摘要: 为研究盐胁迫对水稻转录因子表达的影响,整合GEO数据库中关于水稻盐胁迫相关的基因芯片信息,利用相关的生物信息学方法筛选出差异表达的转录因子。结果显示:敏感品种有10个转录因子转录水平表达方向一致(8个上调表达,2个下调表达);耐受品种有10个转录因子转录水平表达方向一致(2个上调表达,8个下调表达)。1个转录因子HSF在敏感品种和耐盐品种间表达方向一致。盐胁迫下水稻转录因子相关基因的表达发生变化,不同水稻品种既表现品种特异性,也存在部分重叠。该结果为进一步分析水稻转录因子在响应盐胁迫过程中的作用机制提供了理论参考。

Abstract: The research was conducted to study the effects of salt stress on rice by changes in expression of transcription factors.The dates of complete genomic expression profiles from rice were obtained from GEO database,and the changes in expression of transcription factors were identified by bioinformatics analysis.The results showed that the expression levels of 10 transcription factor genes(8 up-regulated and 2 down-regulated)in susceptible rice and 10(2 up-regulated and 8 down-regulated)in resistant rice were induced by salt stress.The direction of the change in expression for transcription factor HSF was consistent between sensitive and salt-tolerant varieties,and among the transcription factors are those with specificity,as well as overlap,among the different rice varieties.This study provided theoretical references for further analyzing the mechanisms of transcriptional factors in the response of rice to salt tolerance.
