Abstract: Abscisic acid (ABA) is now recognized as one of the five major plant hormones, this article mainly summarized the multiple roles of ABA in plant growth and development, abiotic stress and biotic stress, such as in plant growth and development ABA promoted organ prolapse, seed maturation and dormancy, regulated stomatal, inhibited seed germination, growth and accelerated aging, seed embryo development and flowering; In abiotic stress ABA can promote tolerance, therefore, ABA also known as stress hormones; In biotic stress its role varies according to the types of pathogenic bacteria or the different invasion methods, ABA either played positive role or negative role. Finally, the author made an expectation of the role of ABA in biotic stress, such as the dynamics involved in plant defense, mode of actions and interactions with other hormone signal needed further research.
