The study also shows that the Podospora genome contains a large, highly specialised set of genes potentially involved in the breakdown of complex carbon sources, which may have potential use in biotechnology applications.
P. anserina is a dung-inhabiting, saprophytic fungus used to study areas of eukaryotic and fungal biology, including ageing and sexual development. Eric Espagne, Olivier Lespinet and Fabienne Malagnac from the Institute of Genetics and Microbiology in Paris and a team of researchers from France and The Netherlands used a whole genome shotgun and assembly approach to produce a 10X draft sequence of the fungus.
The researchers found evidence that P. anserina has undergone dynamic evolution since it diverged from its close relative N. crassa. They found evidence of extensive gene loss and gene shuffling, as well as substantial gene duplication. In addition, the transcription machinery of P. anserina produced a large number of RNAs that could potentially have regulatory roles. Further investigation of these non-conventional transcripts is required and could lead to the discovery of novel regulatory mechanisms, specifically during mycelium growth or accompanying the differentiation of the multicellular fructification produced during sexual reproduction.
The research team also discovered that P. anserina contains a large array of genes that may allow the fungus to use the natural carbon sources found wherever it grows. For example, the fungus carries genes potentially involved in the breakdown of the plant polymers cellulose and lignin, which may have future applications in biotechnology.
Espagne concludes: “As for other saprophytic fungi, the P. anserina genome sequence has opened new avenues in the comprehensive study of a variety of biological processes … It also demonstrates how P. anserina is well adapted at the genome level to its natural environment, which was confirmed by the analysis of growth profiles. This result emphasizes the necessity to study several less well-tracked organisms in addition to those well known in the scientific community, as these may yield unexpected new insights into biological phenomena of general interest.”

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

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...
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...
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...
