Transcriptional regulation and selenite response. (A): T-profiler prediction of the transcription factors involved in the positive response of yeast to selenite. The color code is the same as for figure 1A. These predictions were based on previous ChIP-chip results . (B): Expression patterns of genes encoding transcription factors involved in stress response pathways. Full results are presented in additional file 1. Wild-type cells were treated with selenite and gene expression was evaluated by microarray analyses at different time points, using untreated cells as a reference.
