The complete chloroplast genome of Guillardia theta strain CCMP2712.

The complete chloroplast sequence of Cryptophyceae algae Guillardia theta strain CCMP2712 was determined in this study. The genome consists of 138 455 bp containing a pair of rRNA-coding invert repeats of 4973 bp. The overall GC contents of the chloroplast genome were 32.9%. A total of 159 functional genes were annotated, which included 124 protein-coding genes, 30 tRNAs, 1tmRNA and 4 rRNA genes. Short intergenic regions, no introns and some overlapping genes make this cp genome compact. Phylogenetic analysis with the related algae cp genomes revealed that G. theta strain CCMP2712 a typical Cryptophyta algae and had a close genetic relationship with Rhodomonas salina (EF508371) and another previously reported G. theta (AF041468).
