Abstract
Many transcription factors are involved in the progress of stress-inducible regulation. Transcription factors play an important role not only in stress tolerance but also in stress response. Some of the transcription factors and their target genes, whether in tolerance or in response, take part in the pathway metabolism. To explain the relationship between the transcription factor and target gene in Arabidopsis thaliana, gene regulation networks under salt and drought stresses were constructed. The regulation network showed that the transcription factor WRKY53 played a key role in the regulatory network through regulating ATWRKY18 and GBF3. The overlap of salt and drought stress regulation networks showed that degradation-related pathways were repressed, while alpha-linolenic acid and phenylpropanoid pathways were activated .
Key words: Regulation network, Arabidopsis thaliana, stress, pathway.
