Method of controlling character of monocotyledon by modification and/or overexpression of cytochrome P450 monooxygenase gene involved in brassinosteroid biosynthesis and monocotyledon modified by the gene

摘要

A method of producing a modified monocotyledonous plant having a desired character is provided. The method comprises isolating a gene containing a nucleic acid hybridizable to a nucleic acid indicated by SEQ ID NO. 1 under stringent conditions, and inhibiting expression of the isolated gene.
