Differentially expressed genes may encode regulators of light-dependent differentiation.

<p>Relative expressions of the genes (i.e. log2-normalized intensities scaled by gene) in the four conditions (16 hybridizations) were clustered and depicted by color scale, where shades of green and red represent under- and overexpressed genes, respectively. Homologues in <i>N. crassa</i> were identified by a bidirectional best-hit (BDBH) approach. Light-induced genes in <i>B. cinerea</i> and <i>N. crassa</i> are marked with orange asterisks. For more details see <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004040#pgen.1004040.s013" target="_blank">Table S3</a>. (<b>A</b>) Expression of most photoreceptor-encoding genes is similarly induced by light in wild type and Δ<i>bcltf1</i> strains. All predicted photoreceptors were clustered. (<b>B</b>) Expression levels of 45 TF-encoding genes are altered in response to light or deletion of <i>bcltf1</i>. TFs that were differentially expressed in at least one condition were subjected to clustering.</p>
