Abstract A synthetic gene, mwti1b, coding for a winged bean trypsin inhibitor WTI-1B, has been introduced and expressed in rice plants, Oryza sativa. Protein extracts from transgenic rice plants expressing the trypsin inhibitor inhibited the gut proteases of larvae of the serious insect pest, the rice stem borer, Chilo suppressalis (Lepidoptera: Pyralidae) in vitro. The growth of larvae reared on transgenic rice plants expressing WTI-1B at more than 1 ng/10 μg total protein was significantly retarded compared to that on non-transgenic control plants.
