Patent ID: 7615685

Claim:
A method of producing human or animal food, comprising: a) obtaining a fertile transgenic Zea mays plant tolerant to an amount of glyphosate herbicide which would otherwise be toxic to an untransformed Zea mays plant, or a part of said fertile transgenic Zea mays plant, wherein the fertile transgenic Zea mays plant is prepared by a method comprising expressing in the genome of the fertile transgenic Zea mays plant a chromosomally integrated DNA, which encodes EPSP synthase operably linked to an actin promoter, wherein the chromosomally integrated DNA was introduced into the genome of said plant or a plant of a previous generation thereof by microprojectile bombardment, and wherein said DNA is expressed so that the transgenic plant exhibits tolerance to normally toxic levels of glyphosate rendering the plant identifiable over the corresponding untransformed Zea mays plant which does not comprise said DNA, and wherein the DNA is transmitted through a normal sexual cycle of the transgenic Zea mays plant to progeny; and b) producing human or animal food from the fertile transgenic Zea mays plant or part thereof.
