Title: Transformation of plant
Inventor: TADA YUICHI
IPC: C12N15/09
Filed: 1991-07-03
Abstract: PURPOSE:To produce a transformant plant not containing a heteroorganism- derived DNA. CONSTITUTION:Transformation of a plant is carried out by abundantly purifying only a plant-derived promoter, a structural gene and a terminator fragment and using the direct introduction method not requiring a vector, e.g. electroporation method or microprojection method. Since only amplified plant- derived genes are introduced in the resultant transformant plant, there is no danger of N production of a heteroorganism-derived unknown gene product. By this method, relaxation of the regulation as a recombinant is possible and image down as a gene-recombinant food can be remarkably prevented.
