,促进茶树生长,产生具有抗菌作用的次级代谢产物。对近年来茶树内生真菌的研究进展进行了简要综述。

Endophytic fungi are important microbial resources which deserved to be researched and exploited. The reported endophytic fungi of tea are mainly Colletotrichum, Pestalotiopsis, Guignardia, Phomopsis, Macropho, Aspergillu, Trichoderma, Penicillium, Alternaria and Fusarium. The species and the quantity of endophytic fungi always varies with different tea varieties, parts, growth period, seasons and environments. Endophytic fungi can change the chemical component of tea, promote the growth of tea bushes, product secondary metabolites with antibacterial function. In this paper, the research advances on endophytic fungi of tea were reviewed.
