Nucleic acid molecules and methods for the expression of foreign genes in plants

A nucleic acid molecule for the expression of foreign genes in plants, right border sequence of T-DNA derived sequences of Agrobacterium (RB), expression promoter sequence that functions in said plant, of the gene encoding the 2b protein one part or all of a sequence corresponding to the RNA2 genome of cucumber mosaic virus, which is substituted in the foreign gene, and Agrobacterium T-DNA sequences derived from the left border sequence (LB) in this order.
