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...

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...

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

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...

Shah, Saleh, Xu, Yang, Ramakrishnan, Geetha, Caldo, Kristian Mark P., Chen, Guanqun, Ozga, Jocelyn, Greer, Michael S., Lemieux, M. Joanne, Wu, Limin, Weselake, Randall J.
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...

Physaria fendleri and Ricinus communis LCAT-like phospholipases selectively cleave hydroxy acyl chains from phosphatidylcholine

Xu, Yang, Caldo, Kristian Mark P., Singer, Stacy D., Mietkiewska, Elzbieta, Greer, Michael S., Tian, Bo, Dyer, John M., Smith, Mark, Zhou, Xue-Rong, Qiu, Xiao, Weselake, Randall J., Chen, Guanqun
Producing hydroxy fatty acids (HFAs) in transgenic crops represents a promising strategy to meet our demands for specialized plant oils with industrial applications. The expression of Ricinus communis (castor) OLEATE 12-HYDROXYLASE (RcFAH12) in Arabidopsis has resulted in only...

Oxygen deprivation (hypoxia and anoxia) is an environmental stress affecting plants worldwide in many natural and man-made ecosystems. Aquaporins exhibit multiple physiological functions in challenging environments. The central role of aquaporins in plant water relations has been widely...
