<i>In planta</i> normalized <i>oah</i> transcript copy number at sampling times 1, 2, 4, 8, 12, 24, 48 and 72 hours post-inoculation.

<p>All <i>oah</i> gene expression values are represented normalized to the housekeeping gene, <i>actin</i>. Error bars on both graphs represent the standard error among 3 biological replicates. Asterisks represent values that are significantly different using a split plot factorial repeated measures analysis. <b>A.</b> The first trial included the necrotrophic generalists, <i>Botrytis cinerea</i> and <i>Sclerotinia sclerotiorum</i>, a host specialist of unknown trophic type, <i>S. glacialis</i>, and the biotrophic specialists, <i>Myriosclerotinia scirpicola</i> and <i>Myriosclerotinia duriaeana</i>. <b>B.</b> The second trial included the necrotrophic generalists, <i>Botrytis cinerea</i> and <i>Sclerotinia sclerotiorum</i>, the necrotrophic specialists, <i>B. tulipae</i>, <i>Monilinia fructicola</i>, and <i>Monilinia aucupariae</i>, and the biotrophic specialist, <i>Myriosclerotinia curreyana</i>.
