The complete mitochondrial genome of () was reported in this study. The mitochondrial genome (mitogenome) was assembled to 271 618 nt. The mitogenome contains 31 protein-coding genes, three rRNA genes and 16 tRNAs. The overall base composition of the mitogenome in descending order is A: 27.21%, C: 22.61%, G: 22.78% and T: 27.40%, and the G + C content is 45.39%. Additionally, 30 exons and 17 introns were identified in eight genes and nine tandem repeats were identified with the period size from 10 nt to 33 nt. Phylogenetic analysis shows that the genome is evolutionarily closest to that of Lotus japonicas. With the complete mitogenome of , it is beneficial to the further research of mitogenome of seed plants, and especially helpful for elucidating vital activities of legumes.
本研究报道了()的完整线粒体基因组。线粒体基因组(有丝分裂基因组)组装后为271618个核苷酸。该有丝分裂基因组包含31个蛋白质编码基因、3个rRNA基因和16个tRNA。有丝分裂基因组的总体碱基组成由高到低依次为:A:27.21%,C:22.61%,G:22.78%,T:27.40%,G + C含量为45.39%。此外,在8个基因中鉴定出30个外显子和17个内含子,并鉴定出9个串联重复序列,其周期大小为10个核苷酸至33个核苷酸。系统发育分析表明,该基因组在进化上与日本百脉根的基因组最为接近。有了()的完整有丝分裂基因组,有利于对种子植物有丝分裂基因组的进一步研究,尤其有助于阐明豆科植物的生命活动。
