In order to achieve saturating transposon mutagenesis of the genome of plant pathogenic strains of Pseudomonas syringae we needed to improve plasmid conjugation frequency. Manipulation of the growth stage of donor and recipient cells allowed the required increase in frequency and facilitated conjugation of otherwise recalcitrant strains.
