ABSTRACT:
The present invention discloses plant cells which contain modified 7S legume seed storage protein. Modification of 7S seed storage proteins which are expressible in plant cells and transformation of such genes into plant cells is also taught. Furthermore, methods and DNA molecules useful for producing plant cells containing modified 7S seed storage proteins are also disclosed. The invention is exemplified by insertion of an oligonucleotide encoding 15 amino acid residues, including 6 methionines, into a Phaseolus vulgaris phaseolin gene, thereby tripling its content of sulfur-containing amino acids.
