cal·lose

(kal'ōs),
A linear 1,3-β-d-glucan formed by certain enzymes from UDP-glucose, differing from cellulose (a β-1,4-glucan formed from GDP-glucose) and starch amylose (an α-1,4-glucan formed from ADP-glucose). Found in certain plant cell walls.

callose

a thick CARBOHYDRATE plant material deposited in the pores of sieve plates in response to damage, disease or simply over a period of time, resulting in a blockage of the SIEVE TUBE. Callose is also present in the walls of fungal hyphae.
