Comparative Analyses of Chloroplast Genomes of Cucurbitaceae Species: Lights into Selective Pressures and Phylogenetic Relationships.

ABSTRACT: Cucurbitaceae is the fourth most important economic plant family with creeping herbaceous species mainly distributed in tropical and subtropical regions. Here, we described and compared the complete chloroplast genome sequences of ten representative species from Cucurbitaceae. The lengths of the ten complete chloroplast genomes ranged from 155,293 bp (C. sativus) to 158,844 bp (M. charantia), and they shared the most common genomic features. 618 repeats of three categories and 813 microsatellites were found. Sequence divergence analysis showed that the coding and IR regions were highly conserved. Three protein-coding genes (accD, clpP, and matK) were under selection and their coding proteins often have functions in chloroplast protein synthesis, gene tran
