A plasmid expressing mupLMNOPVCFU+macpE together with a derivative of the producer P. fluorescens strain NCIMB10586 lacking the mup cluster allowed conversion of PA-B to PA-A . MupN converts apo-mAcpE to holo-form while MupM is a mupirocin-resistant isoleucyl tRNA synthase, preventing self-poisoning. (birmingham.ac.uk)
Surprisingly, the expression plasmid failed to allow the closely related P. fluorescens strain SBW25 to convert PA-B to PA-A. (birmingham.ac.uk)

D) represent the proportional changes in population abundance of P. fluorescens SBW25 when grown alone versus in the presence of another competitor strain. (free.fr)
The predictor variable is phylogenetic distance between Pseudomonasfluorescens SBW25 and its paired target strain, with more negative being phylogenetically close to 1.00 being the most distant strain. (free.fr)
The response variable is change in D along the salinity gradient for each replicate cline (i.e. the rate at which effects of biotic interactions on the abundance of the focal strain SBW25 change with elevated salinity). (free.fr)
