Abstract:
A method for achieving the sufficient expression of a gene in a useful higher plant which has been transformed by transferring the above gene encoding a protein having a function carried by another organism so as to impart the function to the plant. Namely, a method for transforming a useful plant by transferring a gene of another species into the plant characterized in that the region of a factor relating to the poly(A) addition of the mRNA of the useful plant to be transformed contained in the base sequence of the gene of the other species is denatured into another base sequence not relating to the poly(A) addition of the mRNA without substantially altering the function of the protein encoded by the gene to be transferred; and a gene usable in the gene transfer.
