Abstract
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).
