Callose

  [kal-ohs]
Callose is a plant polysaccharide. It is comprised of glucose residues linked together through b-1,3-linkages, and is termed a B-glucan. It is thought to be manufactured at the cell wall by callose synthases and is degraded by b-1,3-glucanases. It is laid down at plasmodesmata, at the dividing cell plate and during pollen development. It is produced in response to wounding, infection by pathogens, aluminium and abscisic acid.
