Bacteria developed many different ways to orient themselves in the environment. Magnetoreception with following motility along Earth's magnetic field lines and photoreception with subsequent positive or negative phototaxis allow bacteria to optimally position themselves for survival and growth. Some bacteria show both magnetotactic and photoresponsive behaviour and additionally live in a multicellular organism adding another layer of complexity. A novel study by Qian and colleagues visualized different species of multicellular magnetotactic bacteria and shed light on their reproductive as well as photoresponsive behaviour. This study paves the way towards understanding the evolutionary advantage of multicellular lifestyle of prokaryotes.

其中一些具有全部功能：一种细菌具有多细胞性，趋磁性和光动力学。

细菌开发出许多不同的方式来适应环境。沿着地球磁场线具有随后的运动的磁感受和随后的正或负趋光性的光感受使细菌能够最佳地定位自身，以生存和生长。一些细菌同时表现出趋磁行为和光响应行为，并且还生活在多细胞生物中，这又增加了另一层复杂性。钱和同事的一项新研究可视化了不同种类的多细胞趋磁细菌，并阐明了它们的生殖以及光响应行为。这项研究为了解原核生物多细胞生活方式的进化优势铺平了道路。
