Activation of Pollen Tube Callose Synthase by Detergents (Evidence for Different Mechanisms of Action) [PDF]
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]
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 (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
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.

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

The effects of infestation by the bird cherry-oat aphid (BCA), (Rhopalosiphum padi L) and the Russian wheat aphid (RWA) (Diuraphis noxia Mordvilko) on callose deposition and gene expression related to callose accumulation were investigated in barley ...

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