La savante organisation des plumes des oiseaux

Featured

Une étude à laquelle ont collaboré Athanasia Tzika et Michel Milinkovitch démontre comment des signaux génétiques et mécaniques se combinent pour permettre la formation d’un réseau organisé de plumes chez les oiseaux, leur permettant de voler. Les résultats ont été publiés le 21 février 2019 dans PLOS Biology.

An operon-like transcript has been identified in plants

Featured

Operons were thought to be absent in plants. The group of Michael Hothorn now reports the identification of an operon-like transcript in plants that allows for the concerted expression of a previously unknown cell-cycle regulator and a metabolic enzyme. This highly unusual transcript is conserved across the entire plant kingdom and is required for plant embryo development and growth. This study was published on February 8, 2019 in Nature Plants.

Jean-Claude Martinou wins the Lelio Orci Award 2018

Featured

The Lelio Orci Price has been attributed to Jean-Claude Martinou for his work on the control of mitochondrial organisation and physiology. His research group has made fundamental discoveries on the molecular mechanisms controlling the shape of mitochondria, their ability to import and to process metabolites, and to adapt to various metabolic situations.

The official award ceremony will take place on 15 February 2019 at the LS2 Annual Meeting 2019
