系统发育分类

在Epistylis属纤毛虫中，柄的中空与否是一个有用的系统发育和分类特征。

The hollow nature of the stalk is a useful phylogenetic and taxonomic character in the genus Epistylis .

由于rDNA序列兼具保守区域和进化水平不同所致可变区，因此，rDNA序列分析是研究真菌系统发育、分类鉴定和分子检测非常有效的手段。

With the conservative regions and variable regions in rDNA gene sequences , the analysis of rDNA sequences is very efficient in research of fungi systemic development , classification identification and molecular detection . The method of single spore isolation is occupied in this experiments .
