Volcano plots of genes showing altered expression in both natural isolates and mutants. Log2 fold changes and their corresponding p-values of all genes in the microarray were considered to build the Volcano plot. Genes up-regulated (>1.5 fold change, p < 0.05) are depicted in red box. Genes down regulated (>1.5 fold change, p < 0.05) appear in blue boxes. Genes that did not show a significantly modified pattern are represented in grey dots.
