Cover Story: We introduce a novel target to control clubroot disease (Plasmodiophora brassicae), which is among the most damaging diseases worldwide for brassica crops. Its control via the salicylic acid (SA) defense pathway is not possible, since a P. brassicae effector methylates SA in infected roots and constitutive high SA levels influence plant growth negatively. Oxidation resistance is a family of eukaryotic proteins also found in brassicas. Overexpression of the mitochondrial member OXR2 from Arabidopsis thaliana can improve resistance to clubroot disease by increasing the constitutive pathway of SA defense. Consequently, transgenic plants show reduced clubroot symptoms with improved plant growth in comparison to wild type, and the pathogen was reduced in hypertrophied roots.
