Recombinant constructs useful for reducing the expression of at least one
target nucleic acid fragment of interest and any substantially similar
endogenous nucleic acid fragment of interest are disclosed. In
particular, a recombinant construct comprising at least one nucleic acid
of interest is inserted between two convergent promoters. A plant or
plant organ stably transformed with this construct will have a reduction
in expression of the target nucleic acid fragments of interest.
