CalS7 encodes a callose synthase responsible for callose deposition in the phloem [PDF]
The Plant Journal, 2010 Summary It has been known for more than a century that sieve plates in the phloem in plants contain callose, a β‐1,3‐glucan. However, the genes responsible for callose deposition in this subcellular location have not been identified. In this paper we examine callose deposition patterns in T‐DNA insertion mutants (

Activation of Pollen Tube Callose Synthase by Detergents (Evidence for Different Mechanisms of Action) [PDF]
Plant Physiology, 1997 Abstract In pollen tubes of Nicotiana alata, a membrane-bound, Ca2+-independent callose synthase (CalS) is responsible for the biosynthesis of the (1,3)-β-glucan backbone of callose, the main cell wall component. Digitonin increases CalS activity 3- to 4-fold over a wide range of concentrations, increasing the maximum initial velocity ...

Identification of Callose Synthases in Stinging Nettle and Analysis of Their Expression in Different Tissues [PDF]
International Journal of Molecular Sciences, 2020 Callose is an important biopolymer of β-1,3-linked glucose units involved in different phases of plant development, reproduction and response to external stimuli. It is synthesized by glycosyltransferases (GTs) known as callose synthases (CalS) belonging to family 48 in the Carbohydrate-Active enZymes (CAZymes) database.

Novel localization of callose in the spores of Physcomitrella patens and phylogenomics of the callose synthase gene family [PDF]
Annals of Botany, 2009 Callose involvement in spore development is a plesiomorphic feature of land plants. Correlated light, fluorescence and immuno-electron microscopy was conducted on the developing spores of Physcomitrella patens to probe for callose. Using a bioinformatic approach, the callose synthase (PpCalS) genes were annotated and PpCalS and AtCalS gene families ...
