Transgenic Tall Fescue Plants Overezpressing 2-Cystein Peroziredozins Confers Enhanced Tolerance Against Ozidative and High Temperature Stress
1. Introduction Oxidative stress caused by reactive oxygen species (ROS) is one of the major factors causing injury to plants exposed to environmental stress. The ROS generated by oxidative stress can cause serious damage to biological macromolecules such as protein, lipid, and nucleic acid and eventually lead to cell death. The ubiquitously distributed peroxiredoxin have been shown to have diverse functions in cellular defense-signaling pathways. In particular, plant 2cysteine peroxiredoxins (2-Cys Prx) important roles in cellular responses to pathogens and external stresses. In order to understand its high adaptability to harsh environmental conditions on the basis of molecular biology and to develop its transgenic plants with enhanced tolerance to environmental stress, Arabidopsis 2-Cys Prx gene was introduced into tall fescue (Festuca arundinacea schreb.), a forage crop.
