Abstract The binding patterns of four different lectins conjugated to horseradish peroxidase were investigated in the nervous system of juvenile Xenopus borealis. Only the lectin soybean agglutinin revealed a very selective binding pattern, which was restricted to the olfactory system. The olfactory and vomeronasal epithelia, the olfactory and accessory olfactory nerves and the olfactory and accessory olfactory bulbs were all labelled. The ventral portions of the olfactory nerve and bulb were however more intensely labelled than their dorsal portions. The rest of the brain and spinal cord did not bind this lectin except for a small discrete set of unmyelinated axons travelling in the medial forebrain bundle. Ultrastructural investigations revealed that soybean agglutinin was confined to the cell surface of olfactory neurons. The selective binding of this lectin to olfactory neurons suggests that specific cell surface glycoconjugates binding soybean agglutinin may have either a functional or developmental role in the olfactory system of Xenopus.
