Brassica canola is Australia's third largest export crop, producing 13% of the world's canola oil. However, blackleg disease, caused by the fungus Leptospheria maculans leads to annual yield losses of 15%, with 100% loss associated with breakdown of resistance. International investment has provided novel genome resources for Brassica and L. maculans. Applying these resources to understand the co-evolution of this plant-fungal interaction could prevent the current boom-bust cycle of canola production in Australia. This study will also provide a model and knowledge base for applications in other species, leading to enhanced crops with increased plant protection and robust, reliable productivity.

油菜籽是澳大利亚第三大出口作物，生产世界油菜籽油的13%。然而，黑胫病，由真菌Leptospheria maculans引起的导致年产量损失15%，与100%的损失与抗性的崩溃。国际投资为芸苔属和L.斑点。应用这些资源来了解这种植物-真菌相互作用的共同进化，可以防止目前澳大利亚油菜生产的繁荣-萧条周期。这项研究还将为其他物种的应用提供一个模型和知识基础，从而提高作物的植物保护和强大，可靠的生产力。
