Abstract

Leyss 1761 is a perennial herb with large yield and famous for its high nutritional value and long utilization season. The study of chloroplast (cp) genome provides an important basis for the study of chloroplast genetic engineering and system evolution. Its cp genome was 137,153 bp in length, containing a pair of inverted repeated (IR) regions (21,699 bp), separated by a large single copy region (LSC) of 81,137 bp, and a small single copy (SSC) region of 12,618 bp. Moreover, a total of 129 functional genes were annotated, including 83 mRNA, 38 tRNA genes, and 8 rRNA genes. The phylogenetic relationships of 15 species indicated that was closely related to . This study might contribute to provide a theoretical basis for species identification and biological research.

摘要

莱氏草1761是一种多年生草本植物,产量高,以其高营养价值和长利用季节而闻名。叶绿体(cp)基因组的研究为叶绿体基因工程和系统进化研究提供了重要依据。其cp基因组长度为137,153 bp,包含一对反向重复(IR)区域(21,699 bp),由一个81,137 bp的大单拷贝区域(LSC)和一个12,618 bp的小单拷贝(SSC)区域隔开。此外,总共注释了129个功能基因,包括83个mRNA、38个tRNA基因和8个rRNA基因。15个物种的系统发育关系表明,[此处原文缺失相关物种信息]与[此处原文缺失相关物种信息]密切相关。本研究可能有助于为物种鉴定和生物学研究提供理论基础。
