The complete mitochondrial genome of Tanacetipathes thamnea Warner, 1981 (Antipatharia: Myriopathidae)

Abstract

Specimens of the black coral Tanacetipathes thamnea were collected from the Northwestern Gulf of Mexico. The complete mitochondrial genome of one of these specimens was obtained from genomic DNA by next-generation sequencing technology on the Illumina HiSeq 2500. Only three species of black corals have a completely sequenced mitochondrial genome. These were used to reconstruct the phylogeny for the order Antipatharia. The mitochondrial genome of T. thamnea is 17,712 base pairs and contains 13 protein-coding genes, 2 ribosomal RNAs, and 2 transfer RNAs in the following order: 16s RNA, COX3 , COX1 (with intron), ND4L , COX2 , ND4 , ND6 , ATP8 , ATP6 , and ND5 (with intron and copies of ND1 and ND3 ), tRNA-Trp , ND2 , 12s RNA , CYTB , tRNA-Met . The gene arrangement is the same as that for Myriopathes japonica with a nearly identical sequence (99.35% identical). These results show that the mitochondrial genome within the family Myriopathidae is highly conserved.

Phylogenetics and Mitogenome Organisation in Black Corals (Anthozoa: Hexacorallia: Antipatharia): An Order-Wide Survey Inferred From Complete Mitochondrial Genomes

“…Hexacoral mitogenomes share some unique properties amongst metazoans. Complete mitogenomes have been sequenced for species from each of the five hexacoral orders: Actiniaria (Foox et al, 2015;Zhang et al, 2017), Antipatharia (Brugler and France, 2007;Kayal et al, 2013;Figueroa et al, 2019), Corallimorpharia (Lin et al, 2014), Scleractinia (Medina et al, 2006), and Zoantharia (Sinniger et al, 2007;Chi and Johansen, 2017). Consistent is a reduced set of the 22 tRNAs necessary for mitochondrial translation, with only tRNA −met (Methionine) and tRNA −trp (Tryptophan) being present.…”

“…The gene order was described as most similar to the sea anemone Metridium senile, with the exception of a transposition of three continuous genes COX2-ND4-ND6 and lack of a COX1 intron. However, the subsequent fully sequenced antipatharian mitogenomes, Stichopathes luetkeni (Kayal et al, 2013), Myriopathes japonica (GenBank NC_027667.1), Tanacetipathes thamnea (Figueroa et al, 2019) and the partially sequenced Leiopathes glaberrima (Sinniger and Pawloski, 2009) had a COX1 intron containing a HEG gene. With the exception of the COX1 intron, gene content was the same as in C. formosa.…”
