Disclosed are: a substance which has an activity of inhibiting the intracellular signaling from a plant-derived cytokinin receptor and which can control the growth or differentiation of a plant. Also, disclose is a method for searching for a chemical substance capable of promoting the growth of a root of a plant, which comprises measuring the level of intracellular signaling from the receptor in a system where a cell having the receptor is contacted with a chemical substance having an agonistic activity on the receptor and a substance to be tested, comparing the level of intracellular signaling measured in the preceding step with a level of intracellular signaling measured in the absence of the chemical substance, and determining the chemical substance as being a chemical substance capable of promoting the growth of a root of a plant based on the difference obtained by the comparison; and others.
本发明涉及一种具有抑制植物来源细胞因子受体内部信号传递活性的物质,可控制植物的生长或分化。同时,还揭示了一种搜寻促进植物根生长的化学物质的方法,其中包括测量具有激动剂活性的化学物质与待测试物质接触的受体细胞系统中的细胞内信号传递水平,将前一步骤中测量的细胞内信号传递水平与无化学物质存在时测量的细胞内信号传递水平进行比较,并根据所得到的差异确定该化学物质为能够促进植物根生长的化学物质。
