摘要:

为了解茶树响应炭疽病及抗炭疽病的遗传机理，本研究搜集了茶树炭疽病的发病规律与症状、茶树炭疽病原菌分类鉴定、炭疽菌侵染过程及其机制等在茶树上的研究成果，并结合其他植物上的相关报道进行总结。结果发现：茶树炭疽病致病菌多样，侵染致病过程复杂，导致致病菌鉴定困难。同时，茶树致病菌的侵染分子机制研究较少，在其它植物中主要与真菌代谢酶类、效应蛋白及真菌毒素等有关，但具体完整的分子调控机制仍不明确。后续需继续对侵染机制和寄主茶树-炭疽病原菌互作机制进行研究，加强田间病害检测技术的研究与推广，以期为茶树炭疽病的发病机制及早期判断、综合防治提供有效帮助。

Abstract:

To understand the genetic mechanism of response and resistance to anthracnose of tea plant， this study collected and summarized the progress on the pathogenesis and symptoms of tea plant anthracnose， the classification and identification of tea plant anthracnose pathogens， the infection process and mechanism of anthracnose， combined with the related reports on other plants. The results showed that： The pathogenic fungi of tea anthracnose were diverse and the infection process was very complicated， which resulted in difficult to identification of pathogenic fungi. Meanwhile， there were few studies on the molecular mechanism of infection to tea plants. However， existing studies were mainly related to fungal metabolic enzymes， effector proteins and mycotoxins in other plants， the molecular regulatory mechanism was still unclear. It is necessary to further study the infection mechanism and the interaction between host tea plant and anthracnose pathogens， and strengthen the field disease detection technology， so as to provide effective help for the infection regulation and its early diagnose， and comprehensive control of tea anthracnose.
