Dear newsgroup
   Does anyone know the selectable marker for the plasmid pFQ148 
(genbank L41344) which contains genes nifV, nifH, nifD, nifK and niE. 
The work was done by specq. A. and Normand, P. (unpublished, 1996). If 
the authors read this, please let me know.  All help will be duly 
acknowledged.
