New OA Article: "Virulence on Pm4 kinase-based resistance is determined by two divergent wheat powdery mildew effectors" rdcu.be/eY3ED AvrPm4 effector / wheat Pm4. The pathogen can evade Pm4 recognition by expressing the suppressor SvrPm4, an RNase-like effector.

Targeting of the barley cell-surface receptor SRF3 by the Blumeria hordei effector AVRA13 overlaps with AVRA13 recognition by MLA and the induction of NLR-mediated cell death.
Pathogens secrete effector proteins to promote virulence. Despite their recognition by barley Mla resistance genes, the structurally-related Blumeria hordei ( Bh ) AVRA effectors are maintained in the...
