摘要: The oyster insulin-related peptide (oIRP) is known in other organisms to play important roles growth control and carbohydrate homeostasis. Polymorphisms of the oIRP gene were evaluated for associations with performance 271 Crassostrea gigas individuals from a diallel cross among three strains C. gigas. Thirty-one single nucleotide polymorphisms (SNPs) revealed 1.5 kb gene, six them significantly associated (P < 0.05), particularly T1358G G1437A which highly correlated all five traits (shell height, shell length, width, body mass soft-tissue mass) 0.01). Moreover, haplotypes analysis that H7 (ATGTGA) H8 (ATGTTA) might be most advantageous traits. results demonstrated could influence have potential applications future genetic improvement
