The mannose-specific snowdrop lectin (Galanthus nivalis agglutinin: GNA), when fed to insects, binds to the gut epithelium and passes into the haemolymph. The ability of GNA to act as a carrier(More)
Three distinct digestive protease activities, with strongly alkaline pH optima, were identified in the gut of tomato moth (Lacanobia oleracea) larvae, and characterised using specific synthetic(More)
Transgenic rice plants expressing snowdrop lectin (Galanthus nivalis agglutinin; GNA) were screened for resistance to green leafhopper (Nephotettix virescens; GLH), a major homopteran pest of rice.(More)
Rice brown planthoppers (Nilaparvata lugens) were fed on artificial diet containing snowdrop lectin (Galanthus nivalis agglutinin; GNA), which has been shown to be toxic towards this insect pest. In(More)
Biolistic transformation was used to introduce genes encoding the insecticidal proteins snowdrop lectin (Galanthus nivalis agglutinin; GNA) and cry1Ac Bt toxin (δ-endotoxin from Bacillus(More)
