The whole nucleotide sequence of the chloroplast genome from Capsella rubella is determined in this study using short Illumina sequence data from public database. The circular double-stranded DNA, which consists of 154,601 base pairs (bp) in size, contains a pair of inverted repeats (IRa and IRb) of 26,462 bp each, which are separated by a small and large single-copies (SSC and LSC) of 17,855 and 83,822 bp, respectively. The overall GC content of the chloroplast genome is 36.54% and the GC contents of LSC, IRs and SSC are 34.33%, 42.38% and 29.61% separately. One hundred and twelve unique genes were annotated, including 78 protein-coding genes, 30 tRNA genes and 4 rRNA genes. Among these, 16 are duplicated in the inverted repeat regions, 15 genes contained 1 intron, and 3 genes (rps12, clpP and ycf3) comprised of 2 introns. Two protein genes (rps19 and ycf1) span in the boundaries of LSC-IR and IR-SSC to produce two partial pseudogenes.
本研究利用来自公共数据库的短读长Illumina序列数据，测定了风花菜叶绿体基因组的全核苷酸序列。该环状双链DNA大小为154,601碱基对（bp），包含一对大小均为26,462 bp的反向重复序列（IRa和IRb），它们被大小分别为17,855 bp和83,822 bp的一个小单拷贝区（SSC）和一个大单拷贝区（LSC）隔开。叶绿体基因组的总体GC含量为36.54%，LSC、IR和SSC的GC含量分别为34.33%、42.38%和29.61%。共注释了112个独特基因，包括78个蛋白质编码基因、30个tRNA基因和4个rRNA基因。其中，16个基因在反向重复区域中重复，15个基因含有1个内含子，3个基因（rps12、clpP和ycf3）含有2个内含子。两个蛋白质基因（rps19和ycf1）跨越LSC-IR和IR-SSC边界，产生两个部分假基因。
