Outline of procedure for elucidating TUs by integrated analyses. (1) Co-expressed gene clusters predicted by correlating expression profiles between neighboring genes; (2) promoter (thin arrows) prediction by PWM as the start of a TU in the putative co-expressed gene clusters; (3) detection of significantly expressed genes (stripe thick arrows) by comparison between TF deletion mutant arrays and wild ones; (4) identification of genes composing putative TUs (filled thick arrows) by integration of the three analyses.
