Transcript levels of alternative oxidase genes (AOX1a and AOX1b) of rice were studied under various stresses using a Northern hybridization analysis. The steady-state mRNA levels of these genes increased under low temperature, high salt and drought conditions, but not in the presence of exogenous ABA. Two DRE/CRT-like sequences are also found in the promoter region of AOX1a.
