Abstract
Methods and materials are provided to isolate the coat protein genes from maize chlorotic dwarf virus. One or more of these genes (MCDV-CP.sub.1, MCDV-CP.sub.2 or MCDV-CP.sub.3) is then incorporated in an expression cassette designed for suitable expression in a plant cell system. The resulting transformation vector is then introduced into maize to provide cross-protection to MCDV or related viral infections.
