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 ...

The Arabidopsis Callose Synthase Gene GSL8 Is Required for Cytokinesis and Cell Patterning     [PDF]

Plant Physiology, 2009
Abstract Cytokinesis is the division of the cytoplasm and its separation into two daughter cells. Cell plate growth and cytokinesis appear to require callose, but direct functional evidence is still lacking. To determine the role of callose and its synthesis during cytokinesis, we identified and characterized mutants in many members of ...

Silicon amendment to rice plants contributes to reduced feeding in a phloem‐sucking insect through modulation of callose deposition

Ecology and Evolution, 2018
Silicon (Si) uptake by Poaceae plants has beneficial effects on herbivore defense. Increased plant physical barrier and altered herbivorous feeding behaviors are documented to reduce herbivorous arthropod feeding and contribute to enhanced plant defense.

Recovery from stolbur disease in grapevine involves changes in sugar transport and metabolism

Frontiers in Plant Science, 2013
Grapevine can be severely affected by phytoplasmas, which are phytopathogenic Mollicutes invading the sieve elements of the host plant. The biochemical and molecular relationships between phytoplasmas and their hosts remain largely unexplored.

Genomic Identification of Callose Synthase (CalS) Gene Family in Sorghum (Sorghum bicolor) and Comparative In Silico Expression Analysis under Aphid (Melanaphis sacchari) Infestation

Agronomy
Callose is widely present in higher plants and plays a significant role in plant growth, development, and response to various stresses. Although numerous studies have highlighted the importance of the callose synthase (CalS) genes, their role in the ...

Exocyst Subunit EXO70H4 Has a Specific Role in Callose Synthase Secretion and Silica Accumulation [PDF]

Plant Physiology, 2018
Biogenesis of the plant secondary cell wall involves many important aspects, such as phenolic compound deposition and often silica encrustation. Previously, we demonstrated the importance of the exocyst subunit EXO70H4 for biogenesis of the trichome secondary cell wall, namely for deposition of the autofluorescent and callose-rich cell wall layer. Here,

Callose Deposition: A Multifaceted Plant Defense Response

Molecular Plant-Microbe Interactions, 2011
Callose deposition in Arabidopsis has emerged as a popular model system to quantify activity of plant immunity. However, there has been a noticeable rise in contradicting reports about the regulation of pathogen-induced callose.

Localization of Arabidopsis Glucan Synthase-Like 5, 8, and 12 to plasmodesmata and the GSL8-dependent role of PDLP5 in regulating plasmodesmal permeability

Plant Signaling & Behavior, 2023
Cell-to-cell communication via membranous channels called plasmodesmata (PD) plays critical roles during plant development and in response to biotic and abiotic stresses.

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Callose Synthase Family Genes Involved in the Grapevine Defense Response to Downy Mildew Disease [PDF]

Phytopathology®, 2016
The deposition of callose is a common plant defense response to intruding pathogens and part of the plant’s innate immunity. In this study, eight grapevine callose synthase (CalS) genes were identified and characterized. To investigate biological function of CalS in grapevine against the infection of Plasmopara viticola, expression patterns of ...
