Callose - Wikipedia
WEBCallose is a plant polysaccharide. Its production is due to the glucan synthase-like gene (GLS) in various places within a plant. It is produced to act as a temporary cell wall in response to stimuli such as stress or damage. [1]

Callose - an overview | ScienceDirect Topics
WEBCallose is a cell wall component that is produced by a few cell types, such as growing pollen tubes, cell plates of dividing cells, or cells affected by wounding or fungal infection. Callose consists of (1→3)β-d-glucan chains, which can form helical duplexes and triplexes. Genes encoding callose synthase (EC 2.4.1.34) have been isolated from ...
