structural domain

Monocotyledonous expression vector of double T-DNA was constructed with selective marker gene hyg ( hygromycin resistance) in one T-DNA structural domain and insect resistant gene in another T-DNA domain. Agrobacterium strain was transformed with this vector and used to transform embryonic callus of maize by co-culture.
