Characterization of the complete plastid genome of Porphyridium purpureum strain CCMP1328

In this study, the complete plastid genome of Porphyridium purpureum strain CCMP1328 was recovered through Illumina sequencing data. This complete plastid genome of P. purpureum was 220,483 bp in length and contained a pair of IR regions (4604 bp). The pt genome of P. purpureum encoded 234 genes including 199 protein-coding genes, 29 tRNA genes, one tmRNA, and six ribosomal RNA genes in IR regions. The overall GC content of P. purpureum cp genome is 30.4%. By phylogenetic analysis using 18S DNA fragments through NJ method, P. purpureum strain CCMP1328 was grouped in the P. purpureum cluster without further distinction. This complete plastid genomes can be subsequently used for evolution studies of red algae and provide valuable insight into dynamic evolution of group II introns.
