Expression levels of pectinolytic enzyme genes in gongylidia relative to gongylidia-free mycelium measured with quantitative real-time polymerase chain reaction (qPCR). Bars are means ± SE (n = 4). Statistically significant results are marked with an asterisk. An equal level of gene expression between the two tissues gives a fold change of one (dotted horizontal line).
