Fold changes of relative expression of hydrophobin transcripts.

<p>(A) Mycelium grown on soil (substrate mycelium), immersed and floating mycelium compared to solid medium. (B) Liquid culture treated with root exudates of <i>P</i>. <i>abies</i> or <i>P</i>. <i>sylvestris</i>, and (C) with ethanol (EtOH) and indole-3-acetic acid (IAA) both compared with non-treated liquid culture. (D) Response to volatiles from mycelia grown on solid medium, next to roots of <i>P</i>. <i>abies</i> or <i>P</i>. <i>sylvestris</i>, and (E) in ectomycorrhiza with <i>P</i>. <i>abies</i> or <i>P</i>. <i>sylvestris</i> both compared to a control on solid medium. (F) Fruiting bodies compared to artificial medium and soil. Bars denote standard error, significance level * <i>P</i> < 0.05, ** <i>P</i> < 0.005, *** <i>P</i> < 0.005.</p>
