甘薯对干旱胁迫的生理响应及分子机理研究进展

摘要 甘薯作为一种较为耐旱的作物，在干旱胁迫下能够调节相关的生理生化反应来抵御干旱胁迫。综述了甘薯的光合系统、抗氧化系统、渗透调节系统以及一些重要的抗性基因在干旱胁迫下的响应，以期为提高甘薯产量、增加甘薯种植产业的经济效益提供参考。

Abstract As a drought-tolerant crop， sweet potato can regulate physiological and biochemical reactions to resist drought stress. This paper reviewed the photosynthetic system， antioxidant system， osmotic regulation system and the response of some important resistance genes to drought stress in sweet potato， in order to provide reference for improving the yield of sweet potato and increasing the economic benefits of sweet potato planting industry.
