The classification system and evolutionary history of Erysiphaceae have been studied based on the results of molecular phylogenetic analyses. However, the sequence data used for these phylogenetic estimations have been limited to the nrDNA of ca., 50 taxa, and the relationships among higher taxonomic groups are not well understood. To provide a phylogenetic overview of Erysiphaceae, we performed phylogenetic estimations based on nrDNA and MCM7 sequences obtained from ca., 270 taxa. The phylogenetic tree showed a similar topology to the trees obtained in previous studies, although the branching order between Golovinomyceteae and Phyllactinieae was different and Phyllactinieae was not monophyletic. Phyllactinieae and Erysipheae were estimated to diversify after the divergence of Golovinomyceteae, suggesting an evolutionary trend in which non-catenate conidia + endoparasitic or non-catenate conidia + ectoparasitic lineages were derived from catenate conidia + ectoparasitic lineages. Phyllactinieae was divided into a clade of Phyllactinia + Leveillula and other clade(s) consisting of Pleochaeta and Queirozia. The phylogenetic hypothesis of Erysiphaceae was updated based on the largest dataset to date, but the higher-level phylogenetic relationships remain unclear. For a more robust phylogenetic hypothesis of Erysiphaceae, further sequence data, including protein coding regions, should be added to the dataset of nrDNA sequences.

基于分子系统发育分析结果，研究了菊科的分类系统和进化史。但是，用于这些系统发育估计的序列数据仅限于大约50个分类单元的nrDNA，并且对较高分类组之间的关系还不太了解。为了提供菊科的系统发育概述，我们基于nrDNA和MCM7进行了系统发育评估。从大约270个分类单元中获得的序列。尽管Golovinomyceteae和Phyllactinieae之间的分支顺序不同且Phyllactinieae不是单系的，但系统发育树显示出与先前研究中获得的树相似的拓扑。毛细支孢菌的发散后，估计叶菌科和赤藓科会多样化，这表明进化趋势是非门生分生孢子+内寄生或非门生分生孢子+胞外寄生谱系来自门生分生孢子+外寄生谱系。Phyllactinieae分成的进化枝Phyllactinia  + 白粉病和其它进化枝（S）组成的Pleochaeta和Queirozia。迄今为止，基于最大的数据集更新了菊科的系统发育假说，但高层系统发育关系尚不清楚。对于更强壮的菊科系统发育假说，应将进一步的序列数据（包括蛋白质编码区）添加到nrDNA序列数据集中。
