title: Occurrence and immunological relationships of lectins in gramineous species.
abstract: A survey of the occurrence of lectins in seeds from more than 100 grass species showed that all species belonging to the Triticeae tribe and the genera Brachypodium and Oryza contain lectins. All these lectins have the same sugar-binding specificity and are related to wheat-germ agglutinin, but to different degrees. Lectins from Triticeae species are immunologically indistinguishable from wheat lectin, whereas Brachypodium and rice lectins are only immunologically related to the wheat lectin. Attempts to detect lectin-deficient lines or varieties in wild and cultivated species of the three lectin-containing groups were unsuccessful. The possible use of lectins as a chemotaxonomic tool is discussed.
