| 英文摘要 | The basic helix-loop-helix(b HLH) genes encode a large superfamily of transcription factors in the Pacific oyster( Crassostrea gigas), and play a very important role in regulation of growth and development. To investigate the oyster growth traits and the associations with b HLH genes variations, we analyzed the gene polymorphisms-traits association in a wild population, and confirmed the results in another independent wild population by targeted gene re-sequencing and SNPshot analysis. After screening the single nucleotide polymorphisms(SNPs) in three candidate genes of the b HLH family(88 b HLH genes in two wild oyster populations in total), we identified the allele Cg Lobl HLH4-T/G located in the exon of the Cg Lobl HLH4 gene. This allele is a non-synonymous mutation(Phe/Leu) with an extremely significant association with shell width( P <0.01) and allele G is beneficial to shell width. This SNP on the Cg Lobl HLH4 gene might have a potential value as a genetic marker of growth traits that could be used in breeding in C. gigas in the future. |
