使用 Northern 杂交分析研究了不同胁迫下水稻替代氧化酶基因（AOX1a 和 AOX1b）的转录水平。这些基因的稳态 mRNA 水平在低温、高盐和干旱条件下增加，但在外源 ABA 存在的情况下不会增加。在 AOX1a 的启动子区域也发现了两个 DRE/CRT 样序列。
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.
