From macro to micro: a combined bioluminescence-fluorescence approach to monitor bacterial localization.

ABSTRACT: Bacterial bioluminescence is widely used to study the spatiotemporal dynamics of bacterial populations and gene expression in vivo at a population level but cannot easily be used to study bacterial activity at the level of individual cells. In this study, we describe the development of a new library of mini-Tn7-lux and lux::eyfp reporter constructs that provide a wide range of lux expression levels, and which combine the advantages of both bacterial bioluminescence and fluorescent proteins to bridge the gap between macro- and micro-scale imaging techniques. We demonstrate that a dual bioluminescence-fluorescence approach using the lux operon and eYFP can be used to monitor bacterial movement in plants both macro- and microscopically and demonstrate that Pseudomonas syringae pv phaseolicola
