    • 摘要: 才女虫系隐居目、海稚虫科、才女虫属的多毛类环节动物,可栖息于任何海域的潮间带至深水区。才女虫可以通过分泌酸性物质腐蚀如虾夷扇贝、马氏珠母贝、九孔鲍、杂色鲍和菲律宾蛤仔等贝类的贝壳,并且当虫体钻穿贝壳达到软体部位后,可以使“寄生”处的组织周围发生炎症,局部形成脓肿和溃疡,引起继发细菌性溃疡,同时产生一种特殊的臭味,降低贝类的品质和价值,严重时可导致贝类死亡,给贝类养殖业带来重大损失。除对贝类养殖带来危害以外,才女虫对虾蟹类的苗种生产造成的危害同样不可小觑,据报道,育苗池内一旦有才女虫滋生。

    • 摘要: Myostatin is an important member of the transforming growth factor (TGF) family that functions to reg-ulate muscle development and growth in animals, The purpose of this study was to characterize and predict func-tion of the myostatin gene of Haliotis diversicolor supertexta which is an important aquaculture shellfish. In this study, the myostatin (Hs-MSTN) cDNA of H. diversicolor supertexta were cloned and characterized by rapid amp-lification cDNA ends (RACE) methods. The full length of Hs-MSTN cDNA sequence consists of 3 755 bp contain-ing a 5′ untranslated region (UTR) of 324 bp, a 3′ UTR of 1 985 bp, and an open reading frame of 1 446 bp encod-ing a protein with 481 amino acid residues, with a calculated molecular mass of 54.96 ku, and the theoretical iso-electric point of 9.41, The structure of Hd-MSTN included a putative signal peptide (1-17 aa), a TGF-β propeptide domain (157-367 aa) and a conserved TGF-β domain (379-481 aa). Multiple sequence alignment results revealed conservation of the RRPR proteolytic site and nine conserved cysteines of the Hs-MSTN with MSTN from other animals, and two propeptide proteolytic sites RQRR (120-124 aa) and RYRR (235-239 aa) were found. Phylogen-etic analysis showed that the Hs-MSTN gene was clustered in the same subgroup with the H. rufescens, Quantitat-ive real-time PCR detection results indicated that the Hs-MSTN genes were expressed widely in adductor muscle, mantle, gonad, liver, gill, foot and the highest expression level was observed in the adductor muscle, mantle, foot, and Hs-MSTN transcript was widely detected in early developmental stages: unfertilized egg, fertilized egg, 4-cell embryos, 8-cell embryos, gastrulae, larvae, juvenile stage, and the higher in fertilized egg, in 4-cell embryos and 8-cell embryos and the expression level increases in gastrulae, larvae and decreases in juvenile stage. Our results in-dicate that MSTN is involved in muscle growth regulation of H. diversicolor supertexta.%肌肉生长抑制素(MSTN)是转化生长因子β超家族(TGF-β)中参与动物肌肉生长的重要调控因子.为了解MSTN基因在九孔鲍中的功能,本研究采用cDNA末端快速扩增(RACE)技术从九孔鲍右侧壳肌中获得了MSTN基因cDNA全长,并运用实时荧光定量PCR (qRT-PCR)技术检测了MSTN在各组织和发育时期的表达水平.结果显示,九孔鲍cDNA全长3 755 bp,其中5′非编码区(5′UTR)324 bp,3′非编码区(3′UTR)1 985 bp,开放阅读框(ORF) 1 446 bp,编码481个氨基酸,分子质量为54.96 ku,理论等电点pI为9.41;具有N端信号肽(1~17 aa)、 TGF-β前肽区域(157~367 aa)和成熟肽区域(379~481 aa),以及蛋白酶水解位点RRPR (364~368 aa)和C端生物活性区9个保守的半胱氨酸残基,符合TGF-β超家族蛋白典型结构特征,且预测到2个新的蛋白酶水解位点RQRR (120~124 aa)、RYRR (235~239 aa).系统进化树结果显示,九孔鲍MSTN基因和红鲍MSTN基因聚为一支.qRT-PCR结果表明,九孔鲍MSTN基因在检测的6个组织中均表达,且在足、右侧壳肌、外套膜中高表达,在鳃、性腺、肝脏中低表达;在检测的7个发育时期均表达且在受精卵、原肠胚、稚鲍时期高表达,在卵、4细胞期、8细胞期、幼鲍时期表达量较低.研究表明MSTN基因可能在九孔鲍肌肉生长中具有重要作用.

