Background and objectives
Among the proteins found in plants, the pathogenesis-related proteins (PR proteins), are thought to be involved in disease resistance. In vitro studies showed that they exhibit an antifungal activity . Moreover, in many pathosystems, disease resistance was often associated with detection of some PR proteins . The aim of this study was to analyse the relationships between resistance of cauliflower to downy mildew caused by Peronospora parasitica and the accumulation of PR proteins.
