摘要
A broad range of organisms have evolved abilities to exploit the Earth’s magnetic field for orientation and navigation-a behavior known as magnetoreception(Nordmann et al.,2017).Magnetotactic bacteria(MTB),diverse microbes with a patchy distribution across the bacterial tree of life,are the best known and most extensively studied magnetosensitive microorganisms.In order to efficiently achieve magnetotactic behavior,MTB biomineralize intracellular chain-arranged magnetic single-domain crystals of magnetite(Fe_(3)O_(4))and/or greigite(Fe_(3)S_(4))called magnetosomes,which are unique prokaryotic organelles that confer a magnetic moment to the cell and act as an internal compass needle(Bazylinski and Frankel,2004).
