Investigation of plant-bacteria interactions requires quantification ofin plantabacterial titers by means of cumbersome and time-consuming colony-counting assays. Here, we devised a broadly applicable tool for bioluminescence-based quantitative and spatial detection of bacteria in plants. We developed vectors that enable Tn7transposon-mediated integration of theluxCDABEluciferase operon into a specific genomic location found ubiquitously across bacterial phyla. These vectors allowed for the generation of bioluminescent transformants of various plant pathogenic bacteria from the generaPseudomonas,Rhizobium(Agrobacterium), andRalstonia. Direct luminescence measurements of plant tissues inoculated with bioluminescentPseudomonas syringaepv.tomatoDC3000 (Pto-lux) reported bacterial titers as accurately as conventional colony-counting assays inArabidopsis thaliana,Solanum lycopersicum,Nicotiana benthamiana, andMarchantia polymorpha. We further showed the usefulness of our vectors in converting previously generatedPtoderivatives to isogenic bioluminescent strains. Importantly, quantitative bioluminescence assays using thesePto-lux strains accurately reported the effects of plant immunity and bacterial effectors on bacterial growth, with a dynamic range of four orders of magnitude. Moreover, macroscopic bioluminescence imaging illuminated the spatial patterns ofPto-lux growth in/on inoculated plant tissues. In conclusion, our vectors offer untapped opportunities to develop bioluminescence-based assays for a variety of plant-bacteria interactions.
