Climate change and the increasing frequency of high temperature (气候变化和高温事件频率的增加对全球作物产量构成重大威胁。为了解决这个问题，全面了解植物如何应对热冲击（HT) events are significant threats to global crop yields. To address this, a comprehensive understanding of how plants respond to heat shock (HS) is essential. Signaling pathways involving calcium (S）至关重要。涉及钙（Ca²⁺), a versatile second messenger in plants, encode information through temporal and spatial variations in ion concentration. Ca），是植物中通用的第二信使，通过离子浓度的时间和空间变化来编码信息。钙²⁺被 is detected by Ca 检测到²⁺-sensing effectors, including ch感应效应子，包括通道和结合蛋白，触发特定的细胞反应。在高温下，Cannels and binding proteins, which trigger specific cellular responses. At elevated temperatures, the cytosolic concentration of Ca 的胞质浓度²⁺ in plant cells increases rapidly, making 在植物细胞中迅速增加，使Ca²⁺表示对 signals the earliest response to HS. HS 的最早反应。
