Abstract
The invention relates to DNA constructs and methods for producing transgenic glyphosate tolerant, dwarf turfgrass plants that contain these constructs. The invention also relates to the maintenance of the transgenic turfgrass stand.
Claims20
A method for producing a low maintenance turfgrass plant comprising the steps of:
- a) contacting a recipient turfgrass plant cell with a transgene DNA construct comprising a herbicide tolerance gene and a heterologous dwarfing gene, wherein said DNA construct is incorporated into the genome of the recipient turfgrass plant cell;
- and b) regenerating the recipient plant cell into a turfgrass plant;
- wherein said turfgrass plant is herbicide tolerant and has a dwarf growth phenotype.
A method for controlling weeds in a turfgrass stand comprising:
- applying an effective amount of a glyphosate containing herbicide formulation to said turfgrass stand, wherein said turfgrass stand comprises a transgenic grass comprising a glyphosate tolerance transgene and a dwarfing transgene.
A method for inducing growth of a transgenic herbicide tolerant, dwarf turfgrass comprising:
- applying an effective amount a bioactive gibberellic acid containing formulation to said turfgrass seed, roots, or foliage.
A transgenic bluegrass plant comprising a transgene comprising a heterologous DNA molecule that provides herbicide tolerance and dwarf growth phenotype;
