Molecular and functional characterization of sn-glycerol-3-phosphate acyltransferase of plants
DownloadSpring 2011
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...

Clubroot, caused by the soilborne pathogen Plasmodiophora brassicae, is a threat to cruciferous crops worldwide and an important disease of canola (Brassica napus L.) in Canada. At present, pathotypes of P. brassicae are distinguished phenotypically based on their virulence patterns on host...

The apparent bottleneck in the accumulation of oil during seed development in some oleaginous plant species is the formation of triacylglycerol (TAG) by the acyl-CoA-dependent acylation of sn-1,2- diacylglycerol catalyzed by diacylglycerol acyltransferase (DGAT, EC 2.3.1.20). Improving DGAT...

Fall 2020
Canola (Brassica napus L.) is an amphidiploid or allotetraploid (AACC, 2n = 4x = 38) crop plant and it is one of the most important oilseed crops in the world. The narrow genetic base of this crop, especially in its C genome, is not only a major impediment for its continued improvement but also...

Properties and Biotechnological Applications of Acyl‐CoA:diacylglycerol Acyltransferase and Phospholipid:diacylglycerol Acyltransferase from Terrestrial Plants and Microalgae
Download2018-07-30
Xu, Yang, Caldo, Kristian Mark P., Pal‐Nath, Dipasmita, Ozga, Jocelyn, Lemieux, M. Joanne, Weselake, Randall J., Chen, Guanqun
Triacylglycerol (TAG) is the major storage lipid in most terrestrial plants and microalgae, and has great nutritional and industrial value. Since the demand for vegetable oil is consistently increasing, numerous studies have been focused on improving the TAG content and modifying the fatty‐acid...

RNA helicases function as molecular motors that rearrange RNA secondary structure, potentially performing roles in any cellular process involving RNA metabolism. Although RNA helicase association with a range of cellular functions is well documented, their importance in response to abiotic stress...

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;...

STRESS RESPONSES OF THE FLAX GENOME: ACTIVATION OF TRANSPOSABLE ELEMENTS, DEFENSE GENES AND GENOME RESTRUCTURING AND DIVERSIFICATION.
DownloadSpring 2017
Transposable elements (TEs) are DNA sequences that can move in the genome (transpose) via a DNA or a RNA intermediate. TEs are abundant in plant genomes and can be activated by stress. Their activity can result in structural and gene expression alterations that increase diversity within and among...

Substrate preferences of long-chain acyl-CoA synthetase and diacylglycerol acyltransferase contribute to enrichment of flax seed oil with a-linolenic acid
Download2018-04-01
Xu, Yang, Holic, Roman, Li, Darren, Pan, Xue, Mietkiewska, Elzbieta, Chen, Guanqun, Ozga, Jocelyn, Weselake, Randall J.
Seed oil from flax (Linum usitatissimum) is enriched in a-linolenic acid (ALA; 18:3?9cis,12cis,15cis), but the biochemical processes underlying the enrichment of flax seed oil with this polyunsaturated fatty acid are not fully elucidated. Here, a potential process involving the catalytic actions...
