摘  要：
对分离自海南4个地区13种寄主植物上暹罗炭疽菌的ITS-CAL-GAPDH 3基因序列进行群体遗传结构分析。95条暹罗炭疽菌多基因序列可定义为16个单倍型,其中,单倍型H5为主要单倍型,分布于所有寄主植物。AMOVA分析显示,遗传变异主要发生在种群内;病菌未经历过大规模的种群扩张过程。研究结果表明,暹罗炭疽菌种群具有丰富的遗传多样性。

摘  要：
Anthracnose pathogen can caus e worldwide anthracnose to many plants. The paper presents the population genetic structure of C. siamense strains isolating from thirteen host plants growing in four regions of Hainan. 95 ITS-CAL-GAPDH gene sequences of C. siamense could be defined as 16 haplotypes. And the major haplotypes H5 was found in the thirteen hosts. AMOVA analysis showed that the genetic variation mainly took place within the population. And the pathogen didn't experience large-scale population expansion. The results showed that the C. siamense natural population had rich genetic diversity.
