DC., the largest genus of Papaveraceae, was recognized as one of the most taxonomically challenging plant taxa. Due to the lack of genetic information used in previous studies, species discrimination and taxonomic assignment in have not been fully solved. Here, the complete chloroplast genomes were reported for Maxim. and Liden, with their genome sizes being 154,395 and 155,938 bp, respectively. Both of the chloroplast genomes comprise two inverted repeat (IR) regions, separated by a large single-copy (LSC) region and a small single-copy (SSC) region, and encode 130 genes, including 85 protein-coding genes, 8 ribosomal RNA genes, 37 transfer RNA genes. Our study will provide novel insight into the molecular phylogeny and classification of .
紫堇属是罂粟科最大的属，被认为是分类学上最具挑战性的植物类群之一。由于以往研究中缺乏遗传信息，紫堇属的物种鉴别和分类归属尚未得到充分解决。在此，报道了全叶延胡索和长距紫堇的完整叶绿体基因组，其基因组大小分别为154,395和155,938碱基对。两个叶绿体基因组均由两个反向重复（IR）区域组成，被一个大单拷贝（LSC）区域和一个小单拷贝（SSC）区域隔开，并编码130个基因，包括85个蛋白质编码基因、8个核糖体RNA基因、37个转运RNA基因。我们的研究将为紫堇属的分子系统发育和分类提供新的见解。
