Abstract

We report the cloning and characterization of two lectin genes from Medicago truncatula, designated Mtlec1 and Mtlec2. The two genes show a high degree of homology and apparently belong to a small multigene family. Mtlec1 appears to encode a functional lectin with 277 amino acids, whereas Mtlec2 is probably non-functional, since a frameshift mutation (insertion of two nucleotides) leads to premature translation termination after only 98 amino acids. The deduced amino acid sequence of the polypeptide MtLEC1 suggests that this lectin is a metalloprotein with Glc/Man specificity.
