Abstract
For the purpose of providing a technique available for the production of a transgenic plant, a method to promote the proliferation of a plant cell is developed. This invention provides an amino acid sequence of precursor polypeptide of phytosulfokine (preprophytosulfokine), a growth factor of plant origin, and a base sequence encoding the phytosulfokine precursor polypeptide. Incorporation of the gene encoding the phytosulfokine precursor polypeptide enables the promotion of plant cell proliferation.
