摘要: The genus Cucumis contains 52 species, including two economically significant crops, cucumber, and melon, as well as some important landraces. Cucumis melo L. 'Shengkaihua' is a widely cultivated landraces in China. It has high sugar content, early maturity, and strong genetic growth potential. Cucumis melo L. 'Shengkaihua' provides a valuable gene pool for crop improvement of Cucumis crops. In this study, the complete chloroplast (cp) genome sequence of C. melo L. 'Shengkaihua' was determined using next-generation sequencing. The entire cp genome was determined to be 156,017 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 86,335 and 18,088 bp, respectively, which were separated by a pair of 25,797 bp inverted repeat (IR) regions. The genome contained 133 genes, including 88 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the genome is 36.9%. A phylogenetic tree reconstructed by 24 chloroplast genomes reveals that C. melo L. 'Shengkaihua' is most related to Cucumis melo var. inodorus.
