Brassica napus L. (AACC, 2n = 38) canola is the most extensively cultivated Brassica oilseed crop in the world; it is one of the most important field crops in Canada. The narrow genetic diversity in this crop is considered one of the major hindrances for continued improvement of this crop for...

Clubroot disease caused by Plasmodiophora brassicae is a serious threat to canola (Brassica napus) production. The evolution of new pathotypes has rendered available resistances ineffective and has necessitated the introgression of new resistance into canola and furthering our understanding of...

Yellow seed in Brassica oilseed crops is favoured for its association with lower fibre and higher oil contents. Yellow-seeded Brassica napus lines have been developed through introgression of this trait from its allied species; however, the trait in B. napus is often influenced by environmental...

Diacylglycerol acyltransferase 1 (DGAT1) catalyzes the acyl-CoA-dependent biosynthesis of triacylglycerol, the predominant component of seed oil. In some oil crops, including Brassica napus, the level of DGAT1 activity can have a substantial effect on triacylglycerol production....

The oil from flax (Linum usitatissimum L.) has high amounts of α-linolenic acid (ALA; 18:3cisΔ9,12,15) and is one of the richest sources of omega-3 polyunsaturated fatty acids (ω-3-PUFAs). To produce ∼57% ALA in triacylglycerol (TAG), it is likely that flax contains enzymes that can efficiently...

Further improving of seed yield, other agronomic and seed quality traits in spring canola Brassica napus requires broadening of genetic diversity in this crop. The European winter oilseed B. napus is known to be genetically diverse from spring oilseed B. napus. We hypothesized that elite spring...

Verticillium stripe, caused by Verticillium longisporum, is an emerging soilborne disease of the Canadian canola (Brassica napus) crop. This study aimed to refine techniques for inoculating the pathogen on canola and to quantify its impact on hybrid canola yield under greenhouse and field...

Seed oils of flax (Linum usitatissimum L.) and many other plant species contain substantial amounts of polyunsaturated fatty acids (PUFAs). Phosphatidylcholine (PC) is the major site for PUFA synthesis. The exact mechanisms of how these PUFAs are channeled from PC into triacylglycerol (TAG) needs...

Clubroot disease caused by Plasmodiophora brassicae Woronin is a serious threat to canola production in Canada. Most of the available clubroot-resistant canola cultivars carry major resistance genes of the Brassica A genome. However, the ineffectiveness of this type of resistance has been...

sn-Glycerol-3-phosphate acyltransferase (GPAT) catalyzes the acylation of sn-1 position of sn-glycerol-3-phosphate to produce lysophosphatidic acid and Coenzyme A. GPATs are involved in several lipid synthetic pathways and play important physiological roles in plant development. The present...
