Comparative genomic analysis of Clubroot resistance in the Brassicaceae family (original) (raw)
Clubroot, caused by the obligate biotroph Plasmodiophora brassicae, is one of the economically most important diseases of Brassica crops in the world including B. oleracea (coles), B. napus (oilseed rape) and B. rapa (turnip). The breeding of resistant cultivars is currently a main goal to control this disease in all Brassica crops. Very few resistant varieties are currently available especially for coles and oilseed rape. The model plant Arabidopsis thaliana is also a host for clubroot and shows natural variation in the responses to clubroot infection. Genetical genomics analyses of the plant response to clubroot infection are in progress in our team in order to determine which structural and functional characteristics of the resistance factors have to be taken into account to build resistant varieties in a complex environment. The aim of the present work was to investigate synteny of the regions carrying resistance factors to clubroot through a comparative structural study in the ...
