The recent massive development in the next-generation sequencing (NGS) platforms and bioinformatics tools including cloud-based NGS data analyses have proven extremely useful in understanding the deeper-level phylogenetic relationships of angiosperms. The family ‘Apiaceae Lindley / Umbelliferae Jussieu’ and Araliaceae Jussieu resemble each other in the structure of their gynoecia, were placed in the order Apiales Nakai, and are closely related. The family Araliaceae with the subfamily 1. Hydrocotyloideae Link, 2. Harmsiopanax Harms and 3. Aralioideae Eaton accepted as a monophyletic branch within the Apiales, an order within the Asterids. Of these, Hydrocotyle L. from Hydrocotyloideae Link of Apiaceae transferred to Araliaceae based on molecular phylogenetic studies. The present study evaluates the proximity of H. umbellata with Araliaceae based on plastome and phylotranscriptomic analyses using the minimum evolution method. The analyses revealed the nesting of the H. umbellata under the family Araliaceae in the MPT (Maximum Parsimony Tree), and the proximity of H. umbellata under the family Araliaceae further supported by the evolutionary divergence between the sequences and plastome alignment.

新一代测序（NGS）平台和包括基于云的NGS数据分析在内的生物信息学工具的最新发展已证明对理解被子植物的深层次系统发育关系极为有用。'Apiaceae Lindley / Umbelliferae Jussieu '和Araliaceae Jussieu的妇科结构彼此相似，按照Apiales Nakai的顺序排列，并且密切相关。Araliaceae科及其亚科1. Hydrocotyloideae Link，2。Harmsiopanax Harms和3. Aralioideae Eaton被接受为Apiales内的单系统分支，属于紫杉类。其中，天胡荽L.从Hydrocotyloideae基于分子系统发育研究，将伞形科的链接转移到了伞形科。本研究基于质子组和系统转录组学分析，使用最小进化方法评估伞形科与伞形科的亲缘关系。分析揭示了伞形目H. umbellata在MPT（最大简约树）下的嵌套，而伞形目H. umbellata在伞形目下的接近进一步得到了序列之间的进化差异和质体组比对的支持。
