Abstract
A subgenomic promoter of a positive strand RNA virus is disclosed which directs the amplified expression of a structural gene in plant tissue. The core region and an upstream activating domain of the subgenomic promoter are identified. This promoter can be utilized in a modified virus, or in an appropriate engineered recombinant DNA derivative which may be chromosomally integrated or maintained as an episome in transformed cells.
