BACKGROUND
Cloning of the Euonymus lectin led to the discovery of a novel domain that also occurs in some stress-induced plant proteins. The distribution and the diversity of proteins with an Euonymus lectin (EUL) domain were investigated using detailed analysis of sequences in publicly accessible
daughterless-abo-like (dal) is a maternal-effect semilethal mutation in Drosophila. The nuclear divisions of embryos derived from homozygous dal females are normal through nuclear cycle 10. However, during nuclear cycles 11, 12 and 13, a total of about half of the nuclei in each embryo either fail
Precipitation induced by different lectins has been studied in the presence of some aminoacids. It was shown that precipitates formed by lectins from Ricinus communis (RCA1), Canavalia ensiformis (Con A), Euonymus europaeus (Eel) in the presence of appropriate carbohydrate-containing molecules
Two structurally different chitin-binding proteins were isolated from bark and leaves of the spindle tree (Euonymus europaeus L.). Both the small hevein-like chitin-binding protein (Ee-CBP) and the classical class-I chitinase (Ee-chitinase) possess antifungal properties, Ee-CBP being far more potent
Euonymus europaeus lectin (EEL) is a carbohydrate-binding protein derived from the fruit of the European spindle tree. EEL was first identified for its erythrocyte agglutinating properties and specificity for B and H blood groups. However, a detailed molecular picture of the structural basis of
Cell-surface carbohydrates of Entamoeba invadens trophozoites were analyzed using (a) a panel of highly purified lectins specific for molecules containing N-acetylglucosamine or sialic acid, N-acetylgalactosamine, galactose, mannose-like residues, and fucose; (b) Escherichia coli K-12 with
Genetic evidence has shown the presence of a common spindle pole organiser in Physarum amoebae and plasmodia. But the typical centrosome and mitosis observed in amoebae are replaced in plasmodia by an intranuclear mitosis devoid of any structurally defined organelle. The fate of gamma-tubulin and of
BACKGROUND
The aim of our study was to evaluate the possibility of embryonic or somatic cell haploidization after fusion with intact or enucleated immature oocytes which were subsequently cultured in vitro. Embryonic or somatic cell nuclei do not undergo premature chromosome condensation when fused
