Abstract

Global warming impacts crop production and threatens food security. Elevated temperatures are sensed by different cell components. Temperature increases are classified as either mild warm temperatures or excessively hot temperatures, which are perceived by distinct signaling pathways in plants. Warm temperatures induce thermomorphogenesis, while high-temperature stress triggers heat acclimation and has destructive effects on plant growth and development. In this review, we systematically summarize the heat-responsive genetic networks in Arabidopsis and crop plants based on recent studies. In addition, we highlight the strategies used to improve grain yield under heat stress from a source-sink perspective. We also discuss the remaining issues regarding the characteristics of thermosensors and the urgency required to explore the basis of acclimation under multifactorial stress combination.

摘要

全球变暖影响作物生产，威胁粮食安全。不同的细胞成分感知到温度升高。温度升高分为温和温暖的温度或过热的温度，这是由植物中不同的信号通路感知到的。温暖的温度诱导热形态发生，而高温胁迫引发热适应，并对植物的生长和发育产生破坏性影响。在这篇综述中，我们根据最近的研究系统地总结了拟南芥和作物中与热响应相关的遗传网络。此外，我们还从源库的角度强调了在热胁迫下提高谷物产量所采用的策略。我们还讨论了关于热感受器的特性以及探索多因素胁迫组合下适应基础的紧迫性方面存在的问题。
