摘要

榖胱甘肽、榖胱甘肽還原酵素、榖胱甘肽S-轉移酵素與榖胱甘肽過氧化酵素為活化氧族清除系統之成員。本文係綜合討論榖胱甘肽及其相關酵素在水稻環境逆境下所扮演之角色。證據顯示榖胱甘肽可調控水稻在低溫、鹽分、過量銅與鎘及除草劑處理之抗性。

Glutathione (GSH), glutathione reductase (GR), glutathione S-transferase (GST), and glutathione peroxidase (GPX) are important components of scavenging system for reactive oxygen species in plants. The importance of glutathione and its related enzymes in rice plants in response to abiotic stresses is reviewed. Evidence is provided to show that GSH plays critical role in tolerance to chilling, salinity, copper and cadmium excess, and herbicide treatment.
