摘要: 从福建地区不同品种茶树上分离获得ZHG、WSX、WHG、FTG、ZTG、AHD、WRG、SLH等8株能侵染茶树的病原菌,采用形态学和rDNA-ITS序列分析相结合的方法对其进行鉴定。结果发现,SLH菌株为胶孢炭疽菌Colletotrichum gloeosporioides,其余7个菌株均为Colletotrichum fructicolaC. fructicola为能侵染茶树的新记录种炭疽菌,将其ITS序列与寄主分别为油茶、茉莉和番石榴等木本植物的9株炭疽菌的ITS序列进行聚类分析,结果显示,来自茶树的7个C. fructicola菌株种内存在碱基突变或缺失,且与寄主为茶树、油茶、茉莉等植物的胶孢炭疽菌C. gloeosporioides遗传距离较近。

Abstract: Eight strains of anthracnose pathogen, ZHG, WSX, ZTG, WHG, FTG, AHD, WRG and SLH were isolated from different tea cultivars in Fujian Province. These strains were identified by using morphological method and rDNA-ITS sequence analysis. The results showed that SLH strain was identified as Colletotrichum gloeosporioides, while the other seven strains were Colletotrichum fructicola, which has never been discovered on tea plant. The ITS sequences of C. fructicola and those of nine strains of anthracnose pathogen from tea-oil tree, jasmine plant and papaya (psidium guajave), were got for a clustering analysis. The results showed that base mutations or deletions were existed in the seven strains from tea plant, and the seven strains of C. fructicola were geneticly close to the pathogen C. gloeosporioides, isolated from tea plant, oil-tea plant and jasmine plant.
