摘要
亚种 Abrus pulchellus subsp. mollis 具有类似于中国传统药用植物阿胶的药理特性。在本报告中,我们揭示了 A. pulchellus subsp.该基因组跨度为 156,322 碱基对(bp),包括一个长达 86,633 bp 的大型单拷贝(LSC)区、一个长达 18,219 bp 的小型单拷贝(SSC)区以及两个各长达 25,735 bp 的不同倒位重复区(IR)。注释过程共对该基因组中的 111 个基因进行了编目,包括 77 个蛋白质编码基因、30 个转运 RNA(tRNA)基因和 4 个核糖体 RNA(rRNA)基因。质粒体的鸟嘌呤-胞嘧啶(GC)总含量为 35.5%。利用基于 16 个完整质体基因组的最大似然法(ML)进行的系统发生分析表明,Abrus 的三个类群(即 A. pulchellus subsp.值得注意的是,A. pulchellus subsp. cantoniensis 与 A. precatorius 聚类为姊妹群,有别于 A. pulchellus subsp.这些发现突显了这两个亚种质粒基因组之间的显著差异,为今后鉴定这些亚种相关药材和种质资源的研究奠定了基础。
The complete plastid genome of Abrus pulchellus subsp. mollis (Leguminosae): a medicinal plant in Southern China.
The subspecies Abrus pulchellus subsp. mollis exhibits pharmacological properties akin to the traditional Chinese medicinal plant Abri Herba (A. pulchellus subsp. cantoniensis (Hance) Verdc.). In this report, we unveil the plastid genome of A. pulchellus subsp. mollis. The genome spans 156,322 base pairs (bp), comprising a large single-copy (LSC) region of 86,633 bp, a small single-copy (SSC) region of 18,219 bp, and two distinct inverted repeat regions (IRs) of 25,735 bp each. Annotation process cataloged a total of 111 genes within this genome, including 77 protein-coding genes, 30 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. The overall guanine-cytosine (GC) content of the plastome is 35.5%. Phylogenetic analysis utilizing maximum-likelihood (ML) based on 16 complete plastid genomes reveals a close clustering of three Abrus taxa, namely A. pulchellus subsp. mollis, A. pulchellus subsp. cantoniensis, and A. precatorius. Notably, A. pulchellus subsp. cantoniensis clusters with A. precatorius as a sister group, distinct from A. pulchellus subsp. mollis. These findings highlight significant differences between the plastid genomes of the two subspecies, laying the foundation for future research on the identification of medicinal herbs and germplasm resources related to these subspecies.
