The complete chloroplast genome sequence with a novel 24-bp deletion of a Korean solid green-type cucumber variety (Cucumis sativus var. sativus)

Abstract

Cucumber (Cucumis sativus var. sativus) is one of the economically important vegetable crops. In this study, we characterized the complete chloroplast genome sequence of inbred line ID YHB bred from Korean solid green-type cucumber variety, through de novo assembly using next-generation sequencing. The chloroplast genome is 155,501 bp long and has typical quadripartite structures and gene contents as found in reported cucumber chloroplast genomes. Interestingly, sequence comparison revealed a novel 24-bp deletion present only in the chloroplast genome of the inbred line. Phylogenetic analysis confirmed that the inbred line was closely grouped with cucumber cultivars.
