| Abstract: | Fungal wheat (Triticum aestivum) diseases greatly affect crop productivity and require the economically and ecologically undesirable application of fungicides in wheat agriculture. We have generated transgenic wheat plants constitutively expressing an antifungal barley-seed class II chitinase. The transgene was stably expressed and the chitinase properly localized in the apoplast of the transgenic lines. The engineered wheat plants showed increased resistance to infection with the powdery mildew-causing fungus Erysiphe graminis. Received: 20 October 1998 / Accepted: 26 October 1998 |
