Chamberland, J. Lafontaine] Summary: Sugars have been demonstrated in animal cell nuclei, but only a few studies have mentioned their presence in plant cell nuclei. In this studyl-fucose residues were localized at the ultrastructural level, usingUlex europeaus agglutinin I lectin, during the early stages of germination ofPisum sativum and in mature root tip cells. This sugar was present after 1 h of germination, and its concentration was found to vary during 3 to 6 h imbition; after 72 h of imbition its concentration had more than doubled. Furthermore, labelling was particularly abundant in the nucleolus, nucleolus-associated bodies and dense nuclear bodies. The possibility that some of thel-fucose residues are associated with proteins is discussed. Chapman & Hall, 1992 Chamberland H.
