Table 4 Summary of Transcriptional Regulation of Target Genes (Table 2) and Transcription Factor Genes (Table 3). The Table Represents the Number of Response Elements Present in the Promoter Region of Differently Expressed Cold/Light (C/L) or Cold/Dark (C/D) or Dark (D)-Responsive Genes. Promoter Analysis Was Performed within 500 bps Upstream of Transcription Start Site using a Genomatixâ„¢ and Athena Programs. Response Elements that Are More than 90% Same within a Group of Expressed Genes are underlined According to Genomatix Gene2Promoter Analysis. Enriched Response Elements within the Same Groups of Genes (P-value < 10e-3) Are Indicated as Underlined and Bold According to Athena Visualization Program [71].
From: Light has a specific role in modulating Arabidopsis gene expression at low temperature
