摘要: 温度是限制物种适应性分布的重要因子,决定着物种的分布和扩散区域。昆虫作为小型变温动物,对温度变化十分敏感,温度胁迫反应是其抵御极端环境的最保守的机制之一。其中表观遗传学为昆虫提供了更快的温度胁迫响应机制,与经典遗传学不同,表观遗传学在不改变DNA序列的前提下响应环境变化对基因表达产生快速而持久的影响。表观遗传调控包括DNA甲基化、组蛋白修饰、染色质重塑、非编码RNA调控等,本文主要阐述了以上四个方面在昆虫响应温度胁迫中的应用和研究进展,以探究昆虫在温度变化中的适应能力。

Abstract: Temperature is an important factor limiting the adaptive distribution of species and determines the distribution and diffusion area of species. As small poithermic animals, insects are very sensitive to temperature changes, and the temperature stress response is one of the most conservative mechanisms to resist the extreme environment. Epigenetics provides a faster response mechanism to temperature stress for insects. Different from classical genetics, epigenetics responds to environmental changes and has a rapid and lasting effect on gene expression without changing DNA sequence. Epigenetic regulation includes DNA methylation, histone modification, chromatin remodeling, and regulation of non-coding RNA, etc. This paper mainly describes the application and research progress of the above four aspects in insect response to temperature stress, so as to explore the adaptability of insects to temperature change.

Key words: temperature stress, insects, epigenetics, research progress
