【摘要】 干旱、盐碱和低温等逆境是严重影响栽培植物生产的非生物胁迫因素。导入外源目的基因已发展成为改良作物对逆境胁迫耐性的新途径。现今已应用于植物胁迫耐性改良的基因包括编码活性氧清除酶类、膜修饰酶类、胁迫诱导蛋白和渗调物质合成酶等基因更多还原

【Abstract】 Plant productivity is greatly influenced by abiotic stresses, such as drought, salinity and low temperature etc. Introduced foreign target genes has been a new way to improve the stress tolerance in crops. Up to date, the transgenes used in improving stress tolerance in plants include the genes encoding superoxide scavenging enzymes, membrane modifying enzymes, stress induced protein and osmolyte producing enzymes.更多还原
