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 significa
