PROBLEM TO BE SOLVED: To provide an analytical method for an antagonistic activity against a cytokinin receptor, and further a method for quickly finding a substance having an antagonistic activity against the cytokinin receptor with a small amount of a sample by using the analytical method. SOLUTION: A specific cytokinin receptor. A DNA encoding the receptor. A method for analyzing antagonist activity against the cytokinin receptor. The analytical method comprises (1) the first process in which a test material and a substance having an agonistic activity against the cytokinin receptor come into contact with transformed cells which have been prepared by transducing a DNA encoding the cytokinin receptor, and (2) the second process in which, after the first process, the existence or the quantity of intracellular signal transmission from the cytokinin receptor expressed in the transformed cells is determined. |
