Stagonospora nodorum is a fungus that causes leaf and glume blotch disease on wheat. This disease alone causes $55 million dollars in yield losses per annum. Traditional breeding methods have yielded crops that are only mildly resistant leaving control of the disease to be worryingly reliant on fungicides. This project aims to identify and characterise proteins that the fungus secretes to cause disease on wheat. By identifying these proteins, it is anticipated that strategies, both traditional and modern, could be employed to enable better control of the disease. This in turn would help provide a long term and secure supply of wheat and wheat based products to the community.

棒状Stagonospora nodorum是一种引起小麦叶片和颖片斑点病的真菌。仅这种疾病每年就造成5500万美元的产量损失。传统的育种方法产生的作物只有轻微的抗性，令人担忧的是，这种疾病的控制依赖于杀菌剂。该项目旨在鉴定和表征真菌分泌的导致小麦疾病的蛋白质。通过鉴定这些蛋白质，预计可以采用传统和现代的策略来更好地控制这种疾病。这反过来将有助于向社区提供长期和安全的小麦和小麦产品供应。
