Complete mitochondrial genome of Stichaeus grigorjewi Herzenstein, 1890 (Zoarcales: Stichaeidae)

Abstract

The complete mitochondrial genome of Stichaeus grigorjewi (Zoarcales: Stichaeidae) was sequenced for the first time based on the 27 pairs of newly designed primers using Sanger dideoxy sequencing method. Genome structure is consistent with standard scheme known for the vertebrates including 13 gene fragments, two rRNAs, 22 tRNAs, and control region. Moreover, it has additional tRNAs with atypical codons. These features were previously found in Xiphister atropurpureus, which shows the closest position to S. grigorjewi as seen from the phylogram built on the sequences of complete mitochondrial genome.

The complete mitochondrial genome of Mactra chinensis (Bivalvia: Macridae)

“…All 12 PCGs started with the ATG initiation codon. A few atypical starts and stop codons were also found as well as in many other fish and shellfish taxa (Kartavtsev et al 2007;Shen et al 2014;Li et al 2014;Turanov et al 2019;Zheng et al 2019).…”

Complete mitochondrial genome of ocellated blenny, Opisthocentrus ocellatus (Tilesius, 1811) (Zoarcales: Opisthocentidae)

“…Incomplete stop codons were revealed in ND2, ND3, ND4, CONTACT Olesia A. Rutenko orutenko@gmail.com Chair of Biodiversity and Marine Bioresources, Far Eastern Federal University, 8 Sukhanova St., 690090 Vladivostok, Russia COII, ATPase 6, and Cyt-b genes. The atypical stop codons were also found in many other zoacids fishes, such as Stichaeus grigorjewi (Turanov et al 2019), Lycodes brevipes (Li et al 2019), Lycodes ygreknotatus (Zheng et al 2019), X. Atropurpureus (Group et al 2017), and in other taxa (Kartavtsev et al 2007;Satoh et al 2016).…”
