Freund oder Feind? – Die zwei Gesichter von Photorhabdus luminescens

Abstract

Photorhabdus luminescens is an enteric bacterium with two faces: on the one hand these bacteria live in symbiosis with soil nematodes, on the other hand they are highly pathogenic for insects. The population is also phenotypically heterogeneous: one part lives in symbiosis with nematodes, the other part symbiotically interacts with plants. Cell-cell communication, inter-kingdom signaling, and other gene regulation processes are behind the complex decision of being friend or foe.
