SCIENCE – PatB is a transcriptional activator required for nitrogen fixation and cell differentiation in cyanobacteria.

Under nitrogen-limiting conditions, the filamentous cyanobacterium Nostoc PCC7120 differentiates nitrogen-fixing heterocysts at semi-regular intervals along filaments generating a periodic pattern of two distinct cell types. Heterocysts are micro-oxic cells that host the oxygen-sensitive nitrogenase allowing two antagonistic activities to take place simultaneously. Although several factors required to control the differentiation process are known, the molecular […]

COM – La vidéo d’animation illustrant les recherches menées au LCB est en ligne !

Lors de la refonte du site du laboratoire, une groupe de travail associant les étudiants du LCB a mené une réflexion sur la création d’une vidéo de médiation scientifique qui illustrerait les recherches menées dans nos locaux. Cette vidéo est a présent disponible et vous pouvez la visualiser ci-dessous. Compte tenu du public auquel elle […]
