Through this proposal we aim to identify molecular mechanisms behind drought tolerance and generate superior canola varieties that are tolerant to extreme weather conditions that inflict significant losses in revenue on an annual basis. Canola is the major cash crop in Canada and contributes ~19.3 billion dollars to the Canadian economy. In recent years, due to extreme changes in weather patterns observed due to global warming, canola crop is constantly exposed to severe drought conditions that result in more than 20-30% loss in revenue. In addition to this, early and late season extreme frost conditions also affect seedling establishment and proper seed set respectively. Thus, engineering novel canola traits that allow resilience to unpredictable temperature fluctuations is imperative to sustain canola yield under changing climatic conditions. We have recently uncovered that reducing endogenous levels of a steroid plant hormone results in increased drought tolerance in the model plant Arabidopsis (close relative of canola). We propose to use both GM and non-GM approaches to generate canola plants that are resilient to weather conditions that were seldom encountered under optimal growing conditions in Canada. In the long-term, this technology will be combined with the frost-tolerant canola platform that is already in progress in the lab to create novel canola varieties. This proposal is directly aligned with the 'Environment and Agriculture' target area under the strategic research topic 'Biotechnology/generation of climate-change-resilient plants'. Our supporting organization Siniazo Biotech Inc. owns exclusive licensed rights to the suite of proprietary molecular genetic technologies that confer drought tolerance in model crops that is currently unparalleled in the industry. Siniazo Biotech will be actively involved in development of the proposal, research goals and continue to provide regular guidance during the project to generate canola varieties with climate-resilient traits that can be commercialized. Achieving the objectives of this project will result in development of a new climate-resilient canola traits that will allow sustained yield under challenging conditions and provide great economic and socio-economic benefits to Canadian producers.

通过这项提案，我们旨在确定耐旱性背后的分子机制，并产生宽敞的低芥酸菜籽品种，这些品种对极端天气条件的耐受性，每年都会造成重大收入损失。低芥酸菜籽是加拿大的主要经济作物，为加拿大经济贡献了约193亿美元。近年来，由于全球变暖引起的天气模式的极大变化，低芥酸菜籽作物不断暴露于严重的干旱状况，导致收入损失超过20-30％。除此之外，早期和后期的极端霜冻条件还分别影响幼苗的建立和适当的种子设定。因此，工程新型的低油菜还能使弹性在不可预测的温度波动上恢复活力对于在不断变化的气候条件下维持低芥酸菜籽的产量至关重要。我们最近发现，降低类固醇植物激素的内源性水平会导致模型植物拟南芥（菜籽的亲戚）的干旱耐受性提高。我们建议同时使用GM和非GM方法来产生对天气条件有抵抗力的低芥酸菜籽植物，这些天气条件在加拿大最佳生长条件下很少遇到。从长远来看，这项技术将与耐霜的低芥酸菜籽平台相结合，该平台已经在实验室中正在进行中，以创建新型的低芥酸菜籽品种。该提案与战略研究主题“生物技术/气候变化富裕植物的生成”下的“环境和农业”目标领域直接保持一致。我们的支持组织Siniazo Biotech Inc.拥有专有分子遗传技术套件的独家许可权，这些权利赋予了该行业中目前无与伦比的模型作物中赋予干旱耐受性。 Siniazo Biotech将积极参与提案的制定，研究目标，并在项目期间继续提供定期指导，以产生具有气候富特性的低芥酸菜籽品种，这些特征可以商业化。实现该项目的目标将导致发展新的气候富菜籽特征，该特征将在具有挑战性的条件下允许持续的产量，并为加拿大生产者提供巨大的经济和社会经济利益。
