A method of producing transformed Gramineae comprising making a wound in a seedling in an area of the seedling containing rapidly dividing cells and in ovulating the wound with vir+ Agrobacterium tumefaciens. Also, this same method wherein the vir+ A. tumefaciens contains a vector comprising genetically-engineered T-DNA. There are further provided a transformed pollen grain of a Gramineae, a pollen grain of a Gramineae produced by a plant grown from a seedling infected with vir+ A. tumefaciens, a pollen grain of a Gramineae produced by a plant grown from a seedling infected with vir+ A. tumefaciens containing a vector comprising genetically-engineered T-DNA, a pollen grain of a Gramineae whose cells contain a segment of T-DNA, and Gramineae derived from each of these pollen grains. There are also provided a transformed Gramineae plant, a transformed Gramineae plant derived from a seedling infected with vir+ Agrobacterium tumefaciens, a transformed Gramineae plant derived from a seedling infected with vir+ A. tumefaciens containing a vector comprising genetically-engineered T-DNA and a Gramineae plant whose cells contain a segment of T-DNA. Finally, there are provided transformed Gramineae derived from seedlings infected with vir+ Agrobacterium tumefaciens and transformed Gramineae derived from seedlings infected with vir+ A. tumefaciens containing a vector comprising genetically-engineered T-DNA.
