    A Central Role of Abscisic Acid in Drought Stress

    This amino acid is involved in elevation of the cell turgor and hence in maintaining the osmotic balance under drought stress conditions (Wächter et al., 2003). This role of Pro and other osmoprotectants in drought adaptation requires ABA signaling, since ABA-deficient mutants accumulate Pro to much lower levels when raised under drought or salt stress conditions (
