Complete mitochondrial genome sequence of Aequorea coerulescens.


ABSTRACT: The complete mitochondrial genome sequences of hydromedusa Aequorea coerulescens, a dominant giant jellyfish distributing in the Yellow Sea and northern East China Sea, China, is first reported in this research. Its mitochondrial DNA has 14,804?bp in length with a linear structure, containing 13 protein-coding genes (PCGs), 2rRNA (s-rRNA and l-rRNA), and 2tRNA (trnaW-TGA and tranM-AGT). The A?+?T content of the whole base composition of the genome is 72.8% (A: 30.15%; C: 12.33%; G: 14.87%; T: 42.64%). ATG, ATA, and ATT are start codons in five (ATP8, ATP6, COX3, NAD6, NAD4l), four (NAD2, NAD5, NAD1, COX1) and two PCGs (NAD3, NAD4), respectively. COB and COX2 began with GTG and CAA as start codon, respectively. TAA and ATA were the stop codon of ATP6 and NAD5 as well as NAD2 and NAD4, respectively. However, other PCGs were terminated with different stop codons. The NJ phylogenetic tree among the related 15 jellyfish species showed that A. coerulescens is close to Hydra spp.

The complete mitochondrial genome sequences of hydromedusa <i>Aequorea coerulescens</i>, a dominant giant jellyfish distributing in the Yellow Sea and northern East China Sea, China, is first reported in this research. Its mitochondrial DNA has 14,804 bp in length with a linear structure, containing 13 protein-coding genes (PCGs), 2rRNA (s-rRNA and l-rRNA), and 2tRNA (trnaW-TGA and tranM-AGT).
