“…Although the vertebrate mitochondrial genome is inherited as a single unit and rarely undergoes recombination, various regions exhibit markedly different substitution rates (Naylor and Brown, 1998). Consequently, regions with relatively high substitution rates (i.e., hypervariable regions) have been used to infer relatedness in taxa with shallow divergence times, while markers that exhibit slower substitution rates (e.g., 16S rRNA locus) are better suited for resolving deeper taxonomic questions (Bernardi and Crane, 1999;Pardo et al, 2005;Sturmbauer and Meyer, 1993). The analysis of a species' complete mitochondrial genome best illustrates the variability observed among loci.…”

The complete mitochondrial genome of the black surfperch, Embiotoca jacksoni: Selection and substitution rates among surfperches (Embiotocidae) The complete 16,515 bp nucleotide sequence of the mitochondrial genome was determined for the black surfperch, Embiotoca jacksoni (Perciformes: Embiotocidae). The black surfperch mitochondrial genome contains 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and the non-coding control region (Dloop), the gene order of which is identical to that observed in most vertebrates. The protein-coding gene sequences of E. jacksoni mitochondrial DNA were compared with two other embiotocid surfperches with available complete mitochondrial genomes, Cymatogaster aggregata and Ditrema temminckii. Across all mitochondrial protein-coding genes in surfperches the weighted average substitution rate was 2.079% per My and average dN/dS ratios for each protein-coding gene ranged from 0.016 in CytB to 0.608 in ND3. Substitution rates and dN/dS ratios were relatively high for ATP8 compared to other protein-coding genes. Although most protein-coding genes showed signals of purifying selection, we found evidence for positive selection in ND3 in E. jacksoni.

“…Although hybrid fish have been produced by bigeneric crossing, such as between the two sturgeons Huso huso and Acipenser ruthenus and between silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis), most hybrid fish that have been developed to date are intraspecific or interspecific (Bartley et al, 2000). Although P. olivaceus and P. stellatus belong to different families, sequence analysis of the mitochondrial 16S rDNA showed that these two families are very close to each other on the phylogenetic tree, which could explain the feasibility of hybrid production (Pardo et al, 2005;Azevedo et al, 2008). The hybrid between the female P. olivaceus and male P. stellatus showed more morphological similarity to P. stellatus; growth was improved, but the hybrid was not fertile (Nam et al, 2008).…”

ABSTRACT. An interspecific artificial hybrid was produced between two economically important aquaculture flatfish: olive flounder (Paralichthys olivaceus) and starry flounder (P. stellatus). This hybrid displays the rapid growth characteristic of the former and tolerance to low temperatures and low salinity of the latter, but the genetics of inheritance in this hybrid have not been elucidated. Polymorphic microsatellite markers developed for P. olivaceus and P. stellatus were tested to determine if these markers can be used for analysis of parentage and genetic inheritance. Multiplex PCR using two primer sets that were specific to each species produced PCR products of different sizes; these could be used for the identification of interspecific hybrids. Among the 192 primers derived from olive flounder, 25.5% of the primer sets successfully amplified genomic DNA from starry flounder, and 23% of the 56 primer sets originating from starry flounder amplified DNA from olive flounder. Analysis of genetic inheritance in the hybrid using seven of the 62 microsatellite markers common to both species demonstrated classic Mendelian inheritance of these markers in the hybrid progeny, with the exception of one locus identified as a null allele in the hybrid. These results demonstrate that cross-specific microsatellite markers can be used tools for parentage analysis of hybrid flatfish, for mapping quantitative trait loci, for marker-assisted selective breeding, and for studies of the evolution of fish.

“…Hensley & Ahlstrom (1984) en base a caracteres morfológicos, merísticos y osteológicos postulan que Paralichthyidae estaría estructurada por agrupaciones de especies que conformarían distintos grupos tipos, donde cada grupo podría estructurar una línea filética. Estos grupos serían Cyclopsetta, Pseudorhombus y Paralichthys, determinados por estudios de cariotipo y antecedentes moleculares (Berendzen & Dimmick 2002, Pardo et al 2005, Azevedo et al 2008.…”

Abstract.-An osteological description of Hippoglossina macrops, a flounder found in the Southeast Pacific, is presented.Specimens between 11 and 32 cm of total length, captured in the area of Valparaíso and Tomé (Chile) were analyzed. Observations were carried out from dissected specimens previously preserved in formalin and cleared and stained specimens for bone and cartilage. The osteological features of those specimens were then compared to H. montemaris. In general, the Hippoglossina macrops osteology have the features given for the suborder Pleuronectoidei, showing diagnostic characters of Paralichthyidae, such as a supra occipital crest inclined towards the nadiral side; metapterygoid related to the upper edge of the quadrate by cartilage and to the rear end by the hyosimplectic cartilage; subopercle with a subsequent upward extension presenting on their sides not ossified surfaces which give uniformity to the bone; fourth abdominal bone in its portion shows a fusion of the first two anal pterygiophores, are among the most important ones. Within the Paralicthyidae family, H. macrops it shares characteristics with Pseudorhombus and Paralichthys. H. montemaris specimens do not show morphological differences with H. macrops, which questioned the validity of the species. Key words: Fishes, flounder, skeletonResumen.-Se efectúa una descripción osteológica del lenguado Hippoglossina macrops, presente en el Pacífico suroriental. Se analizaron ejemplares capturados en la zona de Valparaíso y Tomé (Chile), de longitudes totales entre 11 y 32 cm. Las observaciones fueron realizadas a partir de disecciones de ejemplares conservados en formalina y de especímenes coloreados para huesos y cartílago. Se comparó las descripciones osteológicas con ejemplares de H. montemaris. En general, la osteología de Hippoglossina macrops posee los caracteres dados para el suborden Pleuronectoidei, presentando caracteres diagnósticos de Paralichthyidae, siendo los más importantes: la cresta del supraoccipital inclinada hacia el lado nadiral; metapterigoides relacionado con el borde superior del cuadrado por cartílago y en su extremo posterior con el cartílago hiosimpléctico; subopercular con prolongación ascendente posterior presentándose a sus lados superficies no osificadas que dan uniformidad al hueso; cuarto hueso abdominal en su porción presenta fusión de los dos primeros pterigióforos anales. Dentro de la familia Paralichthyidae, H. macrops comparte caracteres de Pseudorhombus y Paralichthys. Los especímenes de H. montemaris, no muestran diferencias morfológicas con H. macrops, dudando sobre la validez de esta especie.
