<P>PROBLEM TO BE SOLVED: To provide a method for promoting bifurcation formation of a plant, dwarfing and sterility the same, and multiple flower bud formation and to provide a chemical for promoting the bifurcation formation of the plant and/or for promoting dwarfing and/or sterilizing and/or the multiple flower bud formation. ??<P>SOLUTION: Phytoplasma is a pathogenic microbe which causes bifurcation formation promotion of the plant and/or the dwarfing and/or the sterility and/or the multiple flower bud formation. The bifurcation formation promotion of the plant and/or the dwarfing and/or the sterility and/or the multiple flower bud formation are promoted by introducing a PAM 765 peptide of the Phytoplasma into a plant individual. The chemical contains the PAM 765 peptide or a gene to encode the PAM 765 peptide and promotes the bifurcation formation of the plant and/or the dwarfing and/or the sterility and/or the multiple flower bud formation. ??<P>COPYRIGHT: (C)2010,JPO&INPIT ??
