The complete chloroplast genome of Hordeum marinum ssp. marinum

ssp. (Huds.) R. J. Soreng (2003) is a halophyte wild relative of barley and wheat, which exhibits remarkable salt tolerance characteristics. In this study, we presented the first characterization of the complete chloroplast genome of ssp. . Our findings reveal that the chloroplast genome of ssp. consists of a small single-copy region (SSC: 12,715 bp), a large single-copy region (LSC: 81,130 bp), and a pair of inverted repeat regions (IRs: 21,517 bp), amounting to a total length of 136,989 bp. The chloroplast genome encodes 139 genes, including 91 protein-coding genes, 38 tRNA genes, and ten rRNA genes. By utilizing phylogenetic analysis, we determine the evolutionary position of in Triticeae. Our study provides valuable insights into the chloroplast genome of ssp. , which may have important implications for the improvement of cereal crops.
