How An Organelle Evolves
Organelles in cells were originally often independent cells, which were incorporated by host cells and lost their independence in the course of evolution. A team of biologists headed by Professor […]

New Insight Into Chloroplast Evolution
One of the most momentous events in the history of life involved endosymbiosis — a process by which one organism engulfed another and, instead of ingesting it, incorporated its DNA […]

The Nitroplast Revealed: A Nitrogen-fixing Organelle In A Marine Alga
A nitrogen-fixing bacterial endosymbiont of marine algae is evolving into a nitrogen-fixing organelle, or nitroplast, according to a new study, thereby expanding a function that was thought to be exclusively […]

The First Known Nitrogen-fixing Organelle
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as […]
