Transcriptional regulatory networks in response to salt and drought stress in Arabidopsis thaliana
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...
