Regulation of RAP2.4 expression in Arabidopsis wildtype plants. a Comparison of the transcript abundance regulation of the seven on the Affimetrix ATH1 gene chip represented RAP2.4 transcription factor genes during development on the Genevestigator platform. b Relative transcript abundance for all eight RAP2.4 transcription factor genes 1 week at 10 °C higher and lower temperature and after 2 h at elevated light intensity relative to the transcript level of plants kept at control conditions as obtained by qRT-PCR. The data are presented on a log₂-scale. The reference level (expression intensity at 20 °C; set to “1”) is marked with a line. All expression levels higher than the reference are shown as increase, all expression levels lower as decrease relative to the reference level. Statistical significance to the transcript levels under standard light and temperature conditions is labelled with asterisks
