Abstract

Carmine radish, which contained a high natural red pigment (red radish pigment), was peculiar produced in Fuling, Chongqing City. Here, the complete nucleotide sequences of the mitochondrial (mt) genome of carmine radish () have been determined with a circular sequence with the lengths of 258,965 bp, comprised of 40 protein-coding genes, 23 tRNA genes, and three ribosomal RNA genes. To demonstrate the evolution of organelles genomes in plants, other plant mitochondrial genomes' evolution were also selected for analyze. The results showed that carmine radish is related to MS_Gensuke and Black radish , as well as related to Brassica nigra and Brassica carinata, comparing with other Brassicaceae species. This study will provide important genetic tools for other Brassicaceae species research and improve yields of economically important plants.

摘要

胭脂萝卜富含天然红色素(红萝卜色素),是重庆市涪陵区特有的产物。在此,已确定了胭脂萝卜()线粒体(mt)基因组的完整核苷酸序列,其为一个长度为258,965 bp的环状序列,由40个蛋白质编码基因、23个tRNA基因和3个核糖体RNA基因组成。为了阐明植物细胞器基因组的进化,还选择了其他植物线粒体基因组进行分析。结果表明,与其他十字花科物种相比,胭脂萝卜与MS_Gensuke和黑萝卜相关,也与黑芥和埃塞俄比亚芥相关。本研究将为其他十字花科物种的研究提供重要的遗传工具,并提高经济作物的产量。
