Maintaining ion homeostasis is a crucial adaptation strategy employed by plants to mitigate the effects of drought. When subjected to drought stress, the balance of anions and cations in plants is disrupted, causing changes in turgor pressure in guard cells through water transport systems in the plasma membrane and tonoplast, ultimately leading to stomatal closure. The plant hormone ABA, which is rapidly produced in response to drought and salinity, plays a vital role in regulating stress responses and triggering a series of signaling cascades. ABA induces the efflux of K+ ions from guard cells, resulting in a loss of turgor pressure and subsequent stomatal closure. Research has shown that the accumulation and mobilization of Pro is linked to improved tolerance to drought stress. Furthermore, the application of exogenous GB leads to increased accumulation of endogenous osmolytes such as free Pro and GB, helping to maintain ion homeostasis under stressful conditions
