Ion homeostasis: important strategy for minimizing drought damage. Drought causes imbalance in anions/cations in plants, affecting water transport in plasma membrane/tonoplast. This leads to turgor pressure changes in guard cells, resulting in stomatal closure. ABA, rapidly produced in response to drought/salinity, regulates stress responses and induces signalling cascades. ABA promotes K+ ion efflux from guard cells, leading to stomatal closure. Pro accumulation/mobilization associated with enhanced drought tolerance. Exogenous GB application increases endogenous osmolyte accumulation (free Pro/GB) to maintain ion homeostasis under stress
