Complete chloroplast genome of red seaweed Halymenia maculata (J. Agardh, 1885).

In this study, we first assembled and characterized the complete chloroplast genome of red seaweed Halymenia maculata. It is 190,431 bp in length, with an AT content of 70.56%. In total, 122 genes were identified, and they consisted of 87 protein-coding genes, 33 tRNA genes, and two rRNA genes. The chloroplast genome of H. maculata did not show an obvious quadripartite structure. A total of five microsatellites (SSRs) were identified in the genome using MISA. Phylogenetic analysis revealed that H. maculata was first clustered with Grateloupia filicina and Grateloupia taiwanensis in a monophyletic clade that provides useful data for the phylogeny and taxonomy of Rhodymeniophycidae.
