To better understand the complex processes involved in wood formation, researchers have developed a new method to study genetic regulatory mechanisms in poplar, a potential bioenergy feedstock (shown here).

To begin to understand the complex genetic interactions that control poplar growth, a potential bioenergy crop, researchers developed a robust high-throughput pipeline for studying the hierarchy of genetic regulation of wood formation using tissue-specific single cells known as protoplasts.

The Impact

This approach will be particularly useful in studying complex processes in plant species that lack mutants and stable transformation systems. It also can be used to improve forest tree productivity with more precise genetic approaches.

Summary

Wood is an important renewable material for bioenergy and other industrial products, but its formation, a complex process regulated at many levels, is poorly understood. Such processes often involve interactions between regulatory genes known as transcription factors (TFs) and their direct DNA targets. These TF-DNA interactions constitute a regulatory hierarchy.

The new method for isolating protoplasts from the wood-forming stem differentiating xylem tissues of poplar was developed by researchers at North Carolina State University with funding from the U.S. Department of Energy Genomic Science program. The team used the method to study the expression of a specific poplar TF affecting wood formation.

By integrating this novel system with computational approaches, a hierarchical layer of genes was inferred that was functionally validated in the wood-forming stem differentiating xylem. The new approach aids understanding hierarchical gene regulatory networks directed by TFs in poplar and other plant species where mutants are not available.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
