比较了马尾藻科两种马尾藻属植物核糖体DNA内部转录间隔区2 （ITS‐2）的序列。利用马尾藻不同亚属和不同剖面的种，对其属内的分类关系进行了评价，特别是对小芽藻亚属的分类关系进行了评价。序列按照它们共同的二级结构排列。采用邻居连接法、最大似然法和最大简约法，以三种涡虫为外群，构建了系统发育树。
Sequences from the ribosomal DNA internal transcribed spacer‐2 (ITS‐2) were compared among species of Sargassaceae including the genera Sargassum and Hizikia. Species of different subgenera and sections of Sargassum were used to assess the taxonomic relationships within the genus, especially the subdivisions of the subgenus Bactrophycus. Sequences were aligned in accordance with their common secondary structure. Phylogenetic trees were constructed using neighbor‐joining, maximum likelihood and maximum parsimony methods with three species of Turbinaria as outgroups.
