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(More)
The lectin binding pattern of muscular microvessels in chick, quail and chick/quail chimeras was analysed. Paraffin wax sections of muscles from embryonic and adult animals were used. The biotin-labelled lectins were detected by avidin-alkaline phosphatase complex. The following lectins bound to muscular microvessels including arterioles, capillaries and(More)
The distribution pattern of glycoconjugates in human eccrine sweat glands has been studied by the binding of newly discovered lectins and by antibodies against a chondroitin sulphate proteoglycan and chondroitin sulphate glycosaminoglycans. Mannose-specific lectins labelled large intracellular granules, part of which could be extended cisternae of the(More)
A sensitive enzyme-immunoassay was developed to quantify the tulip lectin and used to follow its distribution during the life cycle of tulips cv. Attila. The tulip lectin is predominantly located in the bulbs. At planting time the absolute lectin concentration is approximately the same in all bulb scales. However, as the shoot grows and the plant turns on(More)
A sensitive immunosorbent assay was developed to quantify the lectin in different tissues ofGalanthus nivalis (snowdrop) andNarcissus cv. Carlton (daffodil) and follow the distribution of the lectin during the life cycle of the plants. The lectin in snowdrops and daffodils occurs in almost all plant tissues. Moreover, in many tissues the lectin is the most(More)
