摘要:
[目的]本文旨在鉴定重要农业害虫双委夜蛾(Athetis dissimilis Hampson)的信息素结合蛋白(pheromone binding protein,PBP)基因,并分析其序列和组织表达特征,为进一步研究双委夜蛾的嗅觉感受机制奠定基础。[方法]基于双委夜蛾触角转录组数据获得3个PBP基因(AdisPBP1、AdisPBP2、AdisPBP3)的全长序列,通过RT-PCR对3个基因进行克隆和验证,利用RT-qPCR对3个基因在雌、雄成虫的组织表达谱进行分析。[结果]从双委夜蛾触角中克隆3个PBP基因的cDNA序列,3个基因AdisPBP1、AdisPBP2AdisPBP3分别编码166、169和164个氨基酸,并具有6个保守的半胱氨酸、N端1个信号肽序列等该类基因的典型特征。聚类分析表明:这3个基因分别被聚到3个不同的PBP分支中,且均与同属害虫二点委夜蛾(Athetis lepigone)的相应PBP最近。表达谱分析显示:3个基因均仅在雌、雄虫触角中高表达;AdisPBP1在雄性触角的表达量显著高于雌性触角,而AdisPBP2AdisPBP3在两性触角中的表达量相似;3个基因雄、雌蛾触角的表达量差异(雄∶雌)分别为1.84、1.14和0.95,暗示其在性信息素及其他气味感受中的不同作用。[结论]克隆了双委夜蛾3个PBP基因的cDNA全长序列,明确了3个基因的组织表达谱及雌、雄表达差异,对3个PBP基因的可能功能进行了讨论。
Abstract:
[Objectives] This study aims to identify the pheromone binding protein (PBP)genes and clarify their tissue expression pattern, provide basis for further study on the olfactory mechnism of Athetis dissimilis. [Methods] The full-length cDNA of three PBP genes (AdisPBP1, AdisPBP2, AdisPBP3)from A. dissimilis were obtained by analyzing the antennae transcriptomic data and further verified by RT-PCR experiments. The tissue expression patterns of three PBP genes in male and female adults were analyzed by RT-PCR and RT-qPCR. [Results] Three PBP genes were cloned from the antennae of A. dissimilis adults, which were named AdisPBP1, AdisPBP2, AdisPBP3, respectively. The cDNA sequence of the three PBP genes encoded 166, 169 and 164 amino acids, respectively. The encoded proteins of the three genes had typical characteristics of PBP, including an N-terminal signal peptide and six conserved cysteines. Phylogenetic analysis revealed that the three genes were clustered into three distinct PBP groups and had the highest homology with the PBP of Athetis lepigone. Expression patterns investigation revealed that the three genes were highly expressed in adult antennae of both males and females. The relative expression levels of AdisPBP1, AdisPBP2 and AdisPBP3 in the antennae of male adults were 1.84, 1.14 and 0.95 times as high as those in the antennae of female adults, respectively. [Conclusions] Three A. dissimilis PBP genes were identified, their tissue and sex expression patterns were determined, and their functions were discussed.
