Abstract/Contents: | "The use of buffalograss as a low maintenance turfgrass has increased in the past decade because of its excellent drought tolerance and improved turf quality. One of the challenges of growing buffalograss, however, is its slow growth rate which may cause weed infestation during establishment. Developing buffalograss with Roundup® tolerance may provide an effective strategy to control grassy weeds, many of which respond to herbicides similarly as buffalograss. Here we report the establishment of a transformation protocol using particle bombardment for transferring the 5-enolpyruvylshikimate phosphate synthase gene (cp4 epsps) into embryogenic callus and subsequently recovering transgenic plants for a turf-type vegetative buffalograss cultivar '91-118'. Southern blot and Trait RUR Lateral Flow Test confirmed the successful integration of the cp4 epsps gene into the buffalograss genome and the production of the CP4 EPSPS enzyme in transgenic buffalograss plants. A delay for selection increased callus transformation efficiency. A delay of either 7 or 28 days for selection yielded 1.7 ± 0.5% and 2.0 ± 0.3% of glyphosate resistant calluses, respectively while a delay of 3 days yielded only 0.4 ± 0.4% of glyphosate resistant callus. The selection level also had an effect on the transformation efficiency; selection medium containing 1 mM glyphosate yielded an average of 8.0 ± 3.1% of glyphosate resistant calluses, while the selection medium containing 2 mM glyphosate resulted in an average of 2.5 ± 0.8% resistant calluses" |
