A DNA for use in plant semi-dwarfing comprising: (a) a DNA coding for the transcription product of plant sd1 gene and complementary antisense RNA; (b) a DNA coding for an RNA with ribozyme activity for specific cleavage of the transcription product of plant sd1 gene; or (c) a DNA coding for an RNA preventing expression of the plant sd1 gene by an co-inhibitory effect. Independent claims are also included for: (1) a vector containing any of the DNAs; (2) a transformant plant cell sustaining expressibility of the DNA; (3) a transformant plant containing such transformant plant cells; (4) a propagative material of the transformant plant; (5) a method for producing the transformant plants by regenerating a plant body from the plant cells after transferring any of the DNAs into the plant cells; (6) a method for semi-dwarfing plants by inhibiting expression of the endogenous sd1 gene in cells of the plant body; and (7) a DNA encoding rice sd1 protein.
