[Construction and analysis of SOS pathway-related transcriptional regulatory network underlying salt stress response in Arabidopsis].
Elucidating gene regulatory network of Arabidopsis thaliana under high salt treatment is crucial to understand the defense mechanism of maintaining normal growth rate. Here, an Arabidopsis Salt Overly Sensitive (SOS) transcriptional regulatory network under salinity stress was constructed using a reverse engineering method on published genome-wide expression profiles. In this study, the SOS regulatory network constructed contains 70 genes, of which 27 are highly interconnected transcription factors. According to the expression feature of key genes in SOS signaling pathway, distinct expression patterns of the regulatory network were identified.
