| Abstract: | Infection of Brassicaceae with the obligate biotrophic pathogen Plasmodiophora brassicae results in the development of root galls (clubroots). During the transformation of a healthy root to a root gall a plethora
of changes in primary and secondary metabolism occur. The upper part of an infected plant is retarded in growth due to redirection
of assimilates from the shoot to the root. In addition, changes in the levels of plant growth regulators, especially auxins
and cytokinins, contribute to the hypertrophy of infected roots. Also, defense reactions are manipulated after inoculation
of suitable host plants with P. brassicae. This review summarizes our current knowledge on the changes in these parameters. A model is presented for how primary metabolism
and secondary metabolism, including plant hormones, interact to induce clubroot formation. |
