phloroglucinol type herbicides

[Judith Gallant]

Dear photosynthesis people,

I'm a student in biophysics, studying PS II.  I read an 1995 article lately
about products which interest me greatly.  They said that as
N-octyl-3-nitro-2,4,6-trihydroxybenzamide (PNO8), ... some phloroglucinol
derivatives also induce D1 degradation and their capabilities showed a good
correlation with their activities as PS II inhibitors (data not show)  ...
There was no references.   I really need to know which phoroglucinol
derivates degrate D1, and which do not.  Does anybody know?  Is their new
published data about this?

Thank you in advance

Judith
