PSL — Phaseolus vulgaris

Summary

PHAVU_004G158300, designated PvPSL (also known as PvLEC1) on chromosome 4 of French bean (Phaseolus vulgaris), encodes a leguminous lectin family protein with a ConA-like domain. The product exhibits D-mannose, sugar, calcium ion, and manganese binding activities, as well as toxin activity. This gene is associated with defence responses to bacteria and fungi, killing of cells of other organisms, and nitric oxide storage. It is linked to macromolecule complex localisation. Related genes in other species, including seed lectin alpha and beta chains, DLEC1, DLEC2, and PHA-L, are associated with seed traits such as seed weight, seed coat colour, protein and amino acid content, oligosaccharide content, and seed maturation.
