Results in Figure 3 suggest that there is a negative relationship between the content of β-D-glucans, the cell wall polysaccharide in oat grain and the manifestation of the infection caused by FG, that is, that the presence of higher β-D-glucans content in oat grain could evoke lower infection and thus higher protection of the plant against the infection with the FG. Another pair of vectors, β-D-glucans content after the FG infection and concentration level of DON provides the same opposite relationship. The gene discussed is PPIB; the disease is infection.
