Mendel. The efficacy of this resistance was studied in greenhouse exper- iments using two Plasmodiophora brassicae isolates, which were either virulent (P1(+)) or avirulent (P1) on Mendel. Seeds of clubroot-susceptible cultivar Visby and clubroot-resistant cultivar Mendel were sown in soil mixtures inoculated with different concentrations of resting spores (101, 103, 105, and 107 resting spores/g soil). Clubroot severity, plant height, shoot and root weight as well as resting spore propagation were assessed for each isolate and cultivar separately at four dates after sowing. The OSR cultivars behaved significantly different in the measured parameters.

  • Studies of Pathogenicity in Plasmodiophora Brassicae and Segregation of Clubroot Resistance Genes from Brassica Rapa Subsp
    Studies of pathogenicity in Plasmodiophora brassicae and segregation of clubroot resistance genes from Brassica rapa subsp. rapifera by Junye Jiang A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Plant Science Department of Agricultural, Food and Nutritional Science University of Alberta © Junye Jiang, 2020 Abstract The planting of clubroot resistant (CR) canola (Brassica napus) is the most effective method to manage clubroot, a soilborne disease caused by Plasmodiophora brassicae. In recent years, many P. brassicae isolates capable of overcoming resistance have been detected, often in mixtures with avirulent isolates. To improve understanding of the effect of low concentrations of virulent isolates on host resistance, three CR canola cultivars (‘45H29’, ‘L135C’ and ‘L241C’) were inoculated with pairs of isolates representing virulent/avirulent pathotypes (2*/2, 3*/3 and 5*/5) of P. brassicae, collected after or before the introduction of CR canola, respectively. Clubroot severity was significantly higher in all nine experimental treatments (low virulent + high avirulent) than in the negative control NC1 (high avirulent), and higher in seven of nine experimental treatments than in the negative control NC2 (low virulent). Disease severity was positively correlated with P. brassicae biomass in planta, as determined by quantitative PCR analysis 28 - 35 days after inoculation (dai). These results suggest that low concentrations of virulent isolates compromised the clubroot resistance in canola, facilitating infection by avirulent isolates. In a second study, the expression of 205 P. brassicae genes encoding putative secreted proteins was compared following inoculation of the canola ‘45H29’ with pathotypes 5I (avirulent) and 5X (virulent) of the pathogen.

This disease is widely distributed where these crops are grown and is particularly severe in older market garden areas. Symptoms Infection occurs on roots at any stage of growth. Symptoms do not become obvious until knotted swellings Figure 2. Chinese cabbage affected by clubroot. form on the roots. The first above ground symptom is usually wilting, Biology particularly during hot-dry weather. Severely diseased Survival plants are generally stunted, and the foliage may be different in colour from healthy plants. P. brassicae spores can remain viable in the soil for at least 20 years, even in the absence of a susceptible host. Infected roots show characteristic swellings or knots. Normal root growth does not occur on severely infected Resting spores germinate under moist conditions and taproots of young plants which form a single-clubbed root. release swimming spores that infect tiny root hairs. The fungus multiplies rapidly in the root hair and releases more swimming spores which reinfect the roots. During the secondary stage of the lifecycle, the fungus continues to multiply within the root causing the root tissues to swell. This leads to the formation of galls which are characteristic of clubroot. Infected root cells contain millions of fungal spores.

    Clubroot in canola and cabbage in relation to soil temperature, plant growth and host resistance By Thomas Vinzenz Gludovacz A Thesis presented to The University of Guelph In partial fulfillment of requirements for the degree of Master of Science in Plant Agriculture Guelph, Ontario, Canada © Thomas Vinzenz Gludovacz, May, 2013 ABSTRACT CLUBROOT IN CANOLA AND CABBAGE IN RELATION TO SOIL TEMPERATURE, PLANT GROWTH AND HOST RESISTANCE Thomas Vinzenz Gludovacz Advisors: University of Guelph, 2013 Dr. Mary Ruth McDonald Dr. Bruce D. Gossen The effects of diurnal temperature fluctuation and the utility of degree days for modeling clubroot on canola (Brassica napus L.) caused by Plasmodiophora brassicae Woronin were assessed using microscopy and qPCR, and in field trials. Temperature fluctuation had little effect on pathogen development. The optimal temperature for root hair infection was 25° C. Air and soil degree days and rainfall were used as metrics for estimating clubroot development, with only limited success. Several cultivars of cabbage (Brassica oleracea L. var. capitata) with unknown clubroot resistance mechanism(s) were assessed using staining and microscopy, and qPCR. In field trials, ‘Bronco’ was susceptible to clubroot (100 DSI), ‘Kilaherb’ was resistant (0 DSI), and ‘B-2819’ was intermediate (53 DSI). Plasmodiophora brassicae was present in cortical tissue of all cultivars. A delayed disease phenotype in ‘B-2819’ may indicate a quantitative resistance genotype that could be exploited in research on resistance genes and breeding.

