Figure 10. The WRKY33 pathway leading to camalexin as related to H. schachtii infection.
The phosphorylation cascade involving WRKY33 leading to camalexin. P, phosphorylation. ↓ indicates that the expression of the gene is downregulated in syncytia induced by H. schachtii as compared to control root segments while = indicates no change in expression according to data from Szakasits et al. (2009). + and – indicate that increase or decrease leads to enhanced resistance or susceptibility, respectively.
