A proteome-level analysis of the canola/Sclerotinia sclerotiorum interaction and sclerotial development
DownloadFall 2010
The fungal pathogen Sclerotinia sclerotiorum (Lib.) de Bary is capable of infecting over 400 plant species including canola (Brassica napus L.). The fungus secretes oxalic acid (OA), which plays an important role in infection and disease progression. An analysis of proteome-level changes...

Abiotic and biotic factors influencing host-plant use of a generalist herbivore through plant-mediated interactions: oviposition and larval performance by the bertha armyworm, Mamestra configurata Walker (Lepidoptera: Noctuidae) on canola
DownloadFall 2018
The bertha armyworm (BAW), Mamestra configurata Walker (Lepidoptera: Noctuidae), is a native, polyphagous herbivore which feeds on a variety of plants in different families. In the Prairie Provinces, canola, Brassica napus L. (Brassicaceae), is a preferred host, making BAW a significant pest....

An assessment of the fumigant metam sodium and a Brassica juncea-derived biofumigant as management tools for clubroot (Plasmodiophora brassicae) of canola (Brassica napus)
DownloadFall 2016
Clubroot of crucifers, caused by the soilborne parasite Plasmodiophora brassicae, is spreading across canola (Brassica napus) fields in Alberta, Canada. Dissemination of the parasite is associated with the movement of infested soil on farm and other machinery, with the disease generally...

Assessments of novel transgenic germplasm and treatment with the phytohormone cytokinin for reducing feeding damage by flea beetles, Phyllotreta spp. (Coleoptera: Chrysomelidae) in canola
DownloadFall 2011
Flea beetles Phyllotreta cruciferae (Goeze) and Phyllotreta striolata (Fabricius) (Coleoptera: Chrysomelidae) pose significant threats to early canola seedling establishment. The resistance potential of transgenic Brassica napus expressing cDNA encoding pea PR10.1 and 10.4 (ABR17) in Westar and...

Broadening of genetic diversity in spring canola (Brassica napus L.) by use of C genome of B. oleracea var. capitata, and the effect of this on the performance of the inbred lines and their test-hybrids
DownloadFall 2018
Broadening the genetic base of spring B. napus canola is important for continued progress in breeding of hybrid cultivars. The objectives of this study were to (i) assess the potential of the C genome of B. oleracea var. capitata (cabbage) for broadening the genetic base of the C genome of B....

Broadening of genetic diversity in spring canola (Brassica napus L.) by use of yellow sarson and Canadian spring Brassica rapa L.
DownloadFall 2015
Canada is the top producer of Brassica oilseeds [B. napus L. (n = 19, AC genome)] in the world. Genetic diversity has declined in this crop in the recent years due to use of only superior and genetically narrow gene pool in breeding. Presence of adequate genetic diversity is important for further...

Fall 2019
Rutabaga (Brassica napus ssp. napobrassica (L.) Hanelt) is widely grown as a vegetable crop and animal fodder, and is reported to be an excellent source of clubroot (Plasmodiophora brassicae) resistance genes. In this study, the genetic diversity and clubroot resistance of 124 rutabaga accessions...

Design and analysis of population demographic experiments for use in environmental risk assessments for genetically modified crops
DownloadFall 2016
Genetically modified crops with putative fitness-enhancing traits are being field-tested throughout Canada and the world, but robust methods with which to compare their fitness with conventional cultivars are lacking. Additionally, field analyses of GM crops in non-agricultural areas are...

Development and Validation of a Sclerotinia sclerotiorum-Specific Quantitative PCR Assay to Assess Risk of Sclerotinia Stem Rot of Canola (Brassica napus)
DownloadFall 2016
Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is a major disease of canola (Brassica napus) commonly managed by the routine application of fungicides. Petal infestation is an important stage of the disease cycle and has been the focus of previously developed Sclerotinia stem rot risk...

Effect of modulation of auxin response on clubroot development caused by Plasmodiophora brassicae in Arabidopsis
DownloadSpring 2024
Clubroot disease caused by the obligate biotrophic protist Plasmodiophora brassicae, is a serious soilborne disease in Brassicaceae species including cruciferous crops such as canola and the genetic model species Arabidopsis. This disease, identified by the formation of sizable root galls, is...
