Abstract

Dicliptera tinctoria is a member of Acanthaceae, which has a wide distribution and contains potentially medicinal species, and exhibited pharmaceutical potentials. This study sequenced and characterized the complete chloroplast genome of Dicliptera tinctoria. The newly sequenced cpDNA of D. tinctoria was 150,733 bp in length and had a typical quadripartite structure consisting of a large single copy (LSC, 82,895 bp), a small single copy (SSC, 17,249 bp), and two inverted repeat (IRs, 25,295 bp each) regions. This genome also contained 80 protein-coding genes, 30 transfer RNAs, and four ribosomal RNAs, which is identical to other chloroplast genomes in Acanthaceae family. Nucleotides diversity analysis among chloroplast genomes of Acanthaceae species revealed eight hypervariable regions, including trnK_UUU-matK, trnC_GCA-petN, accD, rps12-clpP, rps3-rps19, ycf1-ndhF, ccsA-ndhD, and ycf1. Phylogenetic analysis revealed the paraphyly of Dicliptera species and monophyly in four Acanthaceae subfamilies. These results provide an overview of genomic variations in Acanthaceae chloroplast genome, which is helpful for further genomic studies.

Dicliptera tinctoria (Nees) Kostel.的完整叶绿体基因组以及刺桐科植物叶绿体基因组的比较分析。

Dicliptera tinctoria 是刺桐科植物，分布广泛，含有潜在的药用物种，具有制药潜力。本研究对 Dicliptera tinctoria 的完整叶绿体基因组进行了测序和鉴定。新测序的 D. tinctoria cpDNA 长度为 150,733 bp，具有典型的四方结构，包括一个大的单拷贝（LSC，82,895 bp）、一个小的单拷贝（SSC，17,249 bp）和两个反向重复区（IR，各 25,295 bp）。该基因组还包含 80 个蛋白质编码基因、30 个转移 RNA 和 4 个核糖体 RNA，与刺桐科其他叶绿体基因组相同。对刺桐科植物叶绿体基因组的核苷酸多样性分析发现了8个高变异区，包括trnK_UUU-matK、trnC_GCA-petN、accD、rps12-clpP、rps3-rps19、ycf1-ndhF、ccsa-ndhD和ycf1。系统进化分析表明 Dicliptera 物种为旁系，在四个刺桐亚科中为单系。这些结果提供了刺桐科叶绿体基因组变异的概况，有助于进一步的基因组研究。
