Molecular basis of abiotic stress tolerance of plants

葡萄藤在世界范围内具有重要的经济意义，因为它被用于世界各国的葡萄栽培，包括加拿大。在冬季气温低于零下20摄氏度的加拿大，冰冻的温度对植物的生存是有害的。品种，包括加拿大水果和葡萄酒行业使用的品种，在严冬受到影响甚至死亡，对该行业造成重大的经济影响。事实上，缺乏足够的耐寒性是加拿大优质酿酒葡萄Vitis vinifera生产的最大威胁。有趣的是，许多本地物种在经历了一段时间的低温后存活了下来。因此，了解本地物种如何实现抗冻性是很重要的。

Grapevine has worldwide economic significance because it is used for viticulture in countries around the world, including Canada. Freezing temperatures can be detrimental for a plant's survival in Canada with winter temperatures below -20C. Cultivars, including those used in the Canadian fruit and wine Industry, are affected and even killed in severe winters, resulting in a substantial economic impact to the Industry. Indeed, lack of sufficient winterhardiness is the greatest threat to the production of the elite winegrape Vitis vinifera in Canada. Interestingly, many native species survive after being subjected to a period of low, non-freezing temperatures. Understanding how native species achieve freezing tolerance is thus important.
