Callose, a β-1,3-glucan polymer, appears to serve as both a structural and a regulatory element of plasmodesmata. It is synthesized by a callose synthase and degraded by a β-1,3-glucanase. The levels of callose deposits around plasmodesmata are not persistent but vary in response to internal and external signals or stresses, hence increasing or decreasing plasmodesmal permeability.
