A comprehensive view on organ-specific callose synthesis in wheat (Triticum aestivum L.): glucan synthase-like gene expression, callose synthase activity, callose quantification and deposition

Plant Physiology and Biochemistry, 2006
Callose ((1,3)-beta-glucan) is important during basic developmental processes of plants, but only little is known about the regulation of callose biosynthesis on molecular level. Growing evidence indicates that glucan synthase-like (GSL) genes in higher plants are involved in callose synthesis.

A novel callose synthase from pollen tubes of Nicotiana

Planta, 1993
Pollen-tube cell walls are unusual in that they are composed almost entirely of callose, a (1,3)-β-linked glucan with a few 6-linked branches. Regulation of callose synthesis in pollen tubes is under developmental control, and this contrasts with the deposition of callose in the walls of somatic plant cells which generally occurs only in response to ...

Plant callose synthase complexes

Plant Molecular Biology, 2001
Synthesis of callose (beta-1,3-glucan) in plants has been a topic of much debate over the past several decades. Callose synthase could not be purified to homogeneity and most partially purified cellulose synthase preparations yielded beta-1,3-glucan in vitro, leading to the interpretation that cellulose synthase might be able to synthesize callose ...

Callose synthase (CalS5) is required for exine formation during microgametogenesis and for pollen viability in Arabidopsis [PDF]

Plant Journal, 2005
SummaryCallose (β‐1,3‐glucan) is produced at different locations in response to biotic and abiotic cues. Arabidopsis contains 12 genes encoding callose synthase (CalS). We demonstrate that one of these genes, CalS5, encodes a callose synthase which is responsible for the synthesis of callose deposited at the primary cell wall of meiocytes, tetrads and ...

PbrCalS5, a callose synthase protein, is involved in pollen tube growth in Pyrus bretschneideri

Planta, 2022
Identification of CalS genes in seven Rosaceae species and functional characterization of PbrCalS5 in pear pollen tube growth by regulating callose deposition. Callose exists widely in angiosperms and has significant functions in a range of developmental processes. Callose is synthesized by callose synthase (CalS).

Expression of Arabidopsis callose synthase 5 results in callose accumulation and cell wall permeability alteration

Plant Science, 2012
Callose is the major polysaccharide present in the callose wall of developing microspores and the growing pollen tube wall. It is also an essential component of other specialized cell walls and its synthesis can be induced by pathogen infection, wounding and environmental cues.

Loss of a Callose Synthase Results in Salicylic Acid-Dependent Disease Resistance

Science, 2003
Plants attacked by pathogens rapidly deposit callose, a β-1,3-glucan, at wound sites. Traditionally, this deposition is thought to reinforce the cell wall and is regarded as a defense response. Surprisingly, here we found that powdery mildew resistant 4 ( pmr4

Epigenetic silencing of callose synthase by VIL1 promotes bud-growth transition in lily bulbs

Nature Plants, 2023
In plants, restoring intercellular communication is required for cell activity in buds during the growth transition from slow to fast growth after dormancy release. However, the epigenetic regulation of this phenomenon is far from understood. Here we demonstrate that lily VERNALIZATION INSENSITIVE 3-LIKE 1 (LoVIL1) confers growth transition by ...
