Abstract
Phytohormone abscisic acid (ABA) regulates the growth and development
of plants as well as their response to environmental changes. Recently, the regulations
of ABA during fruit ripening and stress resistance were discovered in two types of
fruits (climacteric and non-climacteric fruits). However, it is challenging to understand
the physiological, biochemical, and molecular biological mechanisms in fruit ripening
and stress response controlled by ABA. ABA is involved in fruit development
processes, including young fruit growth, fruit ripening onset, ripening process and
quality formation. Meanwhile, ABA plays an important role in fruit adapting to
environmental stresses. ABA works through the adjustment of its concentration and
signal transduction. This review summarizes the current knowledge regarding ABA in
the regulation of fruit development and ripening as well as in responses to
environmental stresses.