Secor Co-Chair Dr. Neil C. Gudmestad Co-Chair Dr. Asunta L. Thompson Dr. Luis E. del Rio Mendoza Approved: 11/02/2015 Dr. Jack B. Rasmussen Date Department Chair ABSTRACT The biotroph protozoan Spongospora subterranea causes root gall formation and powdery scab on potato. Symptoms on tubers affect directly the quality and marketability of the harvested product while infection in roots are associated with yield reductions. Moreover, S. subterranea is the vector of the Potato mop-top virus. The management of the disease is difficult due to the limited number of current control options and requires the integration of control measures among which host resistance represents the most economically and long-term approach. This dissertation focuses on the evaluation of management strategies for the control of powdery scab and root gall formation.

  • Clubroot of Cabbage and Other Crucifers
    report on RPD No. 923 PLANT July 1989 DEPARTMENT OF CROP SCIENCES DISEASE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN CLUBROOT OF CABBAGE AND OTHER CRUCIFERS Clubroot of cabbage and other crucifers, caused by the soilborne fungus Plasmodiophora brassicae, is widely distributed worldwide wherever plants of the mustard family (Crusiferae) are grown. It can cause serious losses in soil that has become infested. Soil commonly remains infested for many years even in the absence of susceptible host plants. Besides cabbage, such related vegetables as broccoli, Brussels sprout, Chinese cabbage, cauliflower, collard, garden cress, horseradish, kale, kohlrabi, mus- tards, radish, rape, rutabaga, sea kale, turnip, and watercress may become Figure 1. Clubroot of cabbage (BASF photo). infected. Such popular garden flowers as alyssum, candytuft, dames-violet, honesty (Hesperis), peppergrass, rockcress, stock, sweet alyssum, wallflower (Erysimum), and western wallflower occasionally become infected. Most cruciferous weeds, including charlock, pennycress, shepherd’s purse, wild mustards, wild radish, and yellow-rocket or wintercress are susceptible and serve to perpetuate the causal fungus between crops. The fungus also infects a few plants outside the cabbage or mustard family including corn poppy, mignonette, red clover, and ryegrass. SYMPTOMS Plants infected with clubroot become unthrifty, grow slowly, and appear stunted with pale green to yellowish leaves. The leaves may wilt on bright dry days and partly recover at night. The lowest and outer leaves may turn yellow and often drop prematurely. Plants may die before maturing or fail to produce a marketable head. When diseased plants are dug, the root system appears greatly distorted with a mass of small to large, spindlelike, knobby, or club-shaped swellings (Figure 1 and Figure 2, 9-11).

(2016): Clubroot caused by Plasmodiophora brassicae Wor.: a review of emerging serious disease of oilseed rape in the Czech Republic. Plant Protect. Sci., 52: 71–86. Winter oilseed rape is the second most frequently grown crop in the Czech Republic. Clubroot, caused by Plasmo- diophora brassicae (Wor.), was previously a problem in production of vegetable. The disease has been spreading on winter rape (Brassica napus L.) over the past four years. Infected stands were reported throughout the country in autumn 2011. The pathogen is probably widely spread in the whole country, its incidence depends on suitable weather conditions. Every field with clubroot is considered as contaminated for many years. The amounts of inoculum and its distribution are not sufficient yet, but this is just the initial stage of colonisation. There is a similar situation resem- bling experiences from other countries (Canada, Germany) where clubroot has gradually expanded in the last 15 years. Keywords: winter oilseed rape; Brassica napus L.; clubroot disease; biology; pathopypes; resistance Introduction including oilseed rape (Hwang et al. 2012).

  • Evaluation of Management Strategies for Clubroot Disease of Brassica Crops
    Evaluation of Management Strategies for Clubroot Disease of Brassica Crops Gideon Porth, Frank Mangan, Robert Wick, and Wesley Autio University of Massachusetts, Amherst, MA Clubroot disease, caused by the pathogen Plasmodiophora brassicae, is the most devastating disease of Brassica crops worldwide. It is found throughout temperate climates and is especially significant in areas of intensive production of Brassica crops such as East Asia, Northern Europe, Australia, and North America. The disease can effect all types of cruciferous crops including vegetables (cabbage, cauliflower, radish, turnip, Chinese cabbage), oil crops (rape seed), fodder crops (swedes and fodder turnip), and ornamentals (stock and sweet alyssum), as well as weeds such as wild mustards. Disease occurs when the soil-borne club root pathogen invades the plant’s root system. The infected roots become swollen forming galls or “clubs” that interfere with the plant’s water and nutrient uptake. In mild cases wilting and stunting occurs, and in severe cases, the plant dies. Galls begin as small legions, often on lateral roots, and grow over time, often affecting the entire root system of the host (Figure 1). Disease Management Many different strategies for managing clubroot have been researched and implemented since it was first reported by Woronin in 1878. One of the most documented treatments is raising the soil pH to 7.1- 7.2. This creates an unfavorable soil environment for the pathogen, most likely by disrupting the release of zoospores. It is unclear whether the suppressive effects of this treatment are Figure 1: Healthy roots of Chinese cabbage grown in disease free soil due solely to an increase in (left) and clubbed roots of mustard greens grown in clubroot infested pH, the associated increase soil (right).
