Who knows a very strong Chlamy promotor

[Mathias Zeidler]

Hi,
I am working on the moss Ceratodon and I am not lucky with higher 
plant promotors for very strong expression (35S does not work very 
well). I want to try some promotors from primitive organisms, 
especially algea. If somone knows a very strong Chlamy promotor, 
I would be very thankful for a message and if possible a source for 
the plasmids so that I can reclone it into my constructs.
Thank you very much in advance,
Mathias Zeidler
