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.
公开了一种物质,该物质具有抑制来自植物的细胞分裂素受体的细胞内信号传导的活性,并能控制植物的生长或分化。此外,还公开了一种寻找能够促进植物根部生长的化学物质的方法,该方法包括在一个系统中测量来自受体的细胞内信号水平,在该系统中,具有受体的细胞与对受体具有激动活性的化学物质和待测物质接触、将前一步骤中测得的细胞内信号水平与没有该化学物质时测得的细胞内信号水平进行比较,并根据比较得出的差异确定该化学物质是能够促进植物根部生长的化学物质;及其他。
