General features of the chilling stress response transcriptome of japonica rice (cv. Nipponbare) based on the analysis of expression profiles across 10 time points. The composition of the non-overlapping upregulated (2,604 genes) and downregulated (6,064 genes) components are indicated. Venn diagram also shows the overlap between chilling and H₂O₂ response transcriptomes. For the upregulated component, 1,088 genes (86 transcription factors + 1,002 non-transcription factors) were induced by chilling but not by exogenous H₂O₂ and 1,516 genes (62 transcription factors + 1,454 non-transcription factors) were induced by both chilling and exogenous H₂O₂. For the downregulated component, 3,843 genes (266 transcription factors + 3,577 non-transcription factors) were repressed by chilling but not by exogenous H₂O₂ and 1,516 genes (82 transcription factors + 2,139 non-transcription factors) were repressed by both chilling and exogenous H₂O₂.
