Thus, the molecular techniques are becoming more popular in the differentiation of Microcystis.16S rDNA, 16S-23S rDNA ITS and PC-IGS have been used in phylogenic classification of Microcystis, they are common molecular markers of taxonomic researches and a number of results have been carried out.

利用分子生物学技术鉴定微囊藻的种属具有快速而且可靠的优势，因此已成为了分类研究的新趋势。16S rDNA、16S-23S rDNA ITS、PC-IGS等基因序列在微囊藻的分子系统发育方面已有一些研究结果，是目前分类学研究较常用的分子标记，但各自仍存在了一定的问题。

The universal primers of ITS1 and ITS4 for fungi were used in amplification of genomic rDNA sequences. A target fragment was obtained by ITS-PCR. Then, the fragment is cloned into the vector of pMD18-T before sequencing. The result of sequencing showed that the fragment is 692 bp in length. The results of Blast in Genbank and the analysis of fungal rDNA systemic development show that the relation between this fragment to the fungi of Sporisorium is closest, while the relation between it to the fungi of Ustilago is much far. It suggests that the name of Ustilago scitaminea for sugarcane smut isn't consistent to the result of rDNA systemic development analysis. It still needs more experiments to support this hypothesis.

用真菌rDNA序列分析的通用引物ITS1和ITS4，通过ITS-PCR得到目的片段，克隆在pMD18-T载体上后进行测序，结果显示该片段的长度为692 bp，与Genebank中已报道的真菌序列进行Blast和系统发育树分析，表明所获得的序列与Sporisorium属真菌具有更高的亲缘关系，而与Ustilago属真菌的亲缘关系较远，这与一直沿用的甘蔗黑穗病菌的命名似乎并不吻合，有待进行更多的研究以证实。
