Herbicide resistance structures

[Giles Johnson]

I am currently preparing an undergrad lecture on the 
biochemistry and physiology of herbicides, including discussing 
issues of herbicide resistance (natural/engineered)  In order 
to keep the students awake I am looking for some pretty 
pictures e.g. structure of PSII w.t. vs resistant to DCMU.  Can 
anyone help?

Thanks, Giles
