The present inventors isolated a plurality of promoters having various expression characteristics from a monocot and by connecting the OsWRKY45 gene downstream of each and reintroducing to the monocot (rice) a rice strain was produced having both complex disease resistance and favorable agronomic characteristics. As a result the present inventors succeeded in producing a transformed plant body having both complex disease resistance and agronomic characteristics by causing the expression of OsWRKY45 using the upstream sequence of EF1a and OsUbi7 as promoters.
