How plant mitochondria make their own proteins 🌱🔬
A new study published in @natcomms.nature.com reveals the structure of the cauliflower mitoribosome and a unique RsgA mechanism that blocks premature translation.

NDUFAF3 is Involved in the Assembly of the Q/P Modules of Respiratory Complex I in the Green Microalga Chlamydomonas reinhardtii The mitochondrial NADH:ubiquinone oxidoreductase, or complex I, is composed of a hydrophobic arm comprising the P module and a hydrophilic arm comprising the N and Q modules. The assembly of complex ...

Colonisation des plantes : les pieds sur terre Il y a environ 500 millions d’années, les plantes aquatiques colonisaient la terre ferme, entraînant à leur suite les vertébrés herbivores. Que connaît-on des mécanismes à l’origine de cette sortie de...

#Podcast du jour. Il y a env. 500 Ma, les plantes aquatiques colonisaient la terre. Que connaît-on des mécanismes à l’origine de cette sortie des eaux ? Quelles ont été les adaptations nécessaires ? tinyurl.com/2a62nz3y avec Pierre-Marc Delaux, @huguesrenault.bsky.social & Christine Strullu-Derrien

In-cell architecture of the mitochondrial respiratory chain Mitochondria regenerate adenosine triphosphate (ATP) through oxidative phosphorylation. This process is carried out by five membrane-bound complexes collectively known as the respiratory chain, workin...

In a new Science study, cryo–electron tomography captures the in-cell architecture of the mitochondrial respiratory chain, illuminating how the coordinated action of molecular machines drives life’s fundamental energy conversion.
