Une étudiante en biologie sauve Pâris et Hélène d’une condamnation

Mis en avant

Anne Morel, étudiante en Master de biologie, a remporté le Concours d’art oratoire de l’UNIGE faisant le procès d’Hélène et de Pâris, dont l’amour et la fuite furent aux sources de la mythique guerre de Troie. L’étudiante a soulevé plusieurs incohérences dans la façon dont le mythe est raconté, sauvant ainsi les deux héros d’une condamnation.

Conserved activation mechanism for plant membrane receptors uncovered

Mis en avant

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.
