   INTRODUCTION
 
Abscisic acid (ABA) was first discovered in the 1960s, initially under the names of either dormin or abscissin in young cotton fruits and sycamore leaves. Since then, this hormone has been found in a great number of plant species and appears to be of universal occurrence among vascular plants and mosses. The most documented role of ABA is in seed maturation processes, acquisition of desiccation tolerance and dormancy. All of these traits in seed development have important applications for crop species due to the widespread problem of pre-harvest sprouting (the germination of the physiologically mature grain on the parent plant prior to harvest) that occurs in many regions of the world. Also, during vegetative growth, ABA is the key hormone that confers tolerance to environmental stresses, most notably drought and high salinity, thereby permitting plants to colonize ecological niches where water availability is limited or sporadic. With water shortage predicted . . . [Full Text of this Article]
