Clues into the evolutionary diversification of brassicas have emerged from the draft Chinese cabbage genome sequence1. Brassica crops include many agriculturally important vegetables, such as Chinese cabbage, pak choi, turnip, broccoli, cabbage and cauliflower, as well as various oilseed crops.
The sequencing focused on Chinese cabbage, Brassica rapa subspecies pekinensis, and was undertaken by the international Brassica rapa Genome Sequencing Project Consortium. The work was underpinned by the previously published genome sequence of the premier model of flowering plants, Arabidopsis thaliana. This species is related to B. rapa, with which it shared a common ancestor.
“Brassicas come in many shapes and sizes, and even individual species show considerable morphological variation. Genome information helps us understand the genetic basis of this diversity,” explains consortium member Hiroshi Abe of Japan’s RIKEN BioResource Center, one of the three biggest Arabidopsis stock centers in the world. “We developed genomic resources for Brassica rapa and contributed to the gene annotation in this project.”

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...

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...
