Abstract:
Abiotic stressors, including drought, salt, cold, and heat, profoundly impact plant growth and development, forcing elaborate cellular responses for adaptation and resilience. Among the crucial orchestrators of these responses is the CBL-CIPK pathway, comprising calcineurin B-like proteins (CBLs) and CBL-interacting protein kinases (CIPKs). While CIPKs act as serine/threonine protein kinases, transmitting calcium signals, CBLs function as calcium sensors, influencing the plant\'s response to abiotic stress. This review explores the intricate interactions between the CBL-CIPK pathway and plant hormones such as ABA, auxin, ethylene, and jasmonic acid (JA). It highlights their role in fine-tuning stress responses for optimal survival and acclimatization. Building on previous studies that demonstrated the enhanced stress tolerance achieved by upregulating CBL and CIPK genes, we explore the regulatory mechanisms involving post-translational modifications and protein-protein interactions. Despite significant contributions from prior research, gaps persist in understanding the nuanced interplay between the CBL-CIPK system and plant hormone signaling under diverse abiotic stress conditions. In contrast to broader perspectives, our review focuses on the interaction of the pathway with crucial plant hormones and its implications for genetic engineering interventions to enhance crop stress resilience. This specialized perspective aims to contribute novel insights to advance our understanding of the potential of the CBL-CIPK pathway to mitigate crops\' abiotic stress.
摘要:
非生物应激源,包括干旱,盐,冷,和热量,深刻影响植物的生长发育,强迫复杂的细胞反应以适应和复原力。这些反应的关键协调机制是CBL-CIPK途径,包含钙调磷酸酶B样蛋白(CBL)和CBL相互作用蛋白激酶(CIPK)。而CIPKs作为丝氨酸/苏氨酸蛋白激酶,传递钙信号,CBLs作为钙传感器,影响植物对非生物胁迫的反应。这篇综述探讨了CBL-CIPK途径与植物激素如ABA之间的复杂相互作用。生长素,乙烯,和茉莉酸(JA)。它强调了它们在微调应激反应以获得最佳生存和适应中的作用。基于先前的研究,证明了通过上调CBL和CIPK基因来增强胁迫耐受性,我们探索了涉及翻译后修饰和蛋白质-蛋白质相互作用的调节机制。尽管先前的研究做出了重大贡献,在理解不同非生物胁迫条件下CBL-CIPK系统与植物激素信号传导之间细微差别的相互作用方面仍然存在差距。与更广泛的观点相反,我们的综述重点是该途径与关键植物激素的相互作用及其对基因工程干预以增强作物抗逆能力的影响。这个专门的观点旨在提供新的见解,以促进我们对CBL-CIPK途径减轻作物非生物胁迫的潜力的理解。
