Identification and genetic mapping of resistance genes against Canadian pathotypes of Plasmodiophora brassicae in Brassica rapa and Brassica napus
DownloadFall 2022
Clubroot (Plasmodiophora brassicae) is an important disease of canola/rapeseed (Brassica napus) and other crucifers. In this study, resistance loci/genes effective against P. brassicae pathotypes 2B, 3A, 3D, 3H, 5C, 5X and 8J were identified and mapped via genotyping-by-sequencing, QTL analysis,...

Roads are a prevalent, ever-increasing form of human disturbance on the landscape. In many places in western North America, energy development has brought human and road disturbance into seasonal winter range areas for migratory elk. In this population, I studied individual habitat selection...

Pathotypes of Plasmodiophora brassicae from clubroot resistant canola and assessment of amisulbrom for clubroot control
DownloadSpring 2021
Clubroot, caused by Plasmodiophora brassicae Woronin, is an important soilborne disease of canola (oilseed rape; Brassica napus L.). In Canada, clubroot management relies heavily on the planting of resistant cultivars, but since 2013, resistance has been broken in an increasing number of fields....

Strelkov, Stephen E., Hwang, Sheau-Fang, Howard, Ronald J., Hartman, Murray, Turkington, T. Kelly
Clubroot, caused by the obligate parasite Plasmodiophora brassicae Woronin, has recently emerged as an important disease of canola (Brassica napus) in central Alberta. Disease development is characterized by the formation of large galls on the roots of affected plants, which hinder water and...

Spatial and Temporal Variations in Tree Growth, Mortality, and Biodiversity in Alberta Forests
DownloadSpring 2014
Understanding the spatial and temporal variation of tree demographic rates and biodiversity is essential for predicting the dynamics of forest ecosystems and their responses to changing environments. This thesis contributes to that understanding through modeling the long-term change in tree...

Spheroidal gall formation and seedborne infestation by Plasmodiophora brassicae as overlooked aspects of clubroot biology and epidemiology
DownloadFall 2011
Plasmodiophora brassicae, the causal agent of clubroot, can infect many species of the Brassicaceae. Infection results in the formation of galls on the roots of susceptible plants. Most galls are spindle-shaped, but spheroid galls can also develop and are regarded as resistance structures....

Fall 2021
Clubroot, caused by Plasmodiophora brassicae, is an important soilborne disease of canola (oilseed rape; Brassica napus). The effective and sustainable management of clubroot requires a deeper understanding of clubroot epidemiology and improved durability of host resistance. This research aimed...

Clarke, Wayne E., Taheri, Ali, Rolfe, Stephen A., Malinowski, Robert, Haddadi, Parham, Links, Matthew G., Kagale, Sateesh, Strelkov, Stephen E., Djavaheri, Mohammad, Robinson, Stephen J., Parkin, Isobel A. P., Borhan, M. Hossein
Background The protist Plasmodiophora brassicae is a soil-borne pathogen of cruciferous species and the causal agent of clubroot disease of Brassicas including agriculturally important crops such as canola/rapeseed (Brassica napus). P. brassicae has remained an enigmatic plant pathogen and is a...

The Impact of Clubroot Resistant Canola Cultivars on Plasmodiophora brassicae Resting Spore Concentrations in the Soil
DownloadFall 2016
The soilborne pathogen Plasmodiophora brassicae Woronin, causal agent of clubroot of canola (Brassica napus L.), is difficult to manage due to the longevity of its resting spores, its ability to produce large amounts of inoculum, and the prohibitive costs of effective fungicides. The cropping of...
