Conteúdo: | The range of sap-sucking insect pests to which GNA, (the mannose specific lectin from snowdrops (Galanthus nivalis)) has been shown to be insecticidal in artificial diets has been extended to include the peach potato aphid (Myzus persicae). A gene construct for constitutive expression of GNA from the CaMV35S gene promoter has been introduced into tobacco plants. A transgenic tobacco line which expresses high levels of GNA has been shown to have enhanced resistance to M.persicae in leafdisc and whole plant bioassays, demonstranting the potential for extending transgenic plant technology to the control of sap-sucking insect pests.
