Abiotic stress is the major threat confronted by modern-day agriculture. Salinity is one of the major abiotic stresses that influence geographical distribution, survival, and productivity of various crops across the globe. Plants perceive salt stress cues and communicate specific signals, which lead to the initiation of defence response against it. Stress signalling involves the transporters, which are critical for water transport and ion homeostasis. Various cytoplasmic components like calcium and kinases are critical for any type of signalling within the cell which elicits molecular responses. Stress signalling instils regulatory proteins and transcription factors (TFs), which induce stress-responsive genes. In this review, we discuss the role of ion transporters, protein kinases, and TFs in plants to overcome the salt stress. Understanding stress responses by components collectively will enhance our ability in understanding the underlying mechanism, which could be utilized for crop improvement strategies for achieving food security.
非生物胁迫是现代农业面临的主要威胁。盐胁迫是影响全球各种作物地理分布、存活和生产力的主要非生物胁迫之一。植物感知盐胁迫信号并传递特定信号，从而引发针对盐胁迫的防御反应。胁迫信号传导涉及转运蛋白，这些转运蛋白对于水分运输和离子稳态至关重要。各种细胞质成分如钙和激酶对于引发分子反应的细胞内任何类型的信号传导都至关重要。胁迫信号传导会注入调节蛋白和转录因子（TFs），这些因子会诱导胁迫响应基因。在本综述中，我们讨论了离子转运蛋白、蛋白激酶和转录因子在植物克服盐胁迫中的作用。通过这些成分共同理解胁迫反应将增强我们理解潜在机制的能力，这可用于实现粮食安全的作物改良策略。
