Crown Rust Resistance in Transgenic Italian Ryegrass (L. Multiflorum) Expressing a Rice Chitinase Gene and Crosses with Cytoplasmic Male Sterile Hybrid Ryegrass

Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grasses in the temperate region. In ryegrasses, crown rust (Puccinia coronata) is the most serious foliar fungal disease and brings about a reduction of herbage yield and loss of palatability to grass-eating domestic animals. In this study, we tried to increase tolerance to the pathogen by introducing a rice chitinase gene using particle bombardment.
