Genome-Wide Identification and Characterization of bZIP Transcription Factors in Brassica oleracea under Cold Stress

Figure 4

Heat map representation of cold-responsive expression of BolbZIP and BrbZIP genes. The expression pattern of the BolbZIPs and their closest BrbZIP homologs in response to cold (4°C) and freezing (−2°C) stresses are shown. Heat map was generated using up- and downregulated gene expression data from qRT-PCR and RT-PCR results.
