Abstract
Abscisic acid (ABA) was discovered in the 1950s to be a phytohormone affecting leaf abscision and bud dormancy. It was soon characterized as a sesquiterpene derived from mevalonate although certain steps of its biosynthesis in plants are still unknown (Li and Walton, 1987; Zeevaart and Creelman, 1988). Continuing work on ABA has shown that it mediates various developmental and physiological processes that affect the agronomic performance of crop plants (Austin et al., 1982; Ramagopal, 1987). These proc? esses include embryo maturation and germination as well as the response of vegetative tissues to osmotic stress (Singh et al., 1987; Zeevaart and Creelman, 1988). ABA levels increase in tissues subjected to osmotic stress by desiccation, salt, or cold (Henson, 1984; Mohapatra et al., 1988). Under these conditions, specific genes are ex? pressed that can also be induced in unstressed tissues by the application of exogenous ABA (Singh et al., 1987; Gomez et al., 1988; Mundy and Chua, 1988). Some of these genes are also expressed during the normal embryogenic program when seeds desiccate and embryos be? come dormant (Dure et al., 1981). Although different sets of ABA-responsive genes exhibit different patterns of de? velopmental and tissue-specific expression, some of them appear to be part of a general reaction to osmotic stress. This system is a normal part of the embryogenic program but is inducible in vegetative tissues at other times in the plant life cycle. Several ABA-responsive genes have now been isolated (Baker et al., 1988; Gomez et al., 1988; Marcotte et al., 1988; Mundy and Chua, 1988; Vilardell et al., 1990; Yamaguchi-Shinozaki et al., 1990). A major goal of the research discussed below is to understand the role these genes play in osmotic stress and desiccation tolerance.
