- Abstract
- This paper reports on the basic characteristics of the mitochondrial genome of the intertidal copepod Tgriopits sp. from Korea, including its structural organization, base composition of rRNAs and protein-encoding genes, and the secondary structure of tRNAs. We amplified the complete mitochondrial DNA of the intertidal copepod Tigriopits sp. from Korea (sampling site Busan) by long-polymerase chain reaction (long-PCR) with conserved primers and sequenced this mitogenome by primer walking using flanking sequences as sequencing primers. The primer informations were obtained as expressed sequence tags (ESTs) from Tigriopus sp. The resultant Tigriopus sp. mitochondrial DNA sequence was 14,301 bp with a conserved structural organization, compared to that of T japonicus from Japan with significant differences in several protein-coding regions including rRNAs, although the genomic organization of the mitochondrial genome was identical. In order to investigate biogeographic differences within the genus Tigriopus, we analyzed the COI gene by sequencing. This way, we compared several Tigriopus species from Korea, Japan, Hong Kong and Taiwan as well as other related species such as T californicus, T brevicornis and T fulvus. The results further support the notion that the copepods display significantly different genomes within the same genus. These findings provide valuable genomic information for further studies on the population genetics and speciation processes within the genus Tigriopus.
