Temperature is an essential physical factor that affects the plant life cycle. Almost all plant species have evolved a robust signal transduction system that enables them to sense changes in the surrounding temperature, transduce, and accordingly adjust their metabolism and cellular functions to avoid heat stress-related damage. Wheat (Triticum aestivum), as a cool-season crop, is very sensitive to heat stress. Any increase in the ambient temperature, especially at reproductive and grain-filling stages, can cause a drastic wheat yield loss. Heat stress causes lipid peroxidation due to oxidative stress, resulting in damage of thylakoid membranes and disruption of their function, and ultimately decreases photosynthesis and crop yield. The cell membrane/plasma membrane plays prominent roles as an interference system that perceives and translates the changes in environmental signals into intracellular responses. Thus, membrane lipid composition is a critical leap for heat stress tolerance or susceptibility in wheat. In this review, we elucidate the possible involvement of calcium influx as an early heat stress-responsive mechanism in wheat plants. In addition, the physiological implications underlying the changes in lipid metabolism under high-temperature stress in wheat and other plants species will be discussed. In-depth knowledge about wheat lipid reprogramming can help in developing heat-tolerant wheat varieties, and provide approaches to solve the consequences of global climate change.

热感测和脂质重编程作为小麦热应激反应的信号开关。

温度是影响植物生命周期的重要物理因素。几乎所有植物物种都进化了一种强大的信号转导系统，该系统使它们能够感应周围温度的变化，进行转导并相应地调节其新陈代谢和细胞功能，从而避免与热应激相关的损害。小麦（小麦），作为凉季作物，对热胁迫非常敏感。环境温度的任何升高，特别是在生殖和籽粒充实阶段，都可能导致小麦单产大幅下降。热应激由于氧化应激而导致脂质过氧化，从而导致类囊体膜受损并破坏其功能，并最终降低光合作用和农作物产量。细胞膜/质膜作为干扰系统起着重要的作用，该系统感知并将环境信号的变化转化为细胞内反应。因此，膜脂质组成是小麦耐热胁迫或敏感性的关键飞跃。在这篇综述中，我们阐明了钙流作为小麦植物早期热应激反应机制的可能参与。此外，将讨论小麦和其他植物在高温胁迫下脂质代谢变化的生理意义。对小麦脂质重编程的深入了解可以帮助开发耐热小麦品种，并提供解决全球气候变化后果的方法。
