Figure 1 | Schematic diagram showing the experimental procedure. Experiment 1 (Expt1): Antibiotic experiment and physiological monitoring of A. erythraea ; Experiment 2 (Expt2): Gut dissection and omics analysis of A. erythraea on different diets; Experiment 3 (Expt3): Cell death and proliferation staining ofA. erythraea . Cell death was labelled by terminal deoxynucleotidyl transferase biotin-dUTP nick end labelling (TUNEL), and cell proliferation was measured by 5-Ethynyl-2-deoxyuridine (EdU) incorporation.
