The complete chloroplast genome sequence of wild cucumber (Cucumis sativus var. Hardwickii)

The complete chloroplast genome sequence of wild cucumber (Cucumis sativus var. hardwickii) was generated by de novo assembly with low-coverage whole-genome sequence data. The 155 277 bp genome containing a pair of inverted repeats (IRs) of 25 198 bp separated by a large single-copy region of 86 618 bp and a small single-copy region of 18 263 bp. The chloroplast genome contains 130 known genes, including 89 protein-coding genes, eight rRNA genes (four kinds), and 37 tRNA genes (30 kinds). Eighteen genes are duplicated in the inverted repeat regions, 16 genes contain one intron, two genes, and one ycf contain two introns. Phylogenomic analysis showed that C. sativus var. Hardwickii is closely related to C. sativus and C. hystrix.
