交配对棉铃虫嗅觉相关基因表达的影响
Effect of mating on expression of olfaction-related genes in Helicoverpa armigera
摘要
Abstract
Olfaction influences various behaviors of insects,including feeding,mating,and oviposition.However,the state of olfactory system is dynamic and adjusted according to the insect's physiological state.Mating is a crucial behavior in the life cycle of insects,leading to significant physiological changes.Previous researches have demonstrated that mating can affect olfactory perception in moths,while the underlying mechanisms remain unclear.This study investigated the impact of mating on expression of olfaction-related genes in the agricultural pest Helicoverpa armigera through transcriptome sequencing and qPCR analysis of the gene expression in antennae,labial palp,and proboscis of mated and virgin males and females.The results revealed significant changes in the expression levels of certain numbers of olfactory genes across tissues,indicating that such expression changes may lead to the changes of olfactory perception and behavior associated with mating.This research provides a molecular-level insight into the effects of mating on olfaction in H.armigera,laying a foundation for further exploration of olfactory plasticity and regulatory mechanisms.关键词
