The complete chloroplast genome of Sargassum hemiphyllum var. Chinense (Sargassaceae, Phaeophyceae) and its phylogenetic analysis

Abstract

Sargassum hemiphyllum (Turner) C. Agardh is an important brown macroalga. In this study, we presented the complete chloroplast genome of its variety S. hemiphyllum var. chinense using genome skimming approach. Circular mapping revealed its sequence length was 124,319 bp, with a large single-copy region (LSC, 73,505 bp) and a small single copy region (SSC, 39,922 bp) separated by a pair of inverted repeats (IRs, 5446 bp). Its chloroplast genome contained 173 genes, including 139 protein-coding, 6 rRNA, and 28 tRNA genes. The phylogenetic analysis indicated that S. hemiphyllum var. chinense was closely related with S. confusum.
