| 摘 要： | 橡胶树炭疽病是橡胶树上一种重要叶部病害,已知病原菌有胶孢炭疽菌和尖孢炭疽菌,它们是复合种群,群下种类多,遗传多样性丰富。利用ITS、GAPDH、CHS-1和ACT基因的部分序列,对来自海南省橡胶树不同植胶地点的16株炭疽菌,进行基因谱系比较分析。结果显示,采用单基因部分序列和4基因拼接序列都能将供试菌株分为两大类群:胶孢炭疽菌复合群和尖孢炭疽菌复合群。其中,来自于儋州HN06、乐东志仲HN02和保亭大本HN16的3个菌株聚类于尖孢炭疽菌复合群,其余13个菌株聚类于胶孢炭疽菌复合群。4基因拼接序列分析还可以看出,胶孢炭疽菌复合群下参试的9个菌株都属于分支Musae Clade。但是采用单基因或4基因拼接序列均不能将海南橡胶炭疽菌鉴定到复合群下的具体种。
