where can I get any plasmid with aadA as selective marker gene? - i might offer some money (Oct/11/2006 )

who can provide me any plasmid with aadA as selective marker gene? I would use it to construct a chloroplast transformation vector. I would offer some money for it if necessary. My email: city0537@yahoo.com

Your best bet is to ask an author of a paper using the gene. Here is one example:

A google search of 'aacA spectinomycin' brought up dozens.
