Abstract

Turnip (Brassica rapa. ssp. rapa) is considered worldwide to be one of the most important leaf and root vegetable crops in the Brassicaceae family. However, to date, few chloroplast (cp) genomic resources have been reported for this genus. Here, we determined the complete cp genome sequences of Brassica rapa ssp. rapa. A 153,621 bp quadripartite cycle without any gap was obtained with a large single-copy region (LSC) of 83,512 bp, a small single-copy region (SSC) of 17,683 bp, and two inverted repeat (IR), IRa and IRb of 26,213 bp. A total of 132 genes were identified, including 87 protein-coding genes (PCG), 37 transfer RNA (tRNA), and 8 ribosomal RNA (rRNA). The phylogenetic analysis of ten other crops selected showed that the turnip was most closely related to the Brassica rapa.

摘要

萝卜（芜菁。亚种白菜）在全球范围内认为是十字花科的最重要的叶和根蔬菜作物之一。但是，迄今为止，该属的叶绿体（cp）基因组资源很少。在这里，我们确定了甘蓝型油菜的完整cp基因组序列。拉帕。获得了一个153,621 bp的四分体循环，没有任何间隙，其中有83,512 bp的大单拷贝区域（LSC），17,683 bp的小单拷贝区域（SSC）和两个反向重复（IR），IRa和IRb为26,213 bp。共鉴定出132个基因，包括87个蛋白质编码基因（PCG），37个转移RNA（tRNA）和8个核糖体RNA（rRNA）。对其他十种作物进行的系统发育分析表明，芜菁与甘蓝型油菜关系最密切。
