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.”

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
