Project description:We described and characterized 11 expressed sequence tag (EST)-derived simple sequence repeats (SSR) and seven genomic (G)-derived SSRs in Coreoperca whiteheadi Boulenger. The EST-SSRs comprised 62.2% di-nucleotide repeats, 32.2% tri-nucleotide repeats and 5.5% tetra-nucleotide repeats, whereas the majority of the G-SSRs were tri-nuleotide repeats (81.4%). The number of alleles for the 18 loci ranged from 3 to 6, with a mean of 3.8 alleles per locus. The observed (Ho) and expected heterozygosities (He) values ranged from 0.375 to 1.000, and 0.477 to 0.757, respectively. The polymorphic information content (PIC) values ranged from 0.466 to 0.706. The mean values number of alleles, Ho, He, and PIC of EST-SSRs were higher than those of the G-SSRs. Four microsatellite loci deviated significantly from Hardy-Weinberg equilibrium (HWE) after Bonferroni correction and no significant deviations in linkage disequilibrium (LD) were observed. These loci are the first to be characterized in C. whiteheadi and should be useful in the investigation of a genetic evaluation for conservation. Compared with 11 loci in C. whiteheadi, 37 potential polymorphic EST-SSRs were found in Siniperca chuatsi (Basilewsky), which will provide a valuable tool for mapping studies and molecular breeding programs in S. chuatsi.
Project description:Based on small samples (exemplars) analyzed with morphological methods, including detailed descriptions and illustrations, this study treats primarily the Zuphium genus-group in the Western Hemisphere, which comprises two precinctive genera: Coarazuphium Gnaspini, Vanin & Godoy, 1998 (type species Parazuphium tessai Godoy & Vanin, 1990) and Zuphioides gen. n. (type species Zuphium mexicanum Chaudoir, 1863). The genus Coarazuphium includes six troglobitic species from Brazilian caves, and one probably hypogaeic (troglophilic) species from the mountains of Oaxaca, in Mexico (Coarazuphium whiteheadi, sp. n., type locality, ridge top, in western Oaxaca, Mexico, at 2164 m, 35 km north of San Pedro Juchatengo, 16.462N, 97.010W). The epigaeic genus Zuphioides includes 23 species, with its geographical range extended from Neotropical temperate Argentina in southern South America, northward through the tropics to north temperate southeastern Canada, in the Nearctic Region. Keys are provided to the species of Coarazuphium and to thegenera of Western Hemisphere Zuphiini.
