Spring 2018
MicroRNAs (miRNAs) are small non-coding RNAs, which are known to regulate plant responses to abiotic stresses, such as Cold Stress (CS) and during normal growth and development. In Brassica napus (canola), miRNAs regulate various developmental processes and responses to metal stress however;...

Sensitivity of Leptosphaeria maculans isolates to pyraclostrobin and assessment of fungicide efficacy in the management of blackleg of canola
DownloadFall 2016
Blackleg (Leptosphaeria maculans) disease is endemic to canola (Brassica napus) worldwide. With shortened canola rotations and increasing levels of blackleg in Alberta, Canada, growers may look to fungicides as an attractive disease management tool. However, the improper or intensive use of...

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...

The effects of soil and plant nutrients on the oviposition preference, larval performance and spatial dynamics of Ceutorhynchus obstrictus and its parasitoids
DownloadFall 2010
The effects of nitrogen and sulfur fertilization on the oviposition, feeding preferences, and larval performance of Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae) on Brassica napus L. were examined in a series of laboratory experiments. The associations between C. obstrictus...

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...

The role of auxin and indole glucosinolates in defense against clubroot infection in Brassica napus
DownloadFall 2023
Abstract Clubroot, caused by the obligate parasite Plasmodiophora brassicae, is one of the most damaging diseases of the Brassicaceae. Glucosinolates (GSLs) are a group of defense-related secondary metabolites in cruciferous plants that have been associated with clubroot disease. The breakdown of...

Transcriptomic responses in spring canola carrying clubroot resistance introgressed from rutabaga or “Mendel”
DownloadFall 2020
Canola provides ~15% of the total global vegetable oil supply and is an important crop contributing about $26.7 billion to Canada’s economy. Canola production has been threatened by clubroot disease caused by Plasmodiophora brassicae Woronin, which in extreme case can result complete crop...

Type-1 Brassica napus Diacylglycerol Acyltransferases: Enzyme Characterization and Molecular Tools for Increasing Storage Lipid Production in Yeast
DownloadFall 2015
Diacylglycerol acyltransferase (DGAT) catalyzes the final step in the acyl-CoA- dependent biosynthesis of triacylglycerol (TAG). The level of DGAT activity may have a substantial effect on the flow of carbon into TAG in many organisms. In plants, yeast, and animals, two families of...

Understanding the role of diets enriched in long chain fatty acids on postpartum reproductive function and embryo development in dairy cows
DownloadSpring 2016
The objectives of this work were to investigate the influence of diets enriched in long chain fatty acids on feed intake, calf birth weight, maternal and neonatal fatty acid profiles, milk production, postpartum reproductive function, early embryonic development and its transcriptome profile in...
