Effector that triggers cell death in a variety of plant species (including tobacco, tomato and soybean), regardless of the Rps genes present. Avh241 interacts with the plant immune system via at least two different mechanisms, one recognized by plants dependent on subcellular localization and one promoting infection independent on membrane localization. The cell death triggered by Avh241 in N.benthamiana requires the two host mitogen-activated protein kinases, MEK2 and WIPK
