The complete chloroplast genome of () and its phylogenetic implication.

The genus contains 52 species, including two economically significant crops, cucumber and melon, as well as other important species. is a wild relative of , native to Africa. is rich in vitamins and minerals in gherkin fruits and carries broad-spectrum resistance to multiplex biotic and abiotic stress, such as powdery mildew, fusarium wilt, and meloidogyn incognita. provides a valuable gene pool for crop improvement of crops. In this study, the complete chloroplast (cp) genome sequence of was determined using next-generation sequencing. The entire cp genome was determined to be 156,577 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 85,971 and 18,100 bp, respectively, which were separated by a pair of 26,253 bp inverted repeat (IR) regions. The genome contained 134 genes, including 88 protein-coding genes, 37 tRNA genes, 8 rRNA genes and 1 pseudogene infA. The overall GC content of the genome is 37.0%. A phylogenetic tree reconstructed by 48 chloroplast genomes reveals that is a separate branch in .
