Marker gene-assisted identification of stage-specific processes in P. capsici. (A) Expression of PcHmp1 (left panel), PcNpp1 (middle panel), and PcCdc14 (right panel) as determined by whole-genome microarray analyses and compared with the constitutive control gene β-tubulin. (B) Marker genes were used in cluster analyses to identify genes that were coregulated. The y-axis represents fold change in expression values, determined by calculating fold changes over mean expression values across all treatments. (C) Overview of significantly enriched ontologies present in marker coregulated genes. Dark bar shows the percentage of genes in the coregulated fraction compared with the background fraction (light grey). All ontologies shown were significantly enriched (P<0.05, false discovery rate <0.05).
