项目摘要

Plants like Brassica napus (canola) are under constant threat from pests and pathogens. One of the most devastating fungal pathogens affecting this important crop for Canada is Sclerotinia sclerotiorum (white mold) the causal agent of stem rot. I am investigating how canola responds to fungal pathogens because a) canola is a major source of food and fuel; b) canola does not have true genetic immunity to S. sclerotiorum and; c) new canola genome resources can be used to gain insights into the regulatory processes required for plant defense and more specifically improved crop health for primary and applied research. The long-term objective of my research program is to 1) understand the genetic and molecular systems underpinning plant microbe interactions in the canola - Sclerotinia pathosystem 2) identify the genes responsible to host plant immunity and 3) implement and integrate this fundamental knowledge in the development of new plant protection methods. We can begin to address these challanges through these specific short-term objectives: i) to understand how the host plant perceives S. sclerotiorum at the cell interface and how these interactions result in plant protection or susceptibility; ii) to functionally characterize immunity genes to improve crop protection and iii) determine whether cellular features of the plant stem are responsible for slowing the infection process. This combined approach will allow for a comprehensive understanding of how the plant detects and stimulates cellular immunity networks responsible for protection and the limiting of disease progression. The molecular data will be complemented with in depth histological analysis of susceptible and tolerant varieties that show differences in disease severity. This hypothesis driven research will identify genes and global phosphorylation targets responsible for this host-pathogen interaction. Collectively, this NSERC Discovery Grant will promote the training of one Postdoctoral Fellow, two PhD students, one MSc student and undergraduate researchers in the lab. Together, we will examine the functional role of immunity networks responsible for crop protection in the economically and agriculturally important oilseed, canola. The results of this seminal research will contribute to the understanding of host pathogen interactions for those interested in crop improvement and facilitate technology transfer.
像甘蓝型油菜(油菜)这样的植物不断受到害虫和病原体的威胁。影响加拿大这种重要作物的最具破坏性的真菌病原体之一是核盘菌(白色霉菌),它是茎腐病的病原体。我正在研究油菜对真菌病原体的反应,因为a)油菜是食物和燃料的主要来源; B)油菜对S.核盘菌和; c)新的卡诺拉基因组资源可用于深入了解植物防御所需的调控过程,更具体地说,可用于初级和应用研究以改善作物健康。我的研究计划的长期目标是1)了解在油菜-核盘菌病理系统中支持植物微生物相互作用的遗传和分子系统2)确定负责宿主植物免疫的基因和3)在新的植物保护方法的开发中实施和整合这些基础知识。我们可以开始通过这些具体的短期目标来解决这些挑战:i)了解宿主植物如何感知S。本发明的目的在于:i)确定在细胞界面处的核盘菌的相互作用以及这些相互作用如何导致植物保护或易感性; ii)功能性地表征免疫基因以改善作物保护和iii)确定植物茎的细胞特征是否负责减缓感染过程。这种结合的方法将允许全面了解植物如何检测和刺激负责保护和限制疾病进展的细胞免疫网络。分子数据将与显示疾病严重程度差异的易感和耐受品种的深入组织学分析相补充。这种假设驱动的研究将确定基因和全球磷酸化的目标,负责这种宿主-病原体相互作用。总的来说,这个NSERC发现补助金将促进一个博士后研究员,两个博士生,一个硕士生和实验室的本科研究人员的培训。我们将共同研究负责作物保护的免疫网络在经济和农业上重要的油菜籽中的功能作用。这项开创性研究的结果将有助于那些对作物改良感兴趣的人了解宿主病原体的相互作用,并促进技术转让。
