PROBLEM TO BE SOLVED: To provide a new synthesis inhibitor for auxin being a plant hormone.SOLUTION: YUCCA specific IAA synthesis inhibitor having a methimazole-like five-membered ring structure expressed by formula I, which inhibits the activity of YUCCA being flavin monooxygenase in an auxin biosynthetic pathway of a plant (in the formula, X expresses a carbon atom or a nitrogen atom, Y expresses a carbon atom, the bond between X and Y is a single bond or a double bond, and when the bond between the nitrogen atom to which Y and Rare bonded and Y is a single bond, Rexpresses a hydrogen bond, and when the bond between the nitrogen atom to which Y and Rare bonded and Y is a double bond, Ris absent). |
