PPIB and infection: Four groups of oats genotypes can be also observed in the Figure 2 based on their response to the artificial inoculation with FC. In the “red” group of oats (Hronec, Vaclav, Važec and A. strigosa) the content of β-D-glucans was relatively high (>2.20%) in the control and increased after the infection with FC. The DON accumulation was middle to low as well as the presence of pathogen DNA was not very high.
