title: Isolation and characterization of novel genomic and EST-SSR markers in Coreoperca whiteheadi Boulenger and cross-species amplification.
abstract: 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.
