“…Several studies of control region in fishes have identified tandemly repeated sequences that vary in copy number among haplotypes (VNTRs; e.g. Chen et al, 1998;Gleeson et al, 1999). In the current study no such VNTRs were detected within species, although there was some evidence of minor length variation among species.…”

Mitochondrial control region sequence variation was examined in the Galaxias vulgaris complex, a group of freshwater-limited galaxiid fishes endemic to South Island, New Zealand. Phylogenetic analyses were used to test the monophyly of seven non-migratory (G. vulgaris complex) and one migratory (G. brevipinnis) species. Newly-described taxa, some diagnosed on the basis of subtle differences in morphology, are associated with strongly monophyletic mtDNA lineages. Although the current taxonomy is supported generally, sequence data suggest that Southland G. anomalus should be attributed to G. gollumoides, whereas Southland and Stewart Island G. depressiceps represent a new southern lineage. Molecular clock calibrations suggest that migratory and non-migratory forms, separated by a maximum of 6·4% sequence divergence, diverged no earlier than the mid-late Pliocene. Biogeographical implications of high diversity (eight lineages) in the south (Otago-Southland) and low diversity (one lineage) in central South Island (Canterbury) are discussed. The unresolved relationships among species may reflect a rapid evolutionary radiation, essentially a star phylogeny. 2001 The Fisheries Society of the British Isles

“…Interspecific variation between 11·3 and 11·7%, over the entire control region, and 22-34%, at the 5 end, has been reported in two freshwater gobiids (Chen et al, 1998). However, this result, sheds little light on the status of M. cephalus.…”

The striped mullet Mugil cephalus L. is a circumtropical species whose extreme conservative morphology stands in contrast with the degree of genetic differentiation at a global scale. One hundred and fourteen mitochondrial control region DNA sequences were analysed from four localities in the Gulf of Mexico (Texas, Louisiana, Mississippi, Florida), one on the U.S.A. east coast (N. Carolina), and one in Hawaii, giving very high levels of molecular diversity (h=1·0 every haplotype was unique in all samples, =1·1-2·0% in Gulf-Atlantic and =3·1% in Hawaii). With no genetic evidence of dramatic population expansions, mismatch distributions were still very different in each ocean. Stable population levels in Hawaii have fostered the generation and persistence of very high molecular diversity, but Gulf-Atlantic samples suggest a shorter span of population stability. Ninety-five per cent of the molecular variance was allocated between ocean basins and virtually none among Gulf-Atlantic samples. A neighbourjoining reconstruction revealed Atlantic-and Pacific-specific lineages separated by more than 24% uncorrected sequence divergence (d=0·49 Tamura-Nei Gamma-corrected). The lack of phylogeographic structure among Gulf-Atlantic samples corroborated the AMOVA results and supported the existence of a single population with high levels of gene flow along the Gulf of Mexico and north-west Atlantic coasts. The genetic differentiation between oceans points to the absence of gene flow and an accelerated rate of mitochondrial evolution in the genus Mugil. 2000 The Fisheries Society of the British Isles

“…Thus, the phenomenon in P. pavoninus CR corroborates the functional signif icance of this block. Furthermore, in previous studies, more than one TAS cTAS blocks in the CR have been reported, such as two blocks in common carp, Japa nese crucian carp [15] and in two species of Rhinogo bius [47] and three blocks in Myxine glutinosa [48]. Generally, only one block exerts as the termination signal, however, there is no pertinent explanation for the issue of which one of these blocks functions to date.…”

The complete mitochondrial genome of peacock sole Pardachirus pavoninus (Pleuronectiformes: Soleidae) and comparative analysis of the control region among 13 soles

et al. 2015

The complete mitogenome of the peacock sole Pardachirus pavoninus (Lacepède, 1802) was determined. The total length is 16536 bp, containing 13 protein coding genes, 22 tRNA genes and two rRNA genes, as well as one control region (CR). The L strand replication origin (O L ), which is typically located in the WANCY cluster, is lost in P. pavoninus. The gene arrangement is identical to that in most teleosts. Com parison of the CR sequences among 13 soles reveals that a 211 bp fragment at the 5' end of the CR is lost in the P. pavoninus mitogenome, responsible for its short sequence with a length of 872 bp. All typical conser vative blocks (TAS, CSB F, E, D, C, B, A, CSB 1, 2, 3) are identified. Seven out of 13 soles contain tandem repeats in the CR and the possible mechanisms of their formation are discussed. These results may provide the consensus sequences of the conserved units in the sole CR as well as molecular data for phylogenetic stud ies on Soleidae and Pleuronectiformes.
