302 Insect resistant plant which is transgenic or mutant:
This subclass is indented under subclass 298. Subject matter wherein the higher plant, seedling, plant seed, or plant part is insect resistant and has been made via a transgenic method or a mutation step. (1) Note. Transgenic means that new genetic information has become embedded into the germ line of the plant. A mutant plant is one wherein a change in the structure of the genetic material (i.e., the DNA base sequence) of the plant has occurred. Mutations result in heritable alterations in the genotype of the plant.
