“…ABA has been identified as an endogenous signal that is involved in the regulation of several environmentally induced genes (3,6,17). Boussiba et al (2) proposed that ABA is a signal that is common to many environmental stresses. With respect to heat stress, application of ABA has been shown to induce the expression of two heat shock genes, pCE54 (7) and HSP70 (1 1).…”

“…ABA application enhances adaptation to various stresses such as recovery from heat shock, induction of freezing resistance in cell cultures, and acceleration of adaptation of cultured cells to salt stress (1,19). These results have led to the suggestion that ABA is a stress hormone and that it regulates stress responses common to many environmental stresses (2).…”

Levels of endogenous abscisic acid (ABA) in wild type were not required for the synthesis of heat shock proteins in detached leaves of tomato (Lycopersicon esculentum Mill., cv Ailsa Craig). Heat-induced alterations in gene expression were the same in the ABA-deficient mutant of tomato, flacca, and the wild type. Heat tolerance of the mutant was marginally less that the wild type, and in contrast, ABA applications significantly reduced the heat tolerance of wild-type leaves. It was concluded that elevated levels of endogenous ABA are not involved in the tomato heat shock response.ABA regulates many plant responses to the environment. Some of the functions of endogenous ABA have been demonstrated using mutants that are deficient in ABA. These mutants have impaired stomatal function (18), do not accumulate drought-induced gene products (3, 6), and do not develop cold hardiness (12) as a direct result of reduced ABA levels. Exogenous ABA treatments have been used to demonstrate the possible range of responses to the environment that ABA may control. ABA application enhances adaptation to various stresses such as recovery from heat shock, induction of freezing resistance in cell cultures, and acceleration of adaptation of cultured cells to salt stress (1,19). These results have led to the suggestion that ABA is a stress hormone and that it regulates stress responses common to many environmental stresses (2).The concentration of ABA increases in response to environmental stress. The greatest increase in ABA concentration has been observed in response to drought stress, yet other osmotic stresses such as salinity and PEG-mediated water deficit also result in elevated levels of ABA ( 19). Temperature also has an effect on endogenous ABA levels (8). However, the effect of a rapid increase in temperature or heat shock on leaf ABA concentration has not been widely studied (13).ABA applications mimic many changes in gene expression that occur during environmental stresses such as drought, salt, and cold stress. It has been demonstrated using an ABAdeficient mutant of tomato, flacca, during drought stress that 'This work was supported by

“…ABA accumulates in plant tissues in response to various stresses, suggesting that ABA has a role in adaptation (2,7,10,21,25). ABA accumulation, which has been shown to be heritable in some plants (22), has been found to be correlated with heritable stress tolerance (27).…”
