Research Progress on GPX in Plants

doi:10.13560/j.cnki.biotech.bull.1985.2016.09.002

Abstract

Abstract: Adverse stress induces plants to produce excessive reactive oxygen species（ROS）,which can cause oxidative stress,and seriously affect their growth and development. Accordingly,plants produce a variety of antioxidants and antioxidant enzymes adjusting redox balance in order to adapt to many adverse environments. Glutathione peroxidase（GPX）is one of the most important antioxidant enzymes in plant. In this paper,recent research progresses on structure characteristics,subcellular localization,substrate specificity and functions of GPX are mainly reviewed,and finally the future research directions are prospected.

Key words: glutathione peroxidase（GPX）, thioredoxin, stress tolerance
