Abstract: The plant-specific B3 superfamily constituted a large transcription factor superfamily. They play central roles in plant development, morphogenesis and stress-resistance. Taking total RNA of maize as template, REM gene was cloned by use the method of reverse transcription polymerase chain reaction (RT-PCR). Length of 1 047 bp cDNA sequence that encoding 349 amino acids was obtained. CD search result showed that it contained two B3-DNA domains and was named as ZmREM. Blast result indicated that ZmREM had 84% and 81% homology with Sorghum bicolor hypothetical protein and Setaria italica B3 domain-containing protein. In various tissues, gene expression in root was the highest. The expression of ZmREM in maize was induced by heat, high-salt, cold and PEG treatment. These results suggested that ZmREM might be a stress related gene of maize.

Key words: maize (Zea mays L.), REM transcription factor, gene cloning, abiotic stress
