Ion homeostasis is an essential strategy for mitigating drought-induced damage in plants. Drought disrupts the balance of anions and cations, thereby affecting water transport in the plasma membrane and tonoplast. This, in turn, alters the turgor pressure in guard cells and ultimately leads to stomatal closure. The production of abscisic acid (ABA) is rapidly triggered in response to drought, which serves to regulate stress responses and activate signaling cascades. ABA promotes the efflux of K+ ions from guard cells, leading to stomatal closure, and induces the accumulation of proline. Proline is a widely distributed compatible solute that accumulates in plants during adverse environmental conditions, and plays an important role in enhancing plant stress tolerance. Proline has multifaceted functions in adaptation, recovery, and signaling in plants, particularly in response to stress
