Several papers have reported that, during germination, new LOXs are synthesized in the seedling and the cotyledons the LOX mRNAs synthesized during germination can also be found in the mature plant. Their levels were increased by the application of abscisic acid and jasmonic acid, or by stress such as wounding, pathogen infection, or water deficit (Porta and Rocha-Sosa 2002). 

D-glucopyranosyl esters of abscisic acid and /3-ionylideneacetic acid (120) have been prepared by treatment of the acid with a-acetobromoglucose in the presence of triethylamine/ Two papers " describe a new synthesis of y-ionone (64) in which the key intermediate (121) is prepared from y-cyclocitral (122) and acetone in the presence of BU2BSO3CH2CF3.

The Role of Abscisic Acid as a Stress Hormone. The role of ABA in water stress has been studied most extensively, although there is also evidence for involvement of ABA in other stresses such as salinity, mineral deficiency, high osmotic concentration, and water-logging. A review on the role of ABA in stress phenomena has appeared recently (18). 

Roles of Metabolites of Abscisic Acid. Nothing is known about the physiological role of PA and DPA in plants, although these two metabolites of ABA have been tested in several bioassays recently. In the cotton explant abscission assay PA had one-tenth of the activity of ABA (19). PA and DPA were equally effective in inhibiting a-amylase secretion by barley aleurone layers treated with glbberellin A3 DPA had approximately one-tenth of the activity of ABA in this system (74). The effect of PA on growth of bean embryos was negligible (75).
