WNK3 and infection: Evidence confirming this hypothesis is that relatively less downregulation of the studied genes occurred after infection with incompatible Prs isolates; in particular, the compatible strain caused a greater decrease in expression than the incompatible one in two cases involving Prs strains of different pathogenicity: ScLr1_4 in line D39 at 36 hpt, and ScRga2_6 in line L318 at 36 hpt.
