Characterization of the chloroplast genome of the marine microalga Tetraselmis marina (Cienkowski) R.E.Norris, Hori & Chihara 1980

Abstract

Tetraselmis marina (Cienkowski) R.E.Norris, Hori & Chihara 1980, a costal green microalga, is considered as a promising animal feed in aquaculture due to the high content of fatty acids and carotenoid. Furthermore, T. marina plays important roles in bioremediation. In this study, we assembled the complete chloroplast genome of T. marina. Results showed that the full length of the complete chloroplast genome was 96,151 bp, containing a large single-copy region of 62,574 bp, a small single-copy region of 1261 bp, and a pair of inverted repeat regions of 16,158 bp. The GC content of the genome was 36.6%. A total of 125 genes were annotated, including 81 protein coding genes, 38 tRNA genes, and six rRNA genes. Phylogenetic analysis based on 22 chloroplast genomes suggested that T. marina was closely related to Tetraselmis sp. CCMP 881.