    • 摘要: 采用中心复合设计和响应曲面法研究了盐度和胁迫时间对九孔鲍(Haliotis diversicolor supertexta)α-淀粉酶基因表达量影响的联合效应,旨在为九孔鲍盐度驯化及海区推广提供指导.实验设定盐度范围为22~40,时间范围为0~72 h,建立了盐度、胁迫时间与α-淀粉酶基因表达量之间关系的定量模型,并通过分析明确了盐度和胁迫时间的最优组合.结果表明,盐度对九孔鲍α-淀粉酶基因表达量影响的一次效应不显著(P>0.05),而二次效应极显著(P<0.01),说明盐度与九孔鲍d-淀粉酶基因表达量之问为非线性关系.随盐度升高,淀粉酶基因表达量呈先上升后下降的变化趋势,当盐度为31时淀粉酶基因表达量最大,此时九孔鲍消化能力最强.胁迫时间对淀粉酶基因表达量影响的一次效应显著(P<0.05),二次效应不显著(P>0.05),表明胁迫时间与九孔鲍α-淀粉酶基因表达量之间呈线性关系,即随着胁迫时间的延长,淀粉酶基因从开始低水平表达逐渐升高并恢复至正常表达水平.盐度和胁迫时间之间不存在交互作用.对实验结果建立模型可知,α-淀粉酶基因表达回归模型达极显著水平(P<0.05),且失拟项不显著(JP>0.05),表明实验拟合出的方程有效.回归方程的决定系数为80.05%,校正系数65.80%,预测系数50.18%,表明方程拟合度较好,模型选择较为恰当,可以为不同盐度和胁迫时间诱导下的淀粉酶基因表达量变化提供参考依据.%Haliotis diversicolor supertexta is mainly distributed in coastal waters off southern China and is a warmwater,economically important shellfish.H.diversicolor supertexta is characterized by rapid growth,a short breeding cycle,suitability for high density cultivation,and is nutritious,so there is high demand among consumers.Guangdong is often affected by typhoons,so more rain falls there than in other provinces.Sea salinity drops when rainfall increases,and the osmotic pressure in aquatic animals varies because of salinity changes,which can result in massive mortalities of abalone.H.diversicolor supertexta is a local species in Guangdong,making it particularly susceptible.Response surface methodology (RSM) is a collection of statistical and mathematical techniques to optimize a process.This methodology generates an empirical mathematical model that defines the effect of an independent variable on a response of interest to optimize the response.RSM has been applied in ecotoxicological studies of marine bivalve larvae and to investigate the effects of environmental variables on embryonic and larval development.RSM has not been used in any gastropod nutritional studies.In this study,the synergistic effects of salinity and stress duration on alpha-amylase gene expression were assessed using central composite design and RSM.The results show that the linear effects of salinity on alpha-amylase gene expression were not significant (P>0.05),but the linear effect of stress duration was significant (P<0.05),suggesting that expression of the amylase gene was affected by stress duration.In addition,the quadratic effects of salinity on amylase gene expression were significant (P<0.05),but the quadratic effects of stress duration on amylase gene expression were not significant (P>0.05).No synergism was detected between salinity and stress duration.The RSM model equation for the relationship between amylase gene expression and the two factors was established (R2=80.05%).The Adj.R2 value was 65.80%,and the Pre.R2 values was 50.18%,suggesting a good model fit for prediction.Maximal amylase gene expression was observed when salinity was 31,and stress duration was 36 h.H.diversicolor supertexta is affected by many factors,as it is cultured in a marine environment.Additional factors should be studied in the future.

    • 摘要: We cloned the alpha-amylase gene cDNA of Haliotis diversicolor supertexta by rapid amplification of cDNA ends method (RACE) and reverse transcription polymerase chain reaction (RT-PCR) to analyze its tissue expression and correlation with growth traits.The results show that the full length of alpha-amylase gene cDNA was 2 260 bp with an open reading frame (ORF) of 2 088 bp encoding 695 amino acids.The alpha-amylase contained a signal peptide with 18 amino acid residues (MWAQYGIVSALLVLSASA).Two functional structure domains (domain A,domain C) were found in the protein of alpha-amylase.Domain A contained one catalytic center between 28th and 396th amino acids.The alpha-amylase mRNA expression in seven tissues (adductor muscle,intestine,digestive gland,stomach,mantle,rostral,foot) was observed,highest in stomach (326.803) and lowest in mantle (0.35).Significant difference was found in the expression of alpha-amylase between digestive and non-digestible tissues (P < 0.05).Significant positive correlation existed between alpha-amylase gene expression and growth traits (P <0.05).%实验采用cDNA末端快速扩增(RACE)和反转录聚合酶链式反应(RT-PCR)技术对九孔鲍(Haliotis diversicol-or supertexta)α-淀粉酶基因cDNA进行克隆,并分析该基因的组织表达及其与生长性状的相关性.结果表明,九孔鲍α-淀粉酶基因cDNA全长为2 260 bp,其中开放阅读框长度为2 088 bp,共编码695个氨基酸.经SingalP分析,α-淀粉酶多肽链中含有信号肽结构,且长度为18个氨基酸(MWAQYGIVSALLVLSASA),由该多肽链折叠成的三级结构中含有domain A、domain C 2个结构域,并且在domain A第28~第396氨基酸处存在催化中心.该基因在九孔鲍右侧壳肌、肠、肝脏、胃、外套膜、吻、腹足7种组织中均有不同程度表达.其中在胃中表达量最高,表达量高达326.803;而在外套膜中表达量最低,表达量仅为0.35.经ANOVA分析,消化组织与非消化组织间的α-淀粉酶基因表达量存在显著差异(P<0.05).α-淀粉酶基因mRNA表达量与生长性状呈显著正相关(P<0.05).
