Abscisic acid (ABA) is a phytohormone that is essential for plant growth and development and is involved in the integration of multiple stress signals as well as the modulation of downstream stress responses. Plants constantly alter ABA levels in response to changing physiological and environmental circumstances.

ABA is a common plant hormone that is produced in nearly all cells that include chloroplasts or amyloplasts.
