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 ...

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.

Overexpression of a Prefoldin β subunit gene reduces biomass recalcitrance in the bioenergy crop Populus. [PDF]
, 2020 Prefoldin (PFD) is a group II chaperonin that is ubiquitously present in the eukaryotic kingdom. Six subunits (PFD1-6) form a jellyfish-like heterohexameric PFD complex and function in protein folding and cytoskeleton organization.

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.

Gene regulatory networks elucidating huanglongbing disease mechanisms. [PDF]
, 2013 Next-generation sequencing was exploited to gain deeper insight into the response to infection by Candidatus liberibacter asiaticus (CaLas), especially the immune disregulation and metabolic dysfunction caused by source-sink disruption.

Plant Physiology, 2022 Abstract Callose is a plant cell wall polysaccharide whose deposition is spatiotemporally regulated in various developmental processes and environmental stress responses. The appearance of callose in premeiotic anthers is a prominent histological hallmark for the onset of meiosis in flowering plants; however, the biological role of ...

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 ...

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.
