Complete mitochondrial DNA sequence of the Australian freshwater crayfish, Cherax destructor (Crustacea: Decapoda: Parastacidae): a novel gene order revealed

Genetic characterization of the mitochondrial DNA from Lepeophtheirus salmonis (Crustacea; Copepoda). A new gene organization revealed

“…However, several unusual start codons have been proposed for COI in different arthropods (ATTA in D. pulex, ATCA in P. longicarpus, ACG in C. destructor and S. mantis, GTT in N. cristatus and ATAA in D. yakuba) (Clary and Wolstenholme, 1985;Crease, 1999;Hickerson and Cunningham, 2000;Machida et al, 2004;Miller et al, 2004;NC _ 006081). In L. salmonis the five start codons ATG, ATT, ATA, ATC and GTT are being used, while TAA and TAG are the only stop codons (Table 2).…”

“…So far, the complete mitochondrial genome has been sequenced from 14 crustacean species; four branchiopods [Daphnia pulex (Crease, 1999), Artemia franciscana (Valverde et al, 1994), Triops cancriformis (Umetsu et al, 2002) and Triops longicaudatus (NC _ 006079)], six decapods [Pagurus longicarpus (Hickerson and Cunningham, 2000), Penaeus monodon (Wilson et al, 2000), Panulirus japonicus (Yamauchi et al, 2002), Portunus trituberculatus (Yamauchi et al, 2003), Cherax destructor (Miller et al, 2004) and Callinectes sapidus (Place et al, unpublished)], one stomatopod [Squilla mantis (NC _ 006081)], one cirriped [Tetraclita japonica (Begum et al, unpublished)], one ostracod [Vargula hilgendorfii (Ogoh and Ohmiya, 2004)] and one copepod [Tigriopus japonicus (Machida et al, 2002)]. In addition, the two copepods Eucalanus bungii and Neocalanus cristatus have been partly characterized (Machida et al, 2004).…”

A polymerase chain reaction‐restriction fragment length polymorphism method based on the analysis of a 16S rRNA/tRNAVal mitochondrial region for species identification of commercial penaeid shrimps (Crustacea: Decapoda: Penaeoidea) of food interest

“…However, although the complete mtDNA sequences have been determined for approximately 370 species, the majority (approximately 75%) of such species correspond to vertebrates. Indeed, from less than 50 complete mtDNA sequences of the phylum Arthropoda currently available at GenBank, only a few correspond to the subphylum Crustacea [24], a situation that highlights the paucity of information that could be useful for authentication purposes in this group of aquatic food products. Among the mtDNA targets, the 16S rRNA gene and, to a lesser degree, the cytochrome oxidase I (COI) gene have been reported to serve as good intraspecific markers in some crustacean species [25][26][27][28][29].…”

Mitochondrial Genome Haplotype Hypervariation Within the Isopod Parasitic Nematode Thaumamermis cosgrovei

“…However, a growing literature from physical evidence (Lunt and Hyman 1997;Kajander et al 2000;Ladoukakis and Zouros 2001a;Hoarau et al 2002;Passamonti et al 2003;D'Aurelio et al 2004;Kraytsberg et al 2004;Guo et al 2006), biochemical studies (Thyagarajan et al 1996), and quantitative genetics analysis (Awadalla et al 1999;Ladoukakis and Zouros 2001b;Piganeau et al 2004;Gantenbein et al 2005;Tsaousis et al 2005) from metazoa spanning large taxonomic distances suggests that intramolecular and/or intermolecular recombination can operate on animal mtDNAs. Recombination is now proposed to be a major underlying mechanism that generates highly rearranged mitochondrial genomes in numerous animal lineages (Dowton et al 2003;Miller et al 2004;Mundy and Helbig 2004;Endo et al 2005;Nohara et al 2005;Shao et al 2005). Size polymorphism, heteroplasmy, and mitochondrial genome rearrangement is a common feature among available Enoplean nematode mtDNA complete sequences, including the family Mermithidae, and stands in contrast to the conserved economization and stable gene orders that typify the Chromadorean nematodes (He et al 2005).…”
