In this study, we determined the complete chloroplast genomes from two crucifer species of the Eutrema genus. The sizes of the two cp genomes were 153 948 bp (E. yunnanense) and 153 876 bp (E. heterophyllum). Both genomes have the typical quadripartite structure consisting of a large single copy region, a small single copy region and two inverted repeats. Gene contents and their relative positions of the 132 individual genes (87 protein-coding genes, eight rRNA, and 37 tRNA genes) of either genome were identical to each other. Phylogenetic analysis supports the idea that the currently recognized Eutrema genus is monophyletic and that E. salsugineum and Schrenkiella parvula evolved salt tolerance independently.
在本研究中，我们测定了盐芥属两种十字花科植物的完整叶绿体基因组。这两个叶绿体基因组的大小分别为153948 bp（云南盐芥）和153876 bp（异叶盐芥）。两个基因组均具有典型的四分体结构，由一个大单拷贝区域、一个小单拷贝区域和两个反向重复序列组成。两个基因组的132个独立基因（87个蛋白质编码基因、8个rRNA基因和37个tRNA基因）的基因内容及其相对位置彼此相同。系统发育分析支持以下观点：目前公认的盐芥属是单系的，并且盐地碱蓬和小盐芥独立进化出了耐盐性。
