Resumen de Evolution of the bacterial organelle responsible for magnetotaxis

Christopher T. Lefèvre, Long Fei Wu

• There are few examples of protein- and lipid-bounded organelles in bacteria that are encoded by conserved gene clusters and lead to a specific function. The magnetosome chain represents one of these rare examples and is responsible for magnetotaxis in magnetotactic bacteria (MTB), a behavior thought to aid in finding their optimal growth conditions. The origin and evolution of the magnetotaxis is still a matter of debate. Recent breakthroughs in isolation, cultivation, single-cell separation, and whole-genome sequencing have generated abundant data that give new insights into the biodiversity and evolution of MTB.
