| 摘 要： | 为了探索生长因子受体结合蛋白2（GRB2）在缢蛏生长发育中的作用，本实验基于缢蛏转录组文库，利用SMART RACE技术克隆缢蛏GRB2（Sc-GRB2）基因的cDNA全长序列，分析其在不同组织和发育时期的表达差异，并在外显子中进行了SNP位点筛选。结果表明，Sc-GRB2基因cDNA全长1 223 bp，开放阅读框711 bp，编码236个氨基酸；氨基酸序列比对发现，缢蛏与文蛤、泥蚶等双壳贝类同源性较高（64%、59%），而与其他物种的同源性为45%~58%，表明GRB2基因比较保守；不同组织的荧光定量PCR （qRT-PCR）结果显示，Sc-GRB2基因在缢蛏7个组织中均有表达，其中足中的表达量极显著地高于其他6个组织（P<0.01）；在8个发育时期的表达差异分析发现，该基因在稚贝期表达量极显著地高于其他7个时期（P<0.01）。SNP位点筛选结果表明，在Sc-GRB2基因的外显子区域共发现11个SNP位点。

| Abstract: | To explore the molecular structure and biological function of GRB2 in Sinonovacula constricta(Sc-GRB2), its cDNA was cloned by SMART RACE techniques, then the bioinformatics, SNPs in exon and expression profiles in different tissues and developmental stages were analyzed. The results indicated that the full length cDNA of Sc-GRB2 gene was 1 223 bp, containing a complete 711 bp ORF encoding 236 amino acids. Comparisons of animal acid sequence, Sc-GRB2 has high homology with bivalves of Meretrix meretrix and Tegillarca granosa (64% and 59%). Sc-GRB2 has homologous with others share 45%-58% similarity, it indicate GRB2 is relatively conservative. The result of qRT-PCR in different tissues showed that Sc-GRB2 expressed in all seven tissues, the expression of foot was extremely significantly higher than others (P<0.01). The relative expression in different stages revealed that the expression of juvenile clams was extremely significantly higher than other stages (P<0.01). A total of 11 SNPs in the exon of Sc-GRB2 were identified. |
