Construction of a normalized full-length cDNA library of cephalopod Amphioctopus fangsiao and development of microsatellite markers

Construction of a normalized full-length cDNA library of cephalopod Amphioctopus fangsiao and... Amphioctopus fangsiao is one of the most economically important species and has been considered to be a candidate for aquaculture. In order to facilitate its fine-scale genetic analyses, we constructed a normalized full-length library successfully and developed a set of microsatellite markers in this study. The normalized full-length library had a storage capacity of 6.9×105 independent clones. The recombination efficiency was 95% and the average size of inserted fragments was longer than 1000 bp. A total of 3440 high quality ESTs were obtained, which were assembled into 1803 unigenes. Of these unigenes, 450 (25%) were assigned into 33 Gene Ontology terms, 576 (31.9%) into 153 Kyoto Encyclopedia of Genes and Genomes pathways, and 275 (15.3%) into 22 Clusters of Orthologous Groups. Seventy-six polymorphic microsatellite markers were identified. The number of alleles per locus ranged from 4 to 17, and the observed and expected heterozygosities varied between 0.167 and 0.967 and between 0.326 and 0.944, respectively. Twelve loci were significantly deviated from Hardy-Weinberg equilibrium after Bonferroni correction and no linkage disequilibrium was found between different loci. This study provided not only a useful resource for the isolation of the functional genes, but also a set of informative microsatellites for the assessment of population structure and conservation genetics of A. fangsiao. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Ocean University of China Springer Journals
