is an ornamental flowering plant belonging to the family Campanulaceae. The complete chloroplast genome of was obtained using Illumina HiSeq X and Oxford Nanopore (Nanopore GridION) platforms. The chloroplast genome exhibited a typical circular structure with a total length of 169,341 bp, comprising a large single-copy region of 102,323 bp, a small single-copy region of 7744 bp, and a pair of inverted repeats (IRa/IRb) of 29,637 bp each. Out of a total 120 genes, 76 were protein-coding genes, 36 were transfer RNA genes, and eight were ribosomal RNA genes. The genomic characteristics of are similar to those of other species in terms of repetitive sequences, sequence divergence, and contraction/expansion events in the inverted repeat regions. A phylogenetic analysis of 63 shared genes in 16 plant species revealed that is the closest relative of . Phylogenetic analysis indicated that was within the clade, and occupied the outermost position of that clade.
是桔梗科的一种观赏花卉植物。通过 Illumina HiSeq X 和 Oxford Nanopore (Nanopore GridION) 平台获得了 的完整叶绿体基因组。叶绿体基因组呈现出典型的圆形结构，总长度为 169341bp，包括一个长为 102323bp 的大单拷贝区、一个长为 7744bp 的小单拷贝区和一对长为 29637bp 的反向重复区（IRa/IRb）。在总共 120 个基因中，76 个是蛋白质编码基因，36 个是转移 RNA 基因，8 个是核糖体 RNA 基因。 的基因组特征与其他 物种在重复序列、序列差异以及反向重复区的收缩/扩张事件方面相似。对 16 种植物物种的 63 个共享基因进行的系统发育分析表明， 与 最为接近。系统发育分析表明 位于 分支内，而 占据该分支的最外侧位置。
