Lectins, lectin genes, and their role in plant defense

Author(s): Chrispeels MJ, Raikhel NV

Abstract

Lectins are carbohydrate-binding proteins that bind glycans of glycoproteins, glycolipids, or polysaccharides with high affinity (Goldstein and Hayes, 1978). Because of their binding specificity, they have the capability to serve as recognition molecules within a cell, between cells, or between organisms. It is assumed that lectins play fundamental biological roles in plants because they are found in many different species and in many different organs and tissues.
