New GFP request

Dear Mark,
	I thnk that you might have some problem expressing GFP in
Rhizobium.  Chromophore formation requires molecular oxygen.  E. coli
expressing GFP do not fluoresce when grown anaerobically.  Upon shift to
aerobic conditions, fluorescence slowly appears.  I don't know much about
Rhizobium, but I seem to remember from undergrad Biochemistry classes (at
UW-Madison!) that root nodules in legumes contain large amounts of oxygen
scavenging leghemoglobin protein.  Maybe you can culture your bugs
aerobically?
Sincerely,

Mike Moser                                            Tel: 206-543-6585
