Abstract

Vicia costata Ledeb. is a fine leguminous pasture which has advantages of drought resistance and barren tolerance. In this study, the complete chloroplast (cp) genome of V. costata was assembled and annotated. The total genome size of V. costata was 134,184 bp in length with IR loss. The cp genome encoded a set of 112 genes, containing 74 protein-coding genes, 34 tRNA genes, and 4 rRNA genes. The overall GC content was 34.82%. Phylogenetic analysis showed that V. costata got together with the same genus species V. ramuliflora, V. bungei, V. faba, V. sativa and V. sepium with high support value, and V. costata had a close relationship with V. ramuliflora. The whole cp genome of V. costata will be a useful resource for future studies on phylogeny and conservation in Vicia.

摘要

蚕豆肋脉草木樨。是一种优良的豆科牧草，具有抗旱和耐贫瘠的优点。在这项研究中，V的完整叶绿体（cp）基因组。costata已组装并添加注释。总基因组大小五肋脉是在IR损失长度134184基点。cp基因组编码了112个基因，其中包含74个蛋白质编码基因，34个tRNA基因和4个rRNA基因。总GC含量为34.82％。系统发育分析表明，五肋脉与同属种在一起了五ramuliflora，五，牡丹，蚕豆，五，水稻和五柳高支持度，以及五肋脉有一个密切的关系V. ramuliflora。全基因组CP五肋脉将是未来在系统发育和保护研究的有用资源蚕豆。
