Characterization of the complete chloroplast genome of Hordeum vulgare L. var. trifurcatum with phylogenetic analysis

Abstract

In the present study, the complete chloroplast genome of Hordeum vulgare L. var. trifurcatum was sequenced, assembled and compared with closely related species. The chloroplast genome of Hordeum vulgare L. var. trifurcatum was composed of 84 protein-coding genes (PCG), 8 ribosomal RNA (rRNA) genes, and 38 transfer RNA (tRNA) genes. The Hordeum vulgare L. var. trifurcatum chloroplast genome is 136,485 bp in size, with the GC content of 38.32%. Phylogenetic analysis based on the combined chloroplast gene dataset indicated that the Hordeum vulgare L. var. trifurcatum exhibited a close relationship with Hordeum vulgare subsp. spontaneum and Hordeum vulgare subsp. vulgare.
