Hypoxia response in Arabidopsis roots infected by Plasmodiophora brassicae supports the development of clubroot

Background The induction of alcohol fermentation in roots is a plant adaptive responseto flooding stress and oxygen deprivation. Available transcriptomicdata suggest that fermentation-related genes are also frequently induced in roots infected with gallforming pathogens, but the biological significance of this induction is unclear. In this study, we addressed the role of hypoxia responses in Arabidopsis roots during infection by the clubrootagent Plasmodiophora brassicae.
