The DENN Protein SMD1 Forms a Signalling Hub With Rab GTPase YPT1 to Regulate Diverse Biological Processes in Phytopathogenic Fungi and Serves as a HIGS Target for Crop Protection

open access: yesMolecular Plant Pathology, Volume 27, Issue 6, June 2026.
The DENN domain‐containing protein SsSMD1 is highly conserved across phytopathogenic fungi. Functioning as a putative GEF for RAS GTPase SsYPT1, SsSMD1 orchestrates its activation to regulate cell wall integrity, sclerotia development, and virulence in Sclerotinia sclerotiorum.

The Cell Wall-Derived Xyloglucan Is a New DAMP Triggering Plant Immunity in Vitis vinifera and Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2018
Damage-associated molecular patterns (DAMPs) are endogenous molecules that can activate the plant innate immunity. DAMPs can derive from the plant cell wall, which is composed of a complex mixture of cellulose, hemicellulose, and pectin polysaccharides ...

Callose homeostasis at plasmodesmata: molecular control and developmental regulation.

open access: yesFrontiers in Plant Science, 2014
Plasmodesmata are membrane-lined channels that are located in the plant cell wall and that physically interconnect the cytoplasm of adjacent cells.

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

open access: yesQuantitative 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)

open access: yesFEBS 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

open access: yesMolecular 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.

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

open access: yesFrontiers 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

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

open access: yesPlants
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

open access: yesMolecular 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.

Characteristics and Transcriptome Analysis of Anther Abortion in Male Sterile Celery (Apium graveolens L.)

open access: yesHorticulturae
To elucidate the molecular mechanisms underlying anther abortion in celery male sterile lines, this study investigates the morphological differences of floral organs and differential gene expression patterns between two lines at the flowering stage ...
