植物超氧化物歧化酶的研究进展

植物在生长发育的过程中会受到不同程度的生理或非生理胁迫，导致植物细胞内产生大量活性氧，影响植物正常生长代谢，甚至引起植物衰老死亡。大量研究显示，植物中的超氧化物歧化酶能发挥其独特的功能有效地清除多种活性氧，维持植物正常生命活动，并已经在农业、医疗、食品和化工多个领域得到了应用。就抗氧化酶系统中极其重要的成员———超氧化物歧化酶的分布类别、理化性质、生理功能及相关的研究应用情况进行了概述。

Research Progress on Plant Superoxide Dismutase

Plants are always suffered from physiological or non-physiological stress with different degrees in growth and development, which results in the production of numerous ROS affecting normal growth and metabolism of plants and even causing senescence and death. Numerous studies have shown that the superoxide dismutase of plants can exert its unique effect to remove a serious of ROS effectively so as to maintain plant′s ordinary life activities, and it has been widely applied in agriculture, medicine, food and chemical industry. We introduced the distribution, category, physical and chemical properties, physiological functions and progress on research and application of one of the most import members in antioxidant enzyme systems of plants-superoxide dismutase.
