Fig. 5From: Activation of metabolic and stress responses during subtoxic expression of the type I toxin hok in Erwinia amylovoraEffect of hok induction on ATP biosynthesis in E. amylovora. Both extracellular and intracellular levels of ATP were simultaneously quantified using a luciferase reporter system. Results represent the means of three biological replications and error bars indicate the standard deviation. Different letters indicate significant differences (P < 0.05) using Tukey’s HSD test. The assays were done twice with similar resultsBack to article page
