Physaria fendleri and Ricinus communis LCAT-like phospholipases selectively cleave hydroxy acyl chains from phosphatidylcholine
Download2020-10-27
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...

Jayawardhane, Kethmi N., Singer, Stacy D., Weselake, Randall J., Chen, Guanqun
Acyl‐lipids such as intracellular phospholipids, galactolipids, sphingolipids, and surface lipids play a crucial role in plant cells by serving as major components of cellular membranes, seed storage oils, and extracellular lipids such as cutin and suberin. Plant lipids are also widely used to...

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...

Seed-specific down-regulation of Arabidopsis CELLULOSE SYNTHASE 1 or 9 reduces seed cellulose content and differentially affects carbon partitioning
Download2020-04-20
Jayawardhane, Kethmi N., Singer, Stacy D., Ozga, Jocelyn A., Rizvi, Syed Masood, Weselake, Randall J., Chen, Guanqun
Key message Seed-specific down-regulation of AtCESA1 and AtCESA9, which encode cellulose synthase subunits, differentially affects seed storage compound accumulation in Arabidopsis. High amounts of cellulose can negatively affect crop seed quality, and, therefore, diverting carbon partitioning...

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...

Singer, Stacy D., Jayawardhane, Kethmi N., Jiao, Chen, Weselake, Randall J., Chen, Guanqun
ABSTRACT Seed fatty acids (FAs) and triacylglycerol (TAG) contribute to many functions in plants, and seed lipids have broad food, feed and industrial applications. As a result, an enormous amount of attention has been dedicated towards uncovering the regulatory cascade responsible for the fine44...

The potential of genome editing for improving seed oil content and fatty acid composition in oilseed crops
Download2020-08-27
Subedi, Udaya, Jayawardhane, Kethmi N., Pan, Xue, Ozga, Jocelyn, Chen, Guanqun, Foroud, Nora A., Singer, Stacy D.
A continuous rise in demand for vegetable oils, which comprise mainly the storage lipid triacylglycerol, is fueling a surge in research efforts to increase seed oil content and improve fatty acid composition in oilseed crops. Progress in this area has been achieved using both conventional...

Uncovering the Molecular Mechanisms behind Triacylglycerol Biosynthesis in Flaxseed (Linum usitatissimum L.)
DownloadFall 2015
Flax (Linum usitatissimum L.) seed oil contains approximately 45%-65% of α-linolenic acid (ALA) and 15-29 % of linoleic acid (LA), and is one of the richest natural sources of these polyunsaturated fatty acids (PUFAs). Due to its high amounts of PUFAs, especially ALA, flax oil has a number of...
