Weeds promote greater arbuscular mycorrhizal fungi benefit in organically managed spring wheat (Triticum aestivum L.) cultivation system
DownloadFall 2012
Weeds appear to enhance soil microbial benefit in organic agricultuer. We examined effects of weed and microbial effects on spring wheat (Triticum aestivum L.) yield and quality under organic management systems. Canadian spring wheat cultivars were planted in weed-free and weedy treatments in...

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...

Spring 2014
Understanding the flowering gene complex in bread wheat is important to utilize the maximum production potential in a time-limited growing season. Vernalization (Vrn), photoperiod (Ppd) and earliness per se are the three genetic constituents of the flowering gene complex. A series of experiments...

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...

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...

Transcriptome analysis of the fungal pathogen Pyrenophora tritici-repentis, causal agent of tan spot of wheat
DownloadFall 2023
Tan spot, caused by the necrotrophic fungus Pyrenophora tritici-repentis, is a foliar disease of hexaploid and tetraploid wheat (Triticum aestivum and T. turgidum, respectively) that can cause significant yield and quality losses. Disease development involves the differential production of...

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...

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...
