A plant polysaccharide comprising glucose residues linked together through u03B2-1,3-linkages, produced chiefly in response to wounding and infection.
furnished with protuberant or hardened spots
Origin: [See Callous.]
Callose is a plant polysaccharide. It is composed of glucose residues linked together through β-1,3-linkages, and is termed a β-glucan. It is thought to be manufactured at the cell wall by callose synthases and is degraded by β-1,3-glucanases. It is laid down at plasmodesmata, at the cell plate during cytokinesis and during pollen development. It is produced in response to wounding, infection by pathogens, aluminium and abscisic acid. Deposits often appear on the sieve plates at the end of the growing season. Callose also forms immediately around the developing meiocytes and tetrads of sexually reproducing angiosperms but is not found in related apomictic taxa.
