Accumulation of PolyP in P. fluorescens Pf0-1ΔrecA carrying pHERDiiv8 or the vector (pHERD). Induction of iiv8 transcription from the PBAD promoter in pHERDiiv8 resulted in PolyP accumulation that was approximately 25% of that obtained with the uninduced vector control (P < 0.01). The y axis shows PolyP accumulation as a percentage of that in uninduced Pf0-1 carrying the pHERD26 vector after normalization for cell number. Data are the average of at least three independent experiments. Error bars show the standard deviations.
