'Deqin' is an excellent alfalfa landrace with strong drought and heat resistant which can grow and propagate very well in Deqin, a xerothermic valley of Jinsha River, China. In this study, the complete chloroplast genome of 'Deqin' was assembled. The complete chloroplast genome of 'Deqin' represents a typical circular with 125,470 bp in length, containing one inverted repeat (IR) region. Gene prediction revealed 110 genes encoding 76 proteins, 30 transfer RNAs, and four ribosome RNAs. Three genes (, and ) are absent. The overall GC content is 33.9%. The phylogenetic analysis revealed that 'Deqin' belonged to the IR lacking clade, and was closely related to with a 100% bootstrap support.
“德钦”是一种优良的紫花苜蓿地方品种，具有很强的抗旱和耐热性，在中国金沙江干热河谷的德钦地区能够很好地生长和繁殖。在本研究中，组装了“德钦”的完整叶绿体基因组。“德钦”的完整叶绿体基因组呈典型的环状，长度为125470 bp，包含一个反向重复（IR）区域。基因预测显示有110个基因，编码76种蛋白质、30个转运RNA和4个核糖体RNA。三个基因（、和）缺失。总体GC含量为33.9%。系统发育分析表明，“德钦”属于缺乏IR的分支，与具有100%的自展支持率，关系密切。 （注：原文中部分基因名称缺失，翻译时保留原文格式）
