Molecular basis of abiotic stress tolerance of plants

葡萄藤具有世界经济意义，因为它在世界各国都被用于葡萄种植，包括加拿大。在加拿大冬季气温低于零下20摄氏度的情况下，冰冻的温度可能不利于植物的生存。品种，包括加拿大水果和葡萄酒行业使用的品种，在严冬会受到影响，甚至死亡，对该行业造成重大经济影响。事实上，缺乏足够的耐寒性是加拿大精英酿酒葡萄生产的最大威胁。有趣的是，许多本土物种在经历了一段时间的低温非冰冻后存活了下来。因此，了解本土物种如何获得耐寒能力是很重要的。

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.
