New interdisciplinary consortium at AU will study membrane-less organelles

Associate Professor Magnus Kjærgaard participates in a new consortium, BOUNDLESS, headed by Associate Professor Frans Mulder and funded by the Interdisciplinary Synergy Programme of the Novo Nordisk Foundation. With the grant of DKK 14.4 M, the consortium will study how membrane-less organelles control key biological processes.

The LysM receptors on the outside of root cells from the legume <em>Lotus japonicus</em> determine whether harmful or beneficial microbes from the soil are recognised by the plant. The structure of the symbiotic receptor LYK3 and comparison with the immune chitin receptor CERK6 helped the researchers map important elements for recognition (figure: Kasper Røjkjær Andersen)

Top 5 science result in 2020: Signal molecules are the key to less use of fertilisers

Results published in Science from Aarhus University describe how legumes pick up special signalling molecules to distinguish between harmful and beneficial microbes. These results have been nominated by the Danish technical news journal “Ingeniøren” (the Engineer) as being among the five most important results in Denmark in 2020.

RNA polymerase II (RNAPII) initiates transcription at a multitude of positions in the human genome. However, only a fraction of these sites is associated with genes that give rise to functional RNA. The ‘Integrator’ complex by default terminates RNAPII shortly after its initiation (top), unless specific gene-defining elements are present allowing for transition to productive elongation (bottom). In the latter case, transcription is typically terminated by the ‘Cleavage & Polyadenylation’ Complex that recognizes specific ‘terminator’ sequence elements in the genome (bottom, red box). In the former case the produced short RNA is by default rapidly degraded by the RNA exosome, whereas snRNAs constitute a special case that avoids degradation. Figure: Søren Lykkke-Andersen.

Integrator: A guardian of the human transcriptome

In a joint collaboration, Danish and German researchers have characterized a cellular activity that protects our cells from potentially toxic by-products of gene expression. This activity is central for the ability of multicellular organisms to uphold a robust evolutionary ‘reservoir’ of gene products.
