Functional analysis of sugar beet resistance genesheadline bar Functional analysis of sugar beet resistance genes **** **** picture showing normal (control) and transformed with BvSTI gene for both larvae and pupae  To broaden the scope of potential target insects that utilize serine proteases for digestion, we cloned sugar beet root genes that are associated with root defense responses.One of the genes,BvSTI, codes for a serine proteinase inhibitor which we cloned and reconstructed for over-expression in a heterologous plant system.This figure shows tobacco hornworm (M. sexta) larvae (left) and pupae (right) after feeding onN. benthamianatransformed with theBvSTIgene or on normal, untransformed control plants.Our results revealed a substantial reduction in larval and pupal sizesthat is mediated by the production of theBvSTIgene product in tobacco.
