Averaged regulation of all genes (|log
(ratio)| > 1.5) involved in mycoparasitsm of T. reesei , T. atroviride and T. virens during the three confrontation stages with R. solani (BC, C and AC). Vertical bars denote 0.95 confidence intervals. The same letters above the bars indicate the statistical significance (ANOVA) between the stages of each species: for m–n–r p < 0.005; s–t p < 0.02; u–z p < 0.001. The plot shows different trends of gene expression kinetics between the species and does not reflect the gene regulation intensity differences among the species.
