Description	We developed transgenic rice plants (Oryza sativa L. cv. Daeribbyeo) overproducing cytosolic glutathione reductase (GR) using a GR gene from Brassica campestris and studied their response to photo-oxidative stress in the presence of methyl viologen (MV, 10 and 50 microM concentrations) under room (25 °C) and moderately elevated temperature (35 °C) by analysis of chlorophyll a fluorescence parameters (FV/FM, qN and qP) and of chlorophyll content. The results show that elevated temperature enhances and accelerates the photo-oxidative damage to photosynthetic apparatus expressed mainly by a fast decrease of qN. Higher temperature was shown to support the protective reaction in transformed rice plants for lower MV concentration (10 microM) and eliminated the enhanced tolerance of photosystem II photochemistry to photooxidative stress for the case of higher (50 microM) MV concentration. The results are explained by different mechanisms and temperature dependences of oxidative and protective reactions. We developed transgenic rice plants (Oryza sativa L. cv.
