There are two types of receptor, termed fast and slow sites [21]. The fast responses (detectable in <5 min) appear to be brought about by membrane-mediated phenomena, while the slow responses, which involve protein synthesis, are not detectable within the first half hour. The receptor types have different molecular requirements, and the fast reaction is not a pre-requisite for the slow. Growth assays employed to assess activity include Avena coleoptile, lettuce hypocotyl, rice seedling, and bean axis. Other types include lettuce seed and wheat embryo germination, transpiration assays, leaf disk senescence, and more recently, a-amylase production. Stomatal closing using epidermal strips is an assay for the fast receptor.

Fig. 7.1. (A) Time course of a-amylase release by 10 aleurone layers of Himalaya barley incubated with 1 iM GA. Enzyme activity measured in the medium surrounding the aleurone layers and in the supernatant of a 0.2 M NaCl extract of the aleurone layers. Total refers to the sum of these two activities. After Chrispeels and Varner, 1967 [22]. (B) Midcourse inhibition of a-amylase production and release by abscisic acid and cycloheximide. Aleurone layers were incubated in 0.1 pM GA for 11 h and then 5 pM abscisic acid or lOpg/ml cycloheximide was added (arrowed). After Chrisppels and Varner, 1967 [23]...
