茶谷蛾(Agriophara rhombata Meyr.)触角上表达的嗅觉相关基因是其交配、寻找食物来源、寻找产卵地、避免有害化合物等行为的重要分子基础.为了研究茶谷蛾触角的嗅觉机制,分析了雌雄蛾触角功能差异,并筛选触角气味结合蛋白基因,本研究采用转录组测序和实时定量PCR技术,对茶谷蛾雌、雄蛾触角的基因表达情况进行了分析,共注释到37 666个基因,其中雌、雄蛾共有的表达基因数目为34 720个,雌蛾特有表达基因有1 739个,雄蛾特有表达基因有1 207个.在雌、雄蛾触角中共鉴定到170个化学感受相关基因,包括33个气味结合蛋白基因(odorant binding protein genes,OBPs),42个味觉受体基因(gustatory receptor genes,GRs),12 个化学感受蛋白基因(chemosensory protein genes,CSPs),52 个嗅觉受体基因(olfactory receptor genes,ORs),27 个离子型受体基因(ionotropic receptor genes,IRs),4 个感觉神经元膜蛋白基因(sensory neuron membrane protein genes,SNMPs).OBP 蛋白基因中 16 个聚集在信息素结合蛋白基因(pheromone-binding protein genes,PBPs)亚家族,14个聚集在普通气味结合蛋白基因(general odorant-binding protein genes,GOBPs)亚家族,3个聚集在触角结合蛋白基因(antennal binding protein genes,ABPs)亚家族.本研究为茶谷蛾嗅觉分子机制研究提供了线索,为茶谷蛾嗅觉机制的研究以及茶谷蛾绿色防控药剂的开发奠定了基础.
Transcriptome Sequencing Analysis of Odorant Binding Protein Genes in Anten-nae of Agriophara rhombata Meyr.
The olfactor-related genes expressed on the antennae of tea millet moth(Agrophara rhombata Meyr.)are the important mo-lecular basis for mating,finding food sources,finding spawning sites,and avoiding harmful compounds.In order to study the olfactory mechanism of antennae of tea millet moth,gene expression in the antennae of female and male moth were analyzed by transcriptome se-quencing technology and real time quantitative PCR.A total of 37 666 genes were annotated.The number of expression genes shared by the female and male moths was 34 720,1 739 specific expression genes of the female moths and 1 207 specific expression genes of the male moths.A total of 170 chemoreception-related genes were identified in the antennae of female and male moths,including 33 o-dorant binding protein genes(OBPs),42 gustatory receptor genes(GRs),12 chemosensory protein genes(CSPs),52 olfactory recep-tor genes(ORs),27 ionotropic receptor genes(IRs),and 4 sensory neuron membrane protein genes(SNMPs).Among OBPs,16 clus-tered in pheromone-binding protein genes(PBPs)subfamily,14 clustered in general odorant-binding protein genes(GOBPs)subfami-ly,3 clustered in the antennal binding protein genes(ABPs)subfamily.This study provides clues for the molecular mechanism of the olfactory sense of the Agrophara rhombata Meyr.,and lay a foundation for the research of the olfactory mechanism of the tea millet moth and the development of green control agents for the tea millet moth.
