Abstrakt

Plants contain several mechanisms that help them cope with specific conditions during their life, such as extreme temperatures or pathogen attacks. One of these mechanisms is the activity of heat shock proteins (HSP) that are not only involved in protein folding mechanisms but can also participate in signaling cascades and protein interactions. Our analysis revealed the putative role of Plasmodiophora brassicae HSP in the interaction with its plant host. Here, we employed proteome analysis and showed HSP70 dynamics in the course of Plasmodiophora infection. Plasmodiophora brassicae is a global pathogen of the Brassica family with significantly limited options for control strategies. Our results indicate that the HSP70 family could be a valid target for promoting resistance against Plasmodiophora.
