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.

了解俱乐部的根源-了解俱乐部病原体对发育的操纵
brassicae Plasmodiphora Wor。,夜叉根病原体是“非典型”植物病原体的完美例子。这种土壤传播的原生生物和专性生物营养寄生虫感染十字花科作物的根部,引发溃疡或溃疡,导致枯萎、生产力下降和植物死亡。与许多其他农业相关的病理系统不同,对夜根病和疟原虫-宿主相互作用的分子机制的研究是有限的。在发布了第一个芸苔属基因组序列并随后获得了转录组数据后,夜叉根研究界认为植物激素参与了夜叉根病原体对宿主发育的操纵。在此,我们回顾了导致根结石形成的主要事件,并描述了选择的植物激素的调节可能是调节植物宿主发育以造福病原体的关键。效应-宿主相互作用是病原体劫持植物细胞过程的不同策略的基础。这就是我们怀疑夜叉根病原体劫持宿主植物代谢和发育以诱导营养库根溃疡的原因,强调需要加深我们对这种主要操纵者的理解。

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.
