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).

Characterization and Expression Analyses of Callose Synthase Enzyme (Cals) Family Genes in Maize (Zea mays L.)

Biochemical Genetics, 2021
The callose synthase enzyme genes (Cals) generally plays an important role in resisting to environmental stresses as well as in regulating the microspore development of higher plant. However till now, few researches about ZmCals genes have been reported in maize.

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

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 ...

An Arabidopsis callose synthase

Plant Molecular Biology, 2002
Beta-1,3-glucan polymers are major structural components of fungal cell walls, while cellulosic beta-1,4-glucan is the predominant polysaccharide in plant cell walls. Plant beta-1,3-glucan, called callose, is produced in pollen and in response to pathogen attack and wounding, but it has been unclear whether callose synthases can also produce cellulose ...

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.

Arabidopsis callose synthases CalS1/8 regulate plasmodesmal permeability during stress

Nature Plants, 2016
Plants need to cope with biotic and abiotic stress through well-coordinated cell-to-cell communication to survive as sedentary organisms. Environmental challenges such as wounding, low temperature, oxidative states and pathogen infection are known to affect the symplasmic molecular exchange between plant cells determined by plasmodesmal permeability ...

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 ...

N-Hydroxypipecolic acid and salicylic acid play key roles in autoimmunity induced by loss of the callose synthase PMR4.

Plant Physiology
In Arabidopsis thaliana, the POWDERY MILDEW RESISTANT4 (PMR4)/GLUCAN SYNTHASE LIKE5 (GSL5) callose synthase is required for pathogen-induced callose deposition in cell wall defense.
