摘  要：
本研究利用β-tub2,ef1-α和his4基因部分序列对60株采自云南省不同葡萄产区的葡萄炭疽病菌菌株进行基因谱系分析。结果表明:引起云南葡萄炭疽病的病原菌种类较为复杂,不仅包括胶孢炭疽菌复合种群中的Colletotrichum gloeosporioides,还有胶孢炭疽菌复合种群中的其他种或炭疽菌属其他种。来源于不同产地不同葡萄品种上的炭疽菌遗传多样性丰富,但分子水平的多样性与菌株的地理来源、寄主种类、形态特征及对红提致病力方面无明显相关性。

摘  要：
The genetic diversity of 60 Colletotrichum spp. isolates collected from main grape-growing areas in Yunnan was characterized with the molecular phylogenetic tree of β-tub2,ef1-α,and his4 partial gene sequence. The results indicated that grape anthracnose was caused not only by Colletotrichum gloeosporioides,but also by other species within the C. gloeosporioides complex,and other species in Colletotrichum. Further analysis demonstrated that there was rich genetic diversity level within the population isolated from different grape specificities coming from different areas in Yunnan. However,the genetic diversity of these isolates had no correlation with those characterizations including geographic origins,host specificities,colony or spore morphologies and pathogenicity to red globe grape.
