摘要/Abstract

摘要： 低温胁迫对植物的生长与发展构成了一大非生物威胁，涵盖了冷害与冻伤两种主要形式。植物形成了复杂的低温应答机制以响应持续的低温环境，从低温信号的检测到冷敏感基因的激活。这一过程因遗传背景的多样性和基因组数据的不完整性而成为研究焦点。关于植物在低温胁迫条件下的生理、代谢调整、冷敏感基因的筛选及识别、低温信号检测与传递机制、功能性基因激活与其表达模式以及相关调节机制等方面的研究取得了显著进展。特别是某些蛋白被认为是感知低温胁迫的关键，其通过特定信号激活相关因子，进而引发对冷敏感的基因表达的一系列反应。除了依赖特定因子的低温应对机制外，这些信号路径与其他路径的相互作用也有助于增强植物的抗寒能力。本文概述了植物应对低温胁迫的较新研究进展以及增强植物冷抗性的策略，并对未来的研究方向进行了展望。
