Antigenically similar chitin-binding lectins are present in the embryos of wheat, barley, and rye, members of the Triticeae tribe of the grass family (Gramineae). However, the lectins display different localization patterns in these embryos. Lectin is absent from the coleoptile of barley but is present in the outer surface cells of this organ in wheat and in both inner and outer surface cells of rye coleoptiles. All three cereals contain lectin at the periphery of embryonic roots. Similar lectins were not detected in oats and pearl millet, members of other tribes of the Gramineae. Rice, a species only distantty related to wheat, contains a lectin that is antigenically similar to the other cereal lectins and located at the periphery of embryonic roots and throughut the coleoptile.
