Fig. 5.
Time course expression analyses of PKS genes responding to confrontation with R. solani, S. sclerotiorum or F. oxysporum. X-axis: time points of confrontation with phytopathogens; Y-axis: mRNA expression (fold induction relative to β-tubin normalized). The fold change in PKS gene expression was calculated using the formula 2−ΔΔCT. White bars: expression responding to S. selerotiorum; horizontal bars: expression responding to R. solani; Black bars: expression responding to F. oxysporum. *Significant difference at 0.05 level (p < 0.05) by comparing T. harzianum 88 which was confrontation with three fungal plant pathogens and non- confrontation with three fungal plant pathogens. Arrows indicate the highest expression of PKS genes responding to different phytopathogens.
