Figure 5

Hierarchical cluster analysis of relative transcript levels of hemicellulase genes in the transcription factor deletion strains versus the wild-type strain monitored by quantitive real time-PCR after exposure to L-arabinose for 4 h. Data are shown as a heat map with the following color code of relative expression values (navy: 6; white: 0; firebrick: -6; numbers indicate the log2 of the relative expression level, n = 2). Strains were precultured in 2% D-glucose for 16 h, washed, and transferred into minimal medium with 2% L-arabinose for an additional 4 h. Transcript levels of hemicellulase coding genes were assessed relative to those in the wild-type strain within each experiment. The experiment used actin as the internal standard. The values given in the figures are the means of three independent experiments.
