Abstract excerpt
The Arabidopsis thaliana kas3 mutant was isolated based on the hypersensitivity of PSII to low temperature using a Chl fluorescence imaging technique. Chl content was lower in kas3 seedlings cultured at 23 degrees C than in the wild type, but PSII activity was only mildly affected. However, after the chilling treatment at 4 degrees C for 7 d, PSII activity was severely impaired in kas3. PSII was more sensitive to...
