| Abstract/Contents: | "Tall fescue (Festuca arundinacea) is an important turf and forage grass species worldwide. Fungal diseases present a major limitation in its maintenance, especially in the southeastern United States. The two most severe fungal diseases are brown patch (BP), caused by Rhizoctonia solani, and gray leaf spot (GLS), caused by Magnaporthe grisea. In an attempt to develop tall fescue with resistance to these diseases, the following genes were introduced into 'Coronado' and 'Matador' tall fescue through Agrobacterium-mediated transformation: bacteriophage T4 lysozyme (T4), alfalfa beta-1,3 glucanase (AGLU1), a truncated frog dermaseptin SI gene (DSI), and the rice Pi9 gene. In replicated experiments under controlled environments, transformants expressing T4, AGLU1, or DSI exhibited increased resistance to both BP and GLS, whereas Pi9 only conferred resistance to GLS. Of 28 T0 transgenic plants evaluated, 12 exhibited a high level of resistance to GLS and 6 exhibited enhanced resistance to BP. Among the 28 transformants, 5 selections expressed enhanced resistance to both diseases." |
