Sechium edule (Jacq.) Swartz is an important vegetable with both food and medicinal values. The complete chloroplast genome sequence of S. edule has been reported in this study. The total genome si...

Cucumis melo L. is one of the most important fruit-type vegetables in the world. This genome is divided into a main loop and two small loops. The length of the main loop is 2,709,526 bp, and the two small loops are 149,555 bp and 47,592 bp long, respectively. There are 88 coding genes in the melon mitochondrial genome, including 40 protein-coding genes (which accounted for about 1.23% of the whole genome), 8 rRNAs, and 40 tRNAs. The total length of rRNAs and tRNAs spans 0.31% of the total genome sequence. Among the 88 mitochondrial coding genes, only 5 tRNAs were located into the second largest circular DNA molecule. The complete mitogenome sequence provided herein would help understand C. melo evolution.

Citrullus colocynthis L. is one of the worldwide famous traditionally medicinal plants and widely applied in watermelon breeding for its multiple resistances. The complete nucleotide sequence of desert watermelon (Citrullus colocythis L.) chloroplast genome has been determined in this study. The genome was composed of 157,147 bp containing a pair of inverted repeats (IRs) of 26,149 bp, which was separated by a large single-copy region of 86,851 bp and a small single-copy region of 17,998 bp. A total of 123 genes were predicted including 86 protein-coding genes, eight rRNA genes and 29 tRNA genes. Phylogenetic analysis revealed that C. colocynthis were closely related to other two species in the genus Citrullus. The complete chloroplast genome of C. colocynthis would provide some significant information for Cucurbitaceae evolutionary and genomic studies.
