Abstract
The complete nucleotide sequence of the wild cucumber (C. hystrix Chakr.) chloroplast genome has been determined in this study. The genome was composed of 155,031 bp containing a pair of inverted repeats (IRs) of 25,150 bp, which was separated by a large single-copy region of 86,564 bp and a small single-copy region of 18,166 bp. The chloroplast genome contained 130 known genes, including 89 protein-coding genes, 8 ribosomal RNA genes (4 rRNA species) and 37 tRNA genes (30 tRNA species), with 18 of them located in the IR region. In these genes, 16 contained 1 intron, and 2 genes and one ycf contained 2 introns.
