Very interesting story about the #nitroplast, a potential new organelle resulting from #symbiosis between nitrogen-fixing bacteria and the #microalgae *Braarudosphaera bigelowii* based on subcellular imaging and proteomic data.
Possibly a new model to study the evolutionary transition from #endosymbiont to organelle.
