Fall 2014
Quantitatively, nitrogen (N) has shown to be one of the most important nutrients for proper plant growth and development, and a key limiting factor in crop productivity. In the last 40 years, there has been a significant increase in the production of synthetic N-fertilizers, as well as an...

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 2014
Monoamine oxidase enzymes are largely involved in the catabolism of biogenic amines. Two forms of the enzyme are socumented to exist, monoamine oxidase type A and B. The B form (MAO-B) of the enzyme has been noted to possess a high affinity site for some imidazoline ligands. This site (the I2...

Characterization of a Type‐2 Diacylglycerol Acyltransferase from Haematococcus pluvialis Reveals Possible Allostery of the Recombinant Enzyme
Download2019-12-26
Nguyen, Trinh, Xu, Yang, Abdel-Hameed, Mona, Sorensen, John L., Singer, Stacy D., Chen, Guanqun
Haematococcus pluvialis is a green microalga used in the algal biotechnology industry that can accumulate considerable amounts of storage triacylglycerol (TAG) and astaxanthin, which is a high‐value carotenoid with strong antioxidant activity, under stress conditions. Diacylglycerol...

Characterization of Type-2 Diacylglycerol Acyltransferases in the Green Microalga Chromochloris zofingiensis
Download2018-12-13
Xu, Yang, Falarz, Lucas, Chen, Guanqun
Diacylglycerol acyltransferase (DGAT) catalyzes the last and committed step of the acyl-CoA-dependent TAG biosynthesis and thus is a key target for manipulating oil production in microalgae. The microalga Chromochloris zofingiensis can accumulate substantial amounts of triacylglycerol (TAG) and...

Down-Regulation of CELLULOSE SYNTHASE Expression in Arabidopsis Seeds as a Possible Means of Increasing Seed Oil and Protein Content, and Reducing Fibre Content
DownloadSpring 2017
Jayawardhane Rathnayaka,Kethmi N
Oleaginous seeds, with higher oil and protein content, have higher economic value in the seed oil industry. Meal resulting from the seed oil extraction process is a widely used protein source in animal feed. The reduction of the complex fibre component of seed tissues may direct more carbon into...

Engineering Arabidopsis long-chain acyl-CoA synthetase 9 variants with enhanced enzyme activity
Download2018-12-17
Xu, Yang, Caldo, Kristian Mark P., Holic, Roman, Mietkiewska, Elzbieta, Ozga, Jocelyn, Rizvi, Syed Masood, Chen, Guanqun, Weselake, Randall
Long-chain acyl-CoA synthetase (LACS, EC 6.2.1.3) catalyzes the ATP-dependent activation of free fatty acid to form acyl-CoA, which in turn serves as the major acyl donor for various lipid metabolic pathways. Increasing the size of acyl-CoA pool by enhancing LACS activity appears to be a useful...

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...
