Expression matrix of chilling upregulated bZIP transcription factors. Expression values are represented by the means of two independent biological replicates (p < 0.05). Members of this group include the genes that were upregulated (≥log2 [1.8]) in at least two consecutive time points and not downregulated in any time point. Expression profiles in response to exogenous H2O2 are presented in a binary format, where the upregulated and not upregulated time points were assigned a value of 1 (blue) and 0 (black), respectively. Locus IDs are according to TIGR rice genome annotation.
