Abstract

The bacterial flagellum is beneficial in most cases but it can become a burden when the energy source is low because it is very costly to assemble and energize for motility. Recent electron cryo-tomography and real-time fluorescence microscopy studies suggest that bacteria can remove their flagella under starvation in a programmed way.

摘要

细菌鞭毛在大多数情况下是有益的，但当能量来源不足时，它可能会成为一种负担，因为组装和驱动鞭毛以实现运动的成本非常高。最近的电子冷冻断层扫描和实时荧光显微镜研究表明，细菌在饥饿状态下可以以一种程序化的方式去除它们的鞭毛。
