ura3/foa equivalent for p. aeruginosa

[Christophe Dessimoz]

hi,

i'm looking for a selectable marker for a plasmid to be transformed
into p. aeruginosa (gram negative bacterium) that has similar features
as the ura3 marker in yeasts, i.e. useful for positive and negative
(using 5-foa) selection.

any idea?

thanks,
christophe
