The genetic diversity of Ganoderma australe (Fr.) Pat. from southern India was investigated by using ITS1/2 rDNA. The phylogenetic analysis showed that six isolates clustered into two groups viz. biological species I and II. The four strains of BS I (YER03, MYC5, MYC2 and KE) clustered with G. australe TAI-01 and the two other strains of BS II (KMK3 and K39) were grouped with G. australe TAI-05 from Taiwan. The two strains namely TAI-01 and TAI-05 were described as G. australe intersterile Group 1 and 2 from Taiwan, respectively. The higher level nucleotide divergence among BS I and BS II and the high bootstrapping support clearly represent the presence of two biological species of G. australe in southern India which are genetically isolated.
利用ITS1/2 rDNA对来自印度南部的南方灵芝（Ganoderma australe (Fr.) Pat.）的遗传多样性进行了研究。系统发育分析表明，六个分离株聚为两组，即生物种I和生物种II。生物种I的四个菌株（YER03、MYC5、MYC2和KE）与南方灵芝TAI-01聚类，生物种II的另外两个菌株（KMK3和K39）与来自台湾的南方灵芝TAI-05归为一组。菌株TAI-01和TAI-05分别被描述为来自台湾的南方灵芝不育组1和不育组2。生物种I和生物种II之间较高水平的核苷酸差异以及较高的自展支持率清楚地表明，在印度南部存在两种遗传隔离的南方灵芝生物种。
