Abstract
Climate changes disrupt environmental and soil conditions that affect ionic balance in plants, presenting significant challenges to their survival and productivity. Membrane transporters are crucial for maintaining ionic homeostasis and regulating the movement of substances across plasma and organellar membranes, particularly under abiotic stresses. Among these abiotic stress-responsive mechanisms, stomata are critical for regulating water loss and carbon dioxide uptake, reflecting a plant's ability to respond and adapt to abiotic stresses effectively. This review highlights the role of ion transporters, including both anion and cation transporters in plant abiotic stress responses. It explores the interplay between different ion channels and regulatory components that enable plants to withstand key abiotic stresses such as drought, salinity, and heat. Moreover, we emphasized the contributions of three essential types of ion channels - potassium, anion, and calcium to abiotic stress-related stomatal regulation. These ion channels orchestrate complex signaling networks that allow plants to modulate stomatal behavior and maintain physiological balance under adverse conditions. This article provides valuable molecular and physiological insights into the mechanisms of ion transport and regulation for plants to adapt to environmental challenges. Thus, this review offers a useful foundation for developing innovative strategies to enhance crop resilience and performance in an era of increasingly unpredictable and harsh climates.
