Abstract

Abscisic acid (ABA) is an essential endogenous messenger during plant development and in stress responses. Recently, the role of ABA in both climacteric and nonclimacteric fruit ripening regulation was revealed. However, the genetic, molecular and physiological mechanisms of ABA in fruit ripening regulation is still not completely understood. ABA is involved in a wide range of fruit development processes, including fruit ripening onset, ripening process and fruit quality trait. In addition, ABA plays a significant role in responses to abiotic stress and the promotion of water efficiency in fruit. The biological effect of ABA depends on its concentration and signal transduction. This article summarises the latest discoveries of the roles of ABA in fruit development and ripening as well as in responses to abiotic stress.
