In this work, the complete mitogenome of cultivar 'Dongfang No.3' is reported. This mitogenome has a circular mapping organization with the length of 37,657 bp and contains 66 genes, including 35 protein-coding genes, three rRNAs, 25 tRNAs, and three open reading frames (s). The overall AT content is 64.73%, showing a higher AT content. The gene content and gene sequence are consistent with those reported varieties and cultivars of . Chinese main cultivars are analyzed by phylogenetic analysis. It indicates that 'Dongfang No.3' has a close relationship with , which strongly supports its genetic origin. The complete mitogenome analysis in this work would help in understanding the genetic background of Chinese cultivars.
在本研究中，报道了栽培品种‘东方3号’的完整线粒体基因组。该线粒体基因组具有环状图谱结构，长度为37,657 bp，包含66个基因，其中包括35个蛋白质编码基因、3个rRNA、25个tRNA和3个开放阅读框。总体AT含量为64.73%，显示出较高的AT含量。基因含量和基因序列与已报道的品种和栽培品种一致。通过系统发育分析对中国主要栽培品种进行了分析。结果表明，‘东方3号’与[具体品种未提及]关系密切，有力地支持了其遗传起源。本研究中的完整线粒体基因组分析将有助于了解中国[具体作物未提及]栽培品种的遗传背景。
