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.
在细菌中，只有少数由保守基因簇编码并具有特定功能的蛋白质和脂质结合细胞器的例子。磁小体链就是其中一个罕见的例子，它负责趋磁细菌（MTB）的趋磁行为，这种行为被认为有助于它们找到最佳的生长条件。趋磁行为的起源和进化仍然存在争议。最近在分离、培养、单细胞分离和全基因组测序方面的突破产生了大量的数据，为 MTB 的生物多样性和进化提供了新的见解。
