H2O2参与大豆根尖铝毒调节的研究
Hydrogen Peroxide Involved in Regulation Aluminum Toxicity in Root Tips of Soybean
摘要
Abstract
The alleviating effect of exogenous H2O2 on aluminum (Al) toxicity and its possible mechanisms of physiological and biochemical regulation were studied in soybean. Pretreatment with O. 1 mmol · L-1 H2O2 during soybean exposure to Al significantly reduced aluminum content, active oxygen species accumulation and membrane permeability in the root tip. Pretreatment with H2O2 also increased the protective enzyme activity of SOD and CAT. Moreover, the alleviating effect was reversed by the addition of H2O2 scavenger CAT. These findings indicated that H2O2 act as a signal molecule involved in the protection of plants against A1 toxicity by enhancing protective enzyme aetivity.关键词
