Hypothetical models of chilling stress transcriptional regulatory network. (A) phase-1 clusters; (B) phase-2 and phase-3 clusters. Models were based on integrative analysis of temporal co-expression, promoter motif enrichment and responses to oxidative mimic (see Figures 6 and 7). Each expression cluster is connected with all possible transcriptional regulator(s) based on coordinate expression patterns and over-representation of the target cis-elements associated with that class of transcription factor. Heavy green line represents the primary regulatory mechanism (most enriched elements). Solid black and dotted gray lines represent secondary and tertiary regulatory mechanisms, respectively.
