我们制作了完整的序列，并进行了比较分析的母系遗传的叶绿体（CP）基因组和双亲遗传的45 S核核糖体RNA基因（nrDNA）从10个五加科物种，以阐明该家庭的遗传多样性和进化。CP基因组长度为155，993 ~ 156，730 bp，同源性为97.1-99.6%。完整的45 S nrDNA单位约为11 kb，包括一个5.8kb的45 S顺反子。在79个编码cp蛋白的基因中，74个基因在10个物种间存在核苷酸变异，其中infA、rp 122、rps 19和ndhE基因的Ks值最高，atpF、atpE、ycf 2和rps 15基因的Ka/Ks值最高。四个基因，petN，psaJ，psbF和psbN，光合作用和一个基因，rpl 23，核糖体大亚基相关的仍然保守在所有10个五加科物种。系统发育分析显示，这10个物种可以分为两个单系谱系，Panax-Aralia和Eleutherococcus-Dendropanax组，它们在大约881 - 1059万年前（MYA）分化。人参属分为两个组，二倍体物种包括三七、越南人参和生活在南亚的人参，四倍体物种包括人参和西洋参，分布于北方亚洲和北美，距今289 - 320百万年。
We produced complete sequences and conducted comparative analysis of the maternally inherited chloroplast (cp) genomes and bi-parentally inherited 45S nuclear ribosomal RNA genes (nrDNA) from ten Araliaceae species to elucidate the genetic diversity and evolution in that family. The cp genomes ranged from 155,993 bp to 156,730 bp with 97.1–99.6% similarity. Complete 45S nrDNA units were about 11 kb including a 5.8-kb 45S cistron. Among 79 cp protein-coding genes, 74 showed nucleotide variations among ten species, of which infA, rpl22, rps19 and ndhE genes showed the highest Ks values and atpF, atpE, ycf2 and rps15 genes showed the highest Ka/Ks values. Four genes, petN, psaJ, psbF, and psbN, related to photosynthesis and one gene, rpl23, related to the ribosomal large subunit remain conserved in all 10 Araliaceae species. Phylogenetic analysis revealed that the ten species could be resolved into two monophyletic lineages, the Panax-Aralia and the Eleutherococcus-Dendropanax groups, which diverged approximately 8.81–10.59 million years ago (MYA). The Panax genus divided into two groups, with diploid species including P. notoginseng, P. vietnamensis, and P. japonicus surviving in Southern Asia and a tetraploid group including P. ginseng and P. quinquefolius Northern Asia and North America 2.89–3.20 MYA.
