- My understanding is that most people use a modified Agro plasmid
- (acutually a binary plasmid system is used) that has the opine
- synthase gene replaced with an antibiotic resistance (eg. Kan^R)
- gene. Is there any reason not to use this in your system?
- Incidentaly, Agro only introduces a part of the Ti plasmid (the
- T-DNA) into the host plant. In the wild the bacterium stays outside
- and feeds off the opines that are produced by the transformed plant.
- Hope this helps.
