A New Resource for Advanced Biofuels Research

24.06.2014

Researchers at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) have unveiled the first glycosyltransferase clone collection specifically targeted for the study of the biosynthesis of plant cell walls.

The idea behind what is being called “the JBEI GT Collection” is to provide a functional genomic resource for researchers seeking to extract the sugars in plant biomass and synthesize them into clean, green and renewable transportation fuels.

Glycosyltransferases (GTs) are enzymes that catalyze the connection of simple monosaccharide sugars into the complex polysaccharide sugars that are essential to a wide range of plant cell structures and processes. While it is known that plants have evolved large families of GTs, the chemical nature of these enzymes is such that the specific functions of most GTs remain largely unknown. This is a major drawback for bioenergy research where the goal is to modify plant biomass for maximum fuel yields.

To address this problem, especially as it pertains to cell wall biosynthesis, a large team of JBEI researchers, led by Joshua Heazlewood, director of JBEI’s Plant Systems Biology program, has cloned and verified a clone library consisting of 403 Arabidopsis GTs and 96 rice GTs. In plant biology, Arabidopsis is the reference plant for species like poplar, and rice the reference plant for grasses.

“Using the unique infrastructure and resources at JBEI, we have provided a collection of high quality GT clones, all of which have been verified by sequencing and are available in easy to use cassettes,” Heazelwood says. “We’re making this entire collection available to the plant research community and expect it to drive our basic understanding of GTs and enable the manipulation of cell walls.”

In addition to the clones for Arabidopsis and rice GTs, Heazlewood and his collaborators at JBEI also created a set of highly efficient particle bombardment plasmids – pBullets – which are plasmids shot into a cell to mark the location of targeted proteins. The JBEI pBullets are constructed with markers for the plant endomembrane system, the collection of membranes that separates a cell’s functional and structural compartments.

“Our pBullet vector series is custom designed for efficient bombardment,” Heazlewood says. “Researchers generally use large unwieldy plasmids that perform badly when it comes to localizing proteins.”

While the 403 Arabidopsis clones represent approximately 88-percent of the defined Arabidopsis GTs, the 96 rice clones represent only 15-percent of the defined rice GTs. JBEI researchers are now working to expand this. Both the JBEI GT Collection and pBullet vector series are available to the research community through various outlets.

Heazlewood and his collaborators have published a paper on the JBEI GT Collection in The Plant Journal. The paper is titled “The Plant Glycosyltransferase Clone Collection for Functional Genomics.” Co-authors were Jeemeng Lao, Ai Oikawa, Jennifer Bromley, Peter McInerney, Anongpat Suttangkakul, Andreia Smith-Moritz, Hector Plahar, Tsan-Yu Chiu, Susana González Fernández-Niño, Berit Ebert, Fan Yang, Katy Christiansen, Sara Hansen, Solomon Stonebloom, Paul  Adams, Pamela Ronald, Nathan Hillson, Masood Hadi, Miguel Vega-Sánchez, Dominique Loqué and Henrik Scheller.

This research was funded by the U.S. Department of Energy’s Office of Science.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
