Also, this same method wherein the vir+ A. tumefaciens contains a vector comprising genetically-engineered T-DNA. There are further provided a transformed corn pollen grain, a corn pollen grain produced by a plant grown from a seedling infected with vir+ A. tumefaciens, a corn pollen grain produced by a plant grown from a seedling infected with vir° A. tumefaciens containing a vector comprising genetrically-engineered T-DNA, a corn pollen grain whose cells contain a segment of T-DNA, and corn derived from each of these pollen grains. There are also provided a transformed corn plant, a transformed corn plant derived from a corn seedling infected with vir+ Agrobacterium tumefaciens, a transformed corn plant derived from a corn seedling infected with vir+ A. tumefaciens containing a vector comprising genetically-engineered T-DNA, and a corn plant whose cells contain a segment of T-DNA. Finally, there are provided transformed corn derived from a corn seeding infected with vir+ Agrobacterium tumefaciens, and transformed corn derived from a corn seedling infected with vir+ A. tumefaciens containing a vector comprising genetically-engineered T-DNA.Other References
