Claims
- 1. A transgenic plant cell containing a DNA molecule, the sequence of which is obtained from Streptococcus mutans and encodes a glucosyltransferase C enzyme, wherein the plant cell is derived from a plant selected from the group consisting of maize, potato, cassava, sweet potato and sugar cane.
- 2. The plant cell of claim 1 which is transformed by Agrobacterium tumefaciens, electroporation, retroviruses, bombardment or microinjection.
- 3. The plant cell of claim 1 wherein the enzyme produces a glucan in the amyloplast or vacuole of the plant cell.
- 4. The plant cell of claim 3 wherein the enzyme produces a glucan in the amyloplast of maize cells.
- 5. A transgenic plant regenerated from the plant cell of claim 1.
- 6. The plant of claim 5 wherein the plant is a maize line deficient in starch biosynthesis.
- 7. The plant of claim 6 wherein the plant is maize of genotype sh.sub.2, bt.sub.2 or bt.sub.1.
- 8. A transgenic plant seed containing a DNA molecule, the sequence of which is obtained from Streptococcus mutans and encodes a glucosyltransferase C enzyme, wherein the plant seed is derived from a plant selected from the group consisting of maize, rye, barley, sugarcane, wheat, sorghum, oats, millet, triticale and rice.
- 9. The plant seed of claim 8 wherein the DNA molecule contains a promoter selected from the group consisting of 22 kDa zein, opaque2, gamma zein and waxy gene promoters.
