Conserved activation mechanism for plant membrane receptors uncovered

Featured

In collaboration with researchers from Oslo University, Michael Hothorn’s team has analyzed the activation mechanism of two plant membrane receptor kinases, a steroid hormone receptor controlling plant growth, and a peptide hormone receptor controlling leave shedding. Both receptors rely on the same helper protein for activation. The helper uses two different areas to contact the respective receptor and to specifically read out the chemically diverse ligands. The researchers understand the underlying mechanisms in sufficient detail to lego-build functional receptor chimera that now allow to induce leave shedding by applying the plant steroid hormone normally triggering growth. These findings were published on March 12, 2018 in PNAS.

Sardines take us to the sources of biodiversity in the Amazon River

Featured

The team of Juan Montoya has integrated a range of factors into a single statistical model to study the genesis of genetic diversity within a typical Amazonian species. This new approach, adaptable to any species, enables to assess the impact of present and future human large-scale alterations. The study was published on December 20, 2017 in PLoS ONE.
