  Dear netters; I want to express a lethal gene in an antisense orientation in
Arabidopsis plants.  As I cannot express this antisense with 35S promoter, I
am looking for another promoter.  I would like the promoter to be
developmentally regulated ,and highly expressed during later stages of leaf
expansion (but not during senescence).
    This promoter should not be activated upon tissue culture stress often
associated during plant transformation.
  I think one of the promoters for chalcone synthase may serve this purpose ,
 but I am not sure.   I appreciate any other suggestions, and gratefully
acknowledge the lab who send me such Arabidopsis promoter.
