Wild oat, L. is a stout broad-leaved annual grass resembling cultivated oats in general appearance. In this study, we sequenced the complete chloroplast (cp) genome sequence of for the first time to investigate their phylogenetic relationship in the family Poaceae. The complete cp genome sequence is 135,887 bp in length with 38.5% overall GC content and exhibits a typical quadripartite structure comprising one pair of inverted repeats (21,603 bp) separated by a small single-copy region (12,575 bp) and a large single-copy region (80,106). The cp genome encodes 111 unique genes, 76 of which are protein-coding genes, four rRNA genes, 30 tRNA genes, and 18 duplicated genes in the inverted repeat region. The phylogenetic analysis indicated closely clustered with the cultivated oat, L.
野燕麦，L. 是一种粗壮的阔叶一年生草本植物，总体外观与栽培燕麦相似。在本研究中，我们首次对其叶绿体（cp）基因组序列进行了测序，以研究它们在禾本科中的系统发育关系。完整的cp基因组序列长度为135,887 bp，总体GC含量为38.5%，呈现出典型的四分体结构，由一对反向重复序列（21,603 bp）组成，中间被一个小单拷贝区域（12,575 bp）和一个大单拷贝区域（80,106）隔开。cp基因组编码111个独特基因，其中76个是蛋白质编码基因，4个rRNA基因，30个tRNA基因，以及反向重复区域中的18个重复基因。系统发育分析表明，与栽培燕麦L. 紧密聚类。
