    • The present invention relates to a recombinant expression vector for production of multiple stress tolerant plants, which is prepared by attaching multiple stress tolerant genes to oxidative stress inducible promoter, multiple stress tolerant plants transformed with the expression vector and a preparation method for the plants, more precisely, a recombinant expression vector for production of multiple stress tolerant plants that is prepared by combining oxidative stress inducible peroxidase promoter (SWPA2) originated from sweetpotato with multiple stress tolerant genes (SOD (superoxide dismutase) and APX (ascobate peroxidase)) to express the multiple stress tolerant genes in chloroplasts, multiple stress tolerant plants transformed with the expression vector above and a preparation method for the plants. The recombinant expression vector of the present invention is very useful for the production of transformed plants having very strong resistance against multiple stresses caused by oxidative stress inducible herbicides, cold injury, high temperature, salt damage, or various environmental pollutions generating active oxygen, so that the vector can be a great contribution to the increase of productivity of agricultural crops or mass-production of useful components.
    • 本发明涉及用于产生多种胁迫耐受植物的重组表达载体,其通过将多个胁迫耐受基因连接到氧化应激诱导型启动子,用表达载体转化的多种胁迫耐受植物和植物的制备方法 准确地说,通过将源自甘薯的氧化应激诱导型过氧化物酶启动子(SWPA2)与多重胁迫耐受基因(SOD(超氧化物歧化酶)和APX(ascobate过氧化物酶))组合来制备多重胁迫耐受植物的重组表达载体,以表达 叶绿体中的多重胁迫耐受基因,用上述表达载体转化的多种胁迫耐受植物和植物的制备方法。 本发明的重组表达载体对于生产对由氧化应激诱导型除草剂,冷伤害,高温,盐损害或产生活性氧的各种环境污染引起的多重胁迫具有非常强的抗性的转化植物的生产非常有用,使得 该载体可以为提高农作物生产力或大量生产有用成分做出重大贡献。
