The complete chloroplast genome sequence of male individual of Korean endemic willow, Salix koriyanagi Kimura ex Goerz (Salicaceae)

Abstract

As a Korean endemic plant, Salix koriyanagi Kimura ex Goerz belongs to the genus Salix L. which is the largest genus of Salicaceae. In this study, we presented a complete chloroplast genome from male individual of S. koriyanagi which is 155,548 bp and has four subregions: 84,415 bp of large single copy (LSC) and 16,125 bp of small single copy (SSC) regions are separated by 27,459 bp of inverted repeat (IR) regions including 131 genes (85 protein-coding gene, 8 rRNAs, and 38 tRNAs). The overall GC content of the chloroplast genome is 36.7% and those in the LSC, SSC, and IR regions are 34.4%, 31.0%, and 41.9%, respectively. SSC is inverted in comparison to that of female individual of S. koriyanagi. Phylogenetic trees show phylogenetic relationship of Salix and Populus genera.
