is a tertiary relict evergreen broad-leaf shrub in family Fabaceae with remarkable tolerance to desiccation and low temperature. In this study, we report the complete mitochondrial genome of The total genome length was 475,396 bp and contained a total of 127 genes, including 79 protein-coding genes (28 novel genes, 45 known functional genes, and six known orf genes), three rRNA genes, and 45 tRNA genes. Most of the genes were single-copy genes, only six were duplicated and two were multi-copy. The mitochondrial genome also contained 'promiscuous' sequences from the chloroplast, 16 intact tRNAs of mitochondrial origin, and 29 intact and potentially functional chloroplast-derived tRNAs. The overall GC content of the mitochondrial DNA was 42.75%. A neighbour-joining phylogenomic analysis showed that was closely related to , which also belongs to family Leguminosae.
是豆科的一种第三纪残遗常绿阔叶灌木，对干旱和低温具有显著耐受性。在本研究中，我们报道了 的完整线粒体基因组。基因组全长475,396 bp，共包含127个基因，其中包括79个蛋白质编码基因（28个新基因、45个已知功能基因和6个已知的orf基因）、3个rRNA基因和45个tRNA基因。大多数基因是单拷贝基因，只有6个是重复的，2个是多拷贝的。线粒体基因组还包含来自叶绿体的“混杂”序列、16个线粒体来源的完整tRNA以及29个完整且可能具有功能的叶绿体来源的tRNA。线粒体DNA的总体GC含量为42.75%。邻接法系统发育基因组分析表明， 与同样属于豆科的 密切相关。
