Complete chloroplast genome of green alga (Forsskål) J.Agardh, 1837.

The complete chloroplast genome of from South China Sea has been assembled and characterized for the first time. The circular chloroplast genome was 177,848 bp in length, with a GC content of 33.80%. It contained 117 genes, which included 78 protein-coding genes, 37 tRNA genes, and 2 ribosomal RNA genes. Like other species in , the chloroplast genome of did not demonstrate a typical quadripartite structure. A total of 35 microsatellites (SSRs) were identified in the genome using MISA. Phylogenetic analysis showed that was closer to , which further clarified the phylogenetic relationships of species in .
