A coordinated switch in sucrose and callose metabolism enables enhanced symplastic unloading in potato tubers

Quantitative Plant Biology
One of the early changes upon tuber induction is the switch from apoplastic to symplastic unloading. Whether and how this change in unloading mode contributes to sink strength has remained unclear.

Genome‐wide analysis of the callose enzyme families of fertile and sterile flower buds of the Chinese cabbage (Brassica rapa L. ssp. pekinensis)

FEBS Open Bio, 2019
Callose is a β‐1,3‐glucan commonly found in higher plants that plays an important role in regulating plant pollen development. It is synthesized by glucan synthase‐like (GSL) and is degraded by the enzyme endo‐1,3‐β‐glucosidase.

EDS1 Contributes to Nonhost Resistance of Arabidopsis thaliana Against Erwinia amylovora

Molecular Plant-Microbe Interactions, 2012
Erwinia amylovora causes fire blight in rosaceous plants. In nonhost Arabidopsis thaliana, E. amylovora triggers necrotic symptoms associated with transient bacterial multiplication, suggesting either that A.

Molecular and biochemical studies of cellulose and callose synthase

, 2002
Cotton fibers consist of almost pure cellulose in the secondary wall stage. To isolate a cellulose synthase gene from cotton, the catalytic region of cellulose synthase in Aceobacter xylinum was used to search the EST database.

The Arabidopsis thaliana Knockout Mutant for Phytochelatin Synthase1 (cad1-3) Is Defective in Callose Deposition, Bacterial Pathogen Defense and Auxin Content, But Shows an Increased Stem Lignification

Frontiers in Plant Science, 2018
The enzyme phytochelatin synthase (PCS) has long been studied with regard to its role in metal(loid) detoxification in several organisms, i.e., plants, yeasts, and nematodes. It is in fact widely recognized that PCS detoxifies a number of heavy metals by

The knowns and unknowns of callose biosynthesis in terrestrial plants

Callose, a linear (1,3)-β-glucan, is an indispensable carbohydrate polymer required for plant growth and development. Advances in biochemical, genetic, and genomic tools, along with specific antibodies, have significantly enhanced our understanding of ...

Molecular diversity of citrus genotypes using callose synthase 7 gene markers linked to Huanglongbing resistance

Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus, is a notable disease affecting citrus plantations globally. Several studies showed that the callose synthase 7 gene is crucial for the citrus defense system against this pathogen.

Callose and Salicylic Acid Are Key Determinants of Strigolactone-Mediated Disease Resistance in Arabidopsis

Plants
Research has demonstrated that strigolactones (SLs) mediate plant disease resistance; however, the basal mechanism is unclear. Here, we provide key genetic evidence supporting how SLs mediate plant disease resistance.

Morphological and Molecular Analyses of Host and Nonhost Interactions Involving Barley and Wheat and the Covered Smut Pathogen Ustilago hordei

Molecular Plant-Microbe Interactions, 2010
Ustilago hordei interactions on coleoptiles of barley host cultivars Odessa (compatible), Hannchen (incompatible, carrying the Ruh1 resistance gene), and on nonhost Neepawa wheat were studied using light and fluorescent microscopy.

Mechanisms and regulation of callose deposition to the cell wall of Arabidopsis thaliana

, 2016
Callose (β-1,3-glucan) is a significant plant cell wall polysaccharide, which participates in many developmental and stress responses. Despite the importance of this polymer, the knowledge on the causes of callose synthesis, its regulation and the ...
