The role of cytokinins in clubroot disease

ABSTRACT: Clubroot (Plasmodiophora brassicae) is a pathogen of Brassicaceae that causes significant reductions in yield as a consequence of gall formation in the root and hypocotyl of infected plants. The pathogen hijacks host vascular cambium development and cytokinins are implicated in this process. Microarray analysis was used to investigate changes in cytokinin metabolism during gall formation of clubroot-infected ipt1;3;5;7 mutants Arabidopsis thaliana. These mutants have severely restricted synthesis of host cytokinins (isopentenyl adenine and trans zeatin) and fail to form a vascular cambium and, as a consequence, do not undergo secondary thickening. Infection of these mutants allows the impact of pathogen-derived cytokinin synthesis to be observed.
