Engineering Enhanced Performance in Plant Diacylglycerol Acyltransferase and Long-Chain Acyl-CoA Synthetase
DownloadSpring 2018
Triacylglycerol (TAG) is the major storage lipid in higher plants and has great nutritional and industrial value. Plant storage lipid biosynthesis involves different subcellular compartments and a complex network of enzymes and proteins. Among them, endoplasmic reticulum (ER)-bound diacylglycerol...

Evolutionary and biochemical characterization of a Chromochloris zofingiensis MBOAT with wax synthase and DGAT activity
Download2021-01-01
Xu, Yang, Pan, Xue, Lu, Junhao, Wang, Juli, Shan, Qiyuan, Stout, Jake, Chen, Guanqun
Abstract: Wax synthase (WS) catalyzes the last step in wax ester biosynthesis in green plants. Two unrelated subfamilies of WS including the bifunctional acyltransferase and plant-like WS have been reported, but the latter is largely uncharacterized in microalgae. Here, we functionally...

Heterologous expression of flax PHOSPHOLIPID:DIACYLGLYCEROL CHOLINEPHOSPHOTRANSFERASE (PDCT) increases polyunsaturated fatty acid content in yeast and Arabidopsis seeds
Download2015
Weselake, Randall J., Mietkiewska, Elzbieta, Pan, Xue, Singer, Stacy D., Siloto, Rodrigo M. P., Wickramarathna, Aruna D.
Background Flax (Linum usitatissimum L.) is an agriculturally important crop with seed oil enriched in α-linolenic acid (18:3 cisΔ9, 12, 15; ALA). This polyunsaturated fatty acid (PUFA) is the major determinant for the quality of flax seed oil in food, nutraceuticals and industrial applications....

In vivo and in vitro evidence for biochemical coupling of reactions catalyzed by lysophosphatidylcholine acyltransferase and diacyglycerol acyltransferase
Download2015
Greer, Michael S., Pan, Xue, Weselake, Randall J., Chen, Guanqun, Zou, Jitao, Caldo, Kristian Mark P., Kazachkov, Michael
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...

Kinetic improvement of an algal diacylglycerol acyltransferase 1 via fusion with an acyl-CoA binding protein
Download2020-01-01
Xu, Yang, Caldo, Kristian Mark P., Falarz, Lucas, Jayawardhane, Kethmi, Chen, Guanqun
SUMMARY Microalgal oils in the form of triacylglycerols (TAGs) are broadly used as nutritional supplements and biofuels. Diacylglycerol acyltransferase (DGAT) catalyzes the final step of acyl-CoA-dependent biosynthesis of TAG and is considered a key target for manipulating oil production....

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...

β-Galactosidases and Fasciclin-like Arabinogalactan Proteins in Flax (Linum usitatissimum) Phloem Fibre Development
DownloadFall 2013
The phloem fibres of flax (Linum usitatissimum) have specialized, cellulose-rich secondary walls of the gelatinous type (G-type), which give the fibres remarkable strength. G-type walls are also found in tension wood of many trees. β-galactosidases (BGAL) and fasciclin-like arabinogalactan (FLA)...
