Characterization of the complete chloroplast genome of Sargassum fusiforme and its phylogenomic position within phaeophyceae

Abstract

Sargassum fusiforme is an important economic seaweed in East Asia. In this study, we characterized the complete chloroplast genome sequence of S. fusiforme using PacBio long-read sequencing technology. It had a circular mapping molecular with the length of 124,286 bp, with a large single-copy region (LSC, 73,437 bp) and a small single copy region (SSC, 40,131 bp) separated by a pair of inverted repeats (IRs, 5,359 bp). The cp genome contained 173 genes including 139 protein-coding, 6 rRNA, and 28 tRNA genes. The phylogenomic analysis indicated that S. fusiforme is closely related to S. thunbergii.
