Abstract
Chimeric regulatory regions and gene cassettes based upon Agrobacterium tumefaciens opine sythase genes are provided for expressing foreign genes in plants. Various upstream activating sequences from opine synthase genes like the mannopine synthase and the octopine synthase genes are operably linked with promoters (or promoters plus activating sequences), both of which are then operably linked to the foreign gene. These regions and cassettes permit expression levels and patterns that could not be obtained previously.
