The phytohormone abscisic acid (ABA) plays regulatory roles in a host of
physiological processes in all higher as well as in lower plants (Davies and Jones, 1991; Zeevaart and Creelman, 1988). Abscisic acid mediates stress tolerance responses in higher plants, is a key signal compound that regulates stomatal aperture and, in concert with other plant signaling compounds, is implicated in mediating responses to pathogens and wounding.
In seeds, ABA promotes seed development, embryo maturation, synthesis of storage products (proteins and lipids), desiccation tolerance, is involved in maintenance of dormancy (inhibition of germination), and apoptosis (Zeevaart and Creelman, 1988; Davies and Jones, 1991; Thomas, 1993; Bethke et al 1999). As well, ABA affects plant architecture, including root growth and morphology, and root-to-shoot ratios.
