The complete chloroplast genome sequence of Oxalis corniculata (L.)

Oxalis corniculata L. is a perennial herb with a world-wide distribution. In this study, we sequenced the complete chloroplast genome of O. corniculata, which exhibited a circular genome of 155,182 bp in length with 37.5% GC content. The chloroplast genome contained a canonical quadripartite structure with a large single copy (LSC) region of 83,936 bp, a small single copy (SSC) region of 17,048 bp and a pair of 25,581 bp inverted repeats (IRs). A total of 108 unique genes, including 76 protein-coding genes (PCGs), 28 tRNA genes and four rRNA genes were found in this chloroplast genome. The phylogenetic tree was constructed based on O. corniculata and other 11 chloroplast genome sequences, which showed that O. corniculata was closely grouped with of O. corymbosa and O. drummondii.

Automated summary

In this study, the complete chloroplast genome of Oxalis corniculata was sequenced, revealing its circular genome structure with a variety of genes, and a close phylogenetic relationship with two other plant species.
