Characterization of the Complete Plastid Genome of Campylaephora boydenii (Ceramiaceae, Florideophyceae)

Abstract

The complete plastid genome of Campylaephora boydenii was sequenced and characterized. The new circular genome (OQ731916) is 171,790 bp in length with 27.7% GC content. The genome included 233 genes; 200 protein-coding sequences (CDS), 28 transfer RNA (tRNA), three ribosomal RNA (rRNA), one intron, and one transfer-messenger RNA (tmRNA) gene. The gene content and synteny of C. boydenii were highly congruent with those of other ceramiacean species, such as C. sungminbooi and Ceramothamnion japonicum. In 200 CDSs, four CDS showed significant differences (± 5%) in length, i.e., cpcG, petP, rpl33, and thiS. The trnM was a unique tRNA included group II intron with intronic-ORF. Additional complete plastid genomes of ceramiacean algae will provide significant information for the ecology, genetic diversity and phylogeny of ceramialean red algae.
