摘　　要：[目的]对新春6号小麦的抗旱DREB基因进行表达特征分析。[方法]在干旱逆境胁迫下,考察不同胁迫处理时间下新春6号小麦中DREB基因的表达情况,分析该基因对小麦抗逆性的影响。[结果]小麦的抗旱DREB基因受干旱胁迫诱导,与对照相比,在小麦干旱胁迫12 h后表达量上升。[结论]小麦的抗旱DREB基因可能参与小麦对干旱胁迫的应答,为研究小麦的抗旱分子机理提供了依据。[ Objective ] To analyze the expression characteristics of DREB gene from Xinchun No. 6 wheat.[ Method ] Under the drought ad- versity stress, the expression of DREB gene in Xinchun No. 6 wheat was investigated under different treatment time, the effects of the gene on wheat resistance were analyzed. [ Result] The results showed that wheat DREB gene is induced by drought stress. Compared with the control, the expression volume increased after 12 h drought stress. [ Conclusion] DREB gene maybe involved in response to drought stress, the study will provide a basis for wheat drought resistance molecular mechanism.
