Abstract
Plasmodiophora brassicae Wor., the clubroot pathogen, is the perfect example of an “atypical” plant pathogen. This soil-borne protist and obligate biotrophic parasite infects the roots of cruciferous crops, inducing galls or clubs that lead to wilting, loss of productivity, and plant death. Unlike many other agriculturally relevant pathosystems, research into the molecular mechanisms that underlie clubroot disease and Plasmodiophora-host interactions is limited. After release of the first P. brassicae genome sequence and subsequent availability of transcriptomic data, the clubroot research community have implicated the involvement of phytohormones during the clubroot pathogen’s manipulation of host development. Herein we review the main events leading to the formation of root galls and describe how modulation of select phytohormones may be key to modulating development of the plant host to the benefit of the pathogen. Effector-host interactions are at the base of different strategies employed by pathogens to hijack plant cellular processes. This is how we suspect the clubroot pathogen hijacks host plant metabolism and development to induce nutrient-sink roots galls, emphasizing a need to deepen our understanding of this master manipulator.
期刊介绍:
Seminars in Cell and Developmental Biology is a review journal dedicated to keeping scientists informed of developments in the field of molecular cell and developmental biology, on a topic by topic basis. Each issue is thematic in approach, devoted to an important topic of interest to cell and developmental biologists, focusing on the latest advances and their specific implications.
The aim of each issue is to provide a coordinated, readable, and lively review of a selected area, published rapidly to ensure currency.
