文章简介水稻起源热带对冷十分敏感,所以其种植区域受到限定。随着人类的驯化选择,粳稻可以在较冷的区域种植,但是对这种适应性的分子机理知之甚少。本研究鉴定了粳稻中耐冷QTL基因COLD1。超表达粳稻基因COLD1~(jap)明显提高水稻的耐寒性,而降低表达或缺失该基因时水稻对寒害更加敏感。COLD1编码一
Article Introduction The origin of rice is very sensitive to cold, so its planting area is limited. With the domesticated selection of humans, japonica rice can be planted in colder areas, but little is known about the molecular mechanism of this adaptation. This study identified the cold tolerance QTL gene COLD1 in japonica rice. Overexpression of japonica rice COLD1 ~ (jap) significantly increased the cold tolerance of rice, while rice decreased its susceptibility to cold damage when it was expressed or deleted. COLD1 encoding one
