CAT and infection: It should be noted that the Snn1–SnTox1 compatible interaction (Om35/Sn9MN) did not lead to an increase in CAT activity, a decrease in the transcript level of TaRbohF gene and a reduction in the mRNA content of TaRbohD and TaSod genes 24 h after infection in comparison with another compatible interaction Snn3–SnTox3 (Kaz10/SnB) (Figure 4 and Figure 5).
