| Abstract: | Adopting modern genetic engineering to improve turfgrass has enormous commercial potential. Turfgrass tissue culture and a regeneration system have been developed for direct DNA transfer and Agrobacterium mediated transformation. Genetically modifying turfgrass would improve its drought resistance, heat and cold tolerance, disease resistance, herbicide resistance, and trampling tolerance. Transgenic turfgrass carrying the isopentenyl transferase gene showed enhanced tillering ability and extended green period under severe winter conditions. At the same time as looking to expected benefits, biological safety issues with transgenic turf should also be evaluated. |
