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.
