Co-evolution of the host pathogen interaction between Leptosphaeria maculans and Brassica species

油菜是澳大利亚第三大出口作物，占世界菜籽油产量的13%。然而，由黄斑细球菌（Leptospheria maculans）引起的黑腿病导致年产量损失15%，100%的损失与抗性的破坏有关。国际投资为芸苔属和鹅毛甘蓝提供了新的基因组资源。利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。该研究还将为在其他物种上的应用提供一个模型和知识基础，从而产生具有更高植物保护和强大可靠生产力的增强型作物。

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.
