| Abstract/Contents: | Discusses the history, application and the advancements of transgenic turfgrasses. Addresses the potential benefits of using DNA technology in order "to introduce other traits, such as insect resistance, disease resistance, and improved environmental stress tolerance." Details the differences beteween crop biotechnology and turf biotechnology. Comments on the decreased herbicide use that comes from transgenic turf. Details the potential risks that this new technology could bring, like the new transformed plants becoming weeds along with the possbile cross-pollination of the new transformed plants to relatives. Also discusses the potential development of resistant weed populations. Mentions the "research in developing transformation systems, gene constructs, promoter development, etc, to decrease the chance of gene transfer via sexual reproduction, seed, or pollen." Lists the "several factors [that] must be considered in each turfgrass species for potential gene transfer: 1)the proximity and number of potentially weedy relatives that can act as a maternal parent; 2)sexual compatibility of these relatives; 3)the fertility of offspring of such crosses; 4)selection pressures that act on the hybrid progeny; 5)fitness of hybrids under agricultural and turfgrass situations." Illustrates specific cases for turfgrass species: Kentucky bluegrass, creeping bentgrass, St. Augustinegrass, and Bermudagrass. Cites that "transforming, testing, and releasing an herbicide-resistant plant is a costly venture"; however, suggests that "herbicide-resistant turfgrasses will be released on the market first because the genes are already available and have been used in other crops." Addresses the negative consumer perception regarding biotechnology. Suggests that "man of the question raised cannot be answered" and that "additional research on the ecological effects of the transgenes in turfgrass communities and larger-scale release with careful monitoring is needed to fully understand the ecological and safety concerns." |
