Although plasmids are ubiquitous amongst phytosphere pseudomonads, the advantage and costs of plasmids for the bacterial host remain unclear. The application of single-cell Raman spectral analysis to plasmid–bacterial systems under different environmental conditions offers a new means of determining the impact of plasmids on host cell physiology, metabolic status, and response to stress.
