 note = {To determine how enhancement of a scavenging system of reactive oxygen species is involved in the mitigation or delay of the occurrence of chilling injury, transgenic rice plants that constitutively overexpress wheat catalase were investigated. After chilling treatment (5℃) for up to 8 days, the transgenic rice exhibited less injury than did the wild type. Furthermore, the transgenic rice recovered better from chilling stress than the wild type when they were returned to non-chilling temperatures after the chilling treatment for 2 to 4 days. The advantages of the transgenic rice in chilling tolerance were consistent with the results that, under the chilling process or the rewarming process after the chilling treatment, there were less amount of hydrogen peroxide, less extent of plasma membrane-associated injury, and less amount of lipid peroxides in the transgenic rice than in the wild type. These suggest that the introduction of catalase into rice plants results in increased chilling tolerance as a consequence of increased membrane stability due to effective removal of reactive oxygen species by high activity of catalase transformed.},
