is a kind of Chinese traditional herbs with economic and ornament value, widely distributed in China. Despite its significance, there have been limited comprehensive investigations on the genome of , particularly regarding mitochondrial genomes. To investigate the conversion between mitochondrial genome and chloroplast genome, a complete and circular mitochondrial genome was assembled using Oxford Nanopore Technologies (ONT) long reads. The mitochondrial genome of had a length of 228,315 base pairs (bp) with 45.06% GC content. The mitochondrial genome encodes 56 genes, including 34 protein-coding genes, 19 tRNA genes and 3 rRNA genes. Moreover, we discovered that 9 homologous large fragments between chloroplast genome and mitochondrial genome based on sequence similarity. This is the first report for mitochondrial genome, which could provide an insight for communication between plastid genome, and also give a reference genome for medicinal plants within the Angelica family.
是一种具有经济和观赏价值的中国传统草药,在中国广泛分布。尽管其具有重要意义,但对其基因组,特别是线粒体基因组的全面研究仍然有限。为了研究线粒体基因组与叶绿体基因组之间的转化,使用牛津纳米孔技术(ONT)长读段组装了一个完整的环状线粒体基因组。该植物的线粒体基因组长度为228,315碱基对(bp),GC含量为45.06%。线粒体基因组编码56个基因,包括34个蛋白质编码基因、19个tRNA基因和3个rRNA基因。此外,基于序列相似性,我们发现叶绿体基因组和线粒体基因组之间有9个同源大片段。这是该植物线粒体基因组的首次报道,可为质体基因组之间的交流提供见解,也为当归科药用植物提供参考基因组。
