Abstract

Abscisic acid (ABA) plays a series of significant physiology roles in higher plants including but not limited to promote bud and seed dormancy, accelerate foliage fall, induce stomatal closure, inhibit growth and enhance resistance. Recently, it has been revealed that ABA also has an important regulator role in the growth, development and ripening of fruit. In higher plants ABA is produced from an indirect pathway from the cleavage products of carotenoids. The accumulation of endogenous ABA levels in plants is a dynamic balance controlled by the processes of biosynthesis and catabolism, through the regulation of key ABA biosynthetic gene and enzyme activities. It has been hypothesized that ABA levels could be part of the signal that trigger fruit ripening, and that ABA may play an important role in the regulation of ripening and senescence of both non-climacteric and climacteric fruit. The expensive costs of natural ABA and labile active ABA for its chemical synthesis limit its application in scientific research and agricultural production. These findings that ABA has various of important roles in the regulation of growth and development, quality formation, coloring and softening, ripening and senescence of fruit, are providing opportunities and challenges for Horticultural Science. This is to elucidate the specific mechanism of response and biosynthesis, signal transduction, and receptor recognition of ABA in fruit, employing comprehensive research methods, such as molecular biology, plant physiology and molecular genetics. Further and more in-depth research about ABA has a great, realistic significance for knowing the mechanisms behind the process of fruit ripening.
