| Abstract/Contents: | "Disease resistance to fungal pathogens is a highly desirable trait in both crop and ornamental plants. In the case of Paspalum vaginatum (seashore paspalum) a warm-season turf grass species that is ideal for golf and sports fields, dollar spot is the most destructive and costly disease to manage. Dollar spot is caused by Clarireedia homoeocarpa, a non-sporulating fungal pathogen that damages turfgrasses by exuding oxalic acid and colonizing the damaged tissue. Our objective is to develop seashore paspalum with dollar-spot resistance by using a gene for oxalate-oxidase to neutralize the oxalic acid. Towards that end, a wheat germin gene, gf 2.8, will be incorporated via biolistic transformation. Two promoters, CaMV35S and ZmUb, will be evaluated for their ability to drive gf 2.8 with the rice catalase terminator. Negative and positive selection efficiency will be compared using hygromycin B and arabitol. Six week old embryogenic callus obtained from nodal explants will be used for biolistic transformation. Disease resistance will then be quantified through field trials and oxidase assays." |
