用16种限制性内切酶对日本产紫菀属18种、马兰属6种、宫山苗属2种和狗娃花属1种1变种植物的cpDNA进行了RFLPs分析，共检测到275个酶切位点，共检测到74个酶切位点突变，其中31个位点具有遗传学信息。通过瓦格纳简约分析构建了16棵最简约树，表明马兰属和Miyamayomena sensu Kitamura; miqueliana与Kalimeris的其余物种属于不同的分支，Miyamayomena的两个物种没有形成单一的分支。这一结果表明冠毛的缩短或消失在不同的进化谱系中是交替发生的。我们必须仔细评估冠毛的特征在分类学和系统发育，这是可取的，以检查它们的系统发育关系使用的分子数据。
RFLPs of cpDNA were examined for 18 species of Aster, six species of Kalimeris, two species of Miyamayomena and one species and one variety of Heteropappus from Japan, using 16 restriction endonucleases, Approximately 275 restriction sites were surveyed, and a total of 74 restriction site mutations was detected, and 31 of these were phylogenetically informative. Sixteen most parsimonious trees constructed from Wagner parsimony analysis indicated the polyphyly of Kalimeris and Miyamayomena sensu Kitamura; K. miqueliana belongs to a different clade from the remaining species of Kalimeris, and two species of Miyamayomena did not make a single clads. This result suggests that the shortening or loss of pappus have happened parallelly in different evolutionary lineages. We must be careful to assess the pappus character in taxonomy and phylogeny, and it is desirable to examine their phylogenetic relationships using a molecular data.
