A reliable and efficient genetic transformation protocol for various turfgrass species and elite cultivars has been achieved using Agrobacterium tumefaciens. We describe a general protocol for the establishment of embryogenic cell cultures, Agrobacterium tumefaciens-mediated transformation, selection, and regeneration of transgenic turfgrass plants. Embryogenic callus is initiated from mature seeds, maintained by visual selection, and infected with an Agrobacterium tumefaciens strain (LBA4404) that contains either an herbicide-resistant bar gene or an antibiotic-resistant hyg gene driven either by a rice ubiquitin or CaMV35S promoter. Stable transformation efficiencies up to 43.3% were achieved. Southern blot and genetic analysis was used to confirm transgene integration in the turfgrass genomes and normal transmission and stable expression of the transgene in the T1 generation. We demonstrate herein that five elite cultivars of bentgrass can be genetically transformed using this single tissue culture media regime. Additionally, we report the successful Agrobacterium-mediated transformation of an elite tall fescue variety using minor variations in the same transformation protocol.
