In this project, we studied the complete mitogenome of the liliaceae medicinal plant Polygonatum sibiricum. The genome is represented by a circular ring molecule with a length of 691,910 bp and a GC content of 46.33%. Mitochondrial genome composition is slightly biased towards A+T, with AT accounting for 53.67%, and AT skewness slightly positive (0.092%). The complete mitogenome has a total of sixty-three unique genes, including thirty-nine protein-coding genes, twenty-one transfer RNAs (tRNAs) and three ribosomal RNAs (rRNAs). We examined codon use, repeat sequence, RNA editing in the mitogenome of P. sibiricum, and elucidated species classification based on phylogenetic trees of mitogenome of twenty-three species. Our results provide comprehensive information on the mitogenome of P. sibiricum and show for the first time the evolutionary relationship between the mitogenome of P. sibiricum and Chlorophytum comosum in the Asparagales family.
在本项目中，我们研究了百合科药用植物玉竹的完整线粒体基因组。该基因组由一个长度为691,910 bp、GC含量为46.33%的环状分子表示。线粒体基因组组成略微偏向A+T，AT占53.67%，AT偏度略为正值（0.092%）。完整的线粒体基因组共有63个独特基因，包括39个蛋白质编码基因、21个转运RNA（tRNA）和3个核糖体RNA（rRNA）。我们研究了玉竹线粒体基因组中的密码子使用、重复序列、RNA编辑，并基于23个物种的线粒体基因组系统发育树阐明了物种分类。我们的结果提供了关于玉竹线粒体基因组的全面信息，并首次展示了玉竹线粒体基因组与天门冬科吊兰线粒体基因组之间的进化关系。
