Complete chloroplast genome sequence and phylogenetic analysis of Gloiopeltis furcata (Gigartinales, Florideophyceae)

Gloiopeltis furcata is an annual red alga of Endocladiaceae, Florideophyceae, showing high economic and medical values. The chloroplast genome is instrumental for evolutionary studies, yet that of G. furcata remains unreported. Here, the chloroplast genome of G. furcata was assembled and analyzed. The genome size is 177,606 bp, which contains 184 genes (152 protein-coding genes, 29 tRNAs, and 3 rRNAs). Four simple sequence repeat (SSR) types were detected. The AGA-encoded arginine had the highest relative synonymous codon usage (RSCU) value, while CGG-encoded arginine had the lowest. Phylogenetic analysis indicated that G. furcata is a sister to Chondrus crispus.
