Molecular basis of abiotic stress tolerance of plants

葡萄藤具有世界性的经济意义，因为它被用于世界各国的葡萄栽培，包括加拿大。在加拿大，冬季气温低于零下20摄氏度，冰冻温度对植物的生存不利。包括加拿大水果和葡萄酒行业使用的品种在内的品种在严冬中受到影响，甚至死亡，对该行业造成重大经济影响。事实上，缺乏足够的抗寒性是最大的威胁，生产的精英酿酒葡萄葡萄属葡萄在加拿大。有趣的是，许多本地物种在经历了一段时间的低温，非冻结温度后幸存下来。因此，了解本地物种如何获得抗冻性非常重要。

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.
