Expression of snowdrop lectin (GNA) in transgenic rice plants confers resistance to rice brown planthopper.
Snowdrop lectin (Galanthus nivalis agglutinin; GNA) has been shown previously to be toxic towards rice brown planthopper (Nilaparvata lugens; BPH) when administered in artificial diet. BPH feeds by phloem abstraction, and causes 'hopper burn', as well as being an important virus vector. To evaluate the potential of the gna gene to confer resistance towards BPH, transgenic rice (Oryza sativa L.)...
متن کاملStacking of antimicrobial genes in potato transgenic plants confers increased resistance to bacterial and fungal pathogens.
Solanum tuberosum plants were transformed with three genetic constructions expressing the Nicotiana tabacum AP24 osmotine, Phyllomedusa sauvagii dermaseptin and Gallus gallus lysozyme, and with a double-transgene construction expressing the AP24 and lysozyme sequences. Re-transformation of dermaseptin-transformed plants with the AP24/lysozyme construction allowed selection of plants simultaneou...
متن کاملTransgenic plants expressing ω-ACTX-Hv1a and snowdrop lectin (GNA) fusion protein show enhanced resistance to aphids
Recombinant fusion proteins containing arthropod toxins have been developed as a new class of biopesticides. The recombinant fusion protein Hv1a/GNA, containing the spider venom toxin ω-ACTX-Hv1a linked to snowdrop lectin (GNA) was shown to reduce survival of the peach-potato aphid Myzus persicae when delivered in artificial diet, with survival <10% after 8 days exposure to fusion protein at 1 ...
متن کاملLocalization and topogenesis studies of cytoplasmic and vacuolar homologs of the Galanthus nivalis agglutinin.
The Galanthus nivalis agglutinin (GNA) is synthesized as a preproprotein. To corroborate the role of the different targeting peptides in the topogenesis of GNA and related proteins, different constructs were made whereby both the complete original GNA gene and different truncated sequences were coupled to the enhanced green fluorescent protein (EGFP). In addition, a GNA ortholog from rice that ...
متن کاملExploring the Defensive Roles and Regulations of Gna Domain Containing Monocot Mannose Specific Lectins
Plants confront to various encounters involving diverse attackers amongst which aphids contribute to large amount of agricultural losses. GNA (Galanthus nivalis) domain containing monocot lectins (GNA-MLs) have received prominence as insecticidal candidates in pest management programs effective against hemipteran sap suckers. Present article provides an update on the effects and outcome of mole...
