|a Rice (Oryza sativa L.) seedlings, when kept at 42 degrees C for 24 h before being kept at 5 degrees C for 7 d, did not develop chilling injury. Chilling resistance was enhanced in parallel with the period of heat-treatment. The level of APX activity was higher in heated seedlings whereas CAT activity was decreased by heat stress. There was no significant difference in SOD activity between heated and unheated seedlings. The elevated activity of APX was sustained after 7 d of chilling. The cytosolic APX gene expression in response to high and low temperature was analysed with an APXa gene probe. APXa mRNA levels increased within 1 h after seedlings were exposed to 42 degrees C. Elevated APXa mRNA levels could also be detected after 24 h of heating. The APXa mRNA level in preheated seedlings was still higher than unheated seedlings under cold stress. The promoter of the APXa gene was cloned from rice genomic DNA by TAIL-PCR, and characterized by DNA sequencing. The promoter had a minimal heat shock factor-binding motif, 5'-nGAAnnTTCn-3', located in the 81 bp upstream of the TATA box. Heat shock induction of the APXa gene could be a possible cause of reduced chilling injury in rice seedlings
