Microbiota-Dependent and -Independent Production of l- Dopa in the Gut of Daphnia magna

Abstract

Neurotransmitters are commonly implicated in host-microbiome communication, yet the molecular mechanisms of this communication remain largely elusive. We present novel evidence linking the gut microbiome to host development and growth via neurotransmitter l- Dopa in Daphnia , the established model species in ecology and evolution.
