inhibitors of RNA & protein synthesis.

[Chris Town]

I would like to inhibit new gene expression in some experiments designed to 
investigate the inducibility of a hormone conjugation system. 
I would appreciate advice of the effectivenss of traditional eukaryotic 
inhibitors such as actinomycin D, alpha-amanitin, cycloheximide.
Test material will be seedlings in suspension.
Do these compounds work? What concentrations? How effective?
References?

I'll summarize and post any relies that don't appear directly on the net.

Thank y'all for your time.
Happy New Year.
