| Abstract/Contents: | "The objectives of this study were to investigate infra- and interspecific gene flow of transgenic creeping bentgrass in the Willamette Valley, Oregon. Agrostis species are known for their propensity to hybridize freely. This study is critical to the understanding of gene flow in this crop--creeping bentgrass will be the first perennial, wind pollinated, outcrossing transgenic crop to be grown adjacent to naturalized and native populations of cross-compatible introduced and native species. Pollen movement was determined by placing transects of non-transgenic creeping bentgrass around a nursery of 286 transgenic plants. The plants were genetically engineered with the bar gene for tolerance to the herbicide glufosinate. The data were analyzed using an exponential decay model. Using this model, the following distances were predicted for transgenic pollen introgression to the 0.02% level. In 1998, along the SW transect, transgenic pollen traveled 3,500 ft and along the NE transect it traveled 4,296 ft. In 1999, the transgenic pollen was estimated to have traveled 1,022 ft to the SW, 1,892 ft to NE, 861 ft to the NW, and 1,022 ft to the SE. The crossing experiments resulted in the introgression of the bar gene from creeping bentgrass into A. canina, A. capillaris, A. castellana, A. gigantea, and A. pallens." |
