Callose Synthase GSL7 Is Necessary for Normal Phloem Transport and Inflorescence Growth in Arabidopsis [PDF]
Plant Physiology, 2010 Abstract One isoform of callose synthase, Glucan Synthase-Like7 (GSL7), is tightly coexpressed with two isoforms of sucrose synthase (SUS5 and SUS6) known to be confined to phloem sieve elements in Arabidopsis (Arabidopsis thaliana). Investigation of the phenotype of gsl7 mutants of Arabidopsis revealed that the sieve plate pores of ...

RNAi-Mediated Attenuation of CsCalS7-Related Transcripts Mitigates Callose Accumulation and Huanglongbing Symptoms. [PDF]
Mol Plant PatholPartial CsCalS7 suppression reduces phloem callose, starch accumulation and huanglongbing symptoms, supporting a threshold‐based host tolerance. ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide and is characterised by excessive callose deposition at sieve plates, which has been associated with impaired carbohydrate ...

Biotechnology and Biotechnological Equipment, 2021 Callose plays an important role in plant development and response to multiple biotic and abiotic stresses. Callose synthase (CalS; EC 2.4.1.34), the main enzyme in callose synthesis, has been studied in a number of crops but not in cucumber (Cucumis ...

Callose Deposition: A Multifaceted Plant Defense Response [PDF]
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.

Solanum tuberosum glucan synthase-like 05 is involved in root-knot nematode Meloidogyne hapla parasitism [PDF]
Scientific ReportsThe Glucan Synthase-like 5 (GSL05) gene in potato is homologous to the Arabidopsis GSL05 that has a role in defense-related callose deposition. The role of GSL05-mediated callose deposition in potato roots during root-knot nematode Meloidogyne hapla ...

A Cell Plate-Specific Callose Synthase and Its Interaction with Phragmoplastin [PDF]
The Plant Cell, 2001 Abstract Callose is synthesized on the forming cell plate and several other locations in the plant. We cloned an Arabidopsis cDNA encoding a callose synthase (CalS1) catalytic subunit. The CalS1 gene comprises 42 exons with 41 introns and is transcribed into a 6.0-kb mRNA. The deduced peptide, with an approximate molecular mass of 226 kD,

Identification of Genes Involved in Resistance to Flavescence Dorée Disease of Grapevine: A Model Study Using Arabidopsis thaliana. [PDF]
Mol Plant PatholArabidopsis thaliana genes conferring resistance to flavescence dorée (FD) phytoplasma were identified, revealing vector‐independent defence mechanisms and providing potential targets for breeding FD‐resistant grapevine. ABSTRACT Flavescence dorée (FD), caused by FD phytoplasma (FDp) and transmitted by the leafhopper Scaphoideus titanus, is a ...

Role of callose accumulation in the suppression of calcium-deficiency-induced necrosis in Arabidopsis thaliana cotyledons [PDF]
Plant Signaling & BehaviorCalcium (Ca) deficiency symptoms, such as blossom end rot in tomato and tip burn in lettuce, are among the most serious physiological disorders in agriculture. A common feature of this disorder is the expansion of necrosis. However, mechanisms underlying

Evolutionary history of callose synthases in terrestrial plants with emphasis on proteins involved in male gametophyte development. [PDF]
PLoS ONE, 2017 Callose is a plant-specific polysaccharide (β-1,3-glucan) playing an important role in angiosperms in many developmental processes and responses to biotic and abiotic stresses.
