摘要: 滞育是昆虫逃避不利环境条件的基本方式之一, 益虫的合理利用和害虫的综合治理, 都离不开对滞育调控机理的研究。滞育可以诱导一些基因表达模式的改变, 如热休克蛋白基因的差异表达, 导致昆虫抗逆性增强。本文综述了与昆虫滞育关联的热休克蛋白的研究概况, 从热休克蛋白与滞育的关联、 不同虫态滞育期间热休克蛋白基因的差异表达和滞育相关的蛋白质组学研究几个方面进行了概述。与其他的胁迫反应均诱导热休克蛋白同步上调表达不同, 热休克蛋白在不同种类昆虫以及同种昆虫的不同滞育生理阶段的表达模式差别很大。热休克蛋白在滞育期间的表达是决定越冬抗逆性和存活的重要因子之一。本文可为昆虫滞育如何应答环境条件刺激的研究提供参考信息。

Abstract: Diapause is one of the primary developmental pathway for insects to escape from unfavorable environment. Knowledge of diapause regulation is essential for rational use of beneficial insects and development of effective pest management strategies. Diapause evokes a unique pattern of gene expression, such as heat shock proteins (Hsps) and acquisition of increased tolerance to environmental stresses. The purpose of this review is to consider the advance on heat shock proteins related to insect diapause, including the relationship between diapause and heat shock proteins, differential expression of heat shock protein gene at different life stages during diapuase and the comparative proteomic analysis between diapause and non-diapause individuals. Unlike other common stress responses that elicit synchronous up-regulation of all Hsps, however, expression of Hsps is different during diapause in different species. The up-regulation of Hsps during diapause is an important factor contributing to overwintering defense strategy and survival. This review may provide some reference to understanding the mechanisms of diapausing insect response to environmental stimuli.
