Affinity constants of various cytokinin bases for AHK3 and ZmHK1 receptors in different assay systems. The affinity constants were measured in a plant (tobacco microsomes) or bacterial (E. coli spheroplasts) assay system as indicated. The ordinate (log scale) shows the apparent K A=K D –1 which positively correlates with the ligand affinity of the receptor. tZ, trans-zeatin; cZ, cis-zeatin; iP, isopentenyladenine; BA, N 6-benzyladenine; DZ, dihydrozeatin; TD, thidiazuron; Ade, adenine.
