Fig. 6From: Systematic identification of a panel of strong promoter regions from Listeria monocytogenes for fine-tuning gene expressionVisualization of EGFP expression controlled by P29 in zebrafish embryos infected by Lm EGD-e △actA/inlB under fluorescence microscope. A Lm EGD-e △actA/inlB (control); B Lm EGD-e △actA/inlB (pERL3-29). The zebrafish fertilized eggs were microinjected with bacteria and observed after 26 h. EGFP fluorescence was detected under fluorescence microscopeBack to article page
