Each year Canada loses hundreds of millions of dollars from loss in crop productivity caused by different environmental stresses. Oxidative stress is a common response to different stresses such as heat, cold, high-light, drought, osmotic shock, wounding, UV-B radiation, ozone, aluminum and pathogens. Our studies on aluminum stress and tolerance allowed us to identify several genes that could play an important role in regulating plant responses to oxidative stress. Improving tolerance to this stress will likely enhance plant fitness by increasing cross-tolerance to a variety of stresses. To achieve this goal, we will:

加拿大每年因不同的环境压力导致的作物产量下降而损失数亿美元。氧化应激是对热、冷、强光、干旱、渗透休克、损伤、UV-B辐射、臭氧、铝和病原体等不同应激的一种常见反应。我们对铝胁迫和耐受性的研究使我们确定了几个可能在调节植物对氧化胁迫的反应中起重要作用的基因。提高对这种胁迫的耐受性可能会通过增加对各种胁迫的交叉耐受性来提高植物的适应性。为实现这一目标，我们将：
