Cucumber green mottle mosaic virus: A persistent seed‐borne threat to cucurbits

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Cucumber green mottle mosaic virus (CGMMV) is a highly stable, seed‐borne tobamovirus that threatens global cucurbit production. Its efficient mechanical and seed transmission, long‐term environmental persistence, and the spread of Clade II CGMMV isolates drive its rapid dissemination and cause severe yield losses.

TIP, A Novel Host Factor Linking Callose Degradation with the Cell-to-Cell Movement of Potato virus X

Molecular Plant-Microbe Interactions, 2003
The cell-to-cell movement of Potato virus X (PVX) requires four virus-encoded proteins, the triple gene block (TGB) proteins (TGB25K, TGB12K, and TGB8K) and the coat protein. TGB12K increases the plasmodesmal size exclusion limit (SEL) and may, therefore,

Gatekeepers and Gatecrashers of the Symplasm: Cross-Kingdom Effector Manipulation of Plasmodesmata in Plants

Plants
Plasmodesmata (PD) are dynamic nanochannels interconnecting plant cells and coordinating development, nutrient distribution, and systemic defense. Their permeability is tightly regulated by callose turnover, PD-localized proteins, lipid microdomains, and

Plasmodesmata play a key role in leaf vein patterning

PLoS Biology, 2022
Leaf veins provide a vital transport route in plants. The formation of leaf vein patterns has fascinated many scientists. In PLOS Biology, Linh and Scarpella reveal that transport through plasmodesmata plays a key role in vein patterning.

The Plasmodesmal Localization Signal of TMV MP Is Recognized by Plant Synaptotagmin SYTA

mBio, 2018
Plant viruses cross the barrier of the plant cell wall by moving through intercellular channels, termed plasmodesmata, to invade their hosts. They accomplish this by encoding movement proteins (MPs), which act to alter plasmodesmal gating. How MPs target

Substructure of Plasmodesmata [PDF]

, 1999
Plasmodesmata now appear to be highly dynamic structures which are able to select and transport even large molecules from cell to cell (for review, see Zambryski1995). It has become crucial to understand the substructural architecture of plasmodesmata and the molecular interactions that control the intercellular passage of molecules and viruses.

Proteomic analysis provides integrated insight into mechanisms of Turnip mosaic virus long distance movement in Brassica rapa

Biologia Plantarum, 2019
In non-heading Chinese cabbage, the yield relies mostly on the health of leaves, which can be heavily impacted by turnip mosaic virus (TuMV). The virions or viral ribonucleoprotein complexes are transported through the phloem and xylem. Plasmodesmata are

Fruit Morphology and Seed Anatomy of Ormosia macrocalyx Ducke

Seeds
Ormosia macrocalyx grows in tropical forests and is endangered in Mexico. The species has ecological and economic importance. To evaluate the relationship between fruit length and seed number, Pearson correlation and principal component analysis were ...

Plasmodesmata-Mediated Cell-to-Cell Communication in the Shoot Apical Meristem: How Stem Cells Talk

Plants, 2017
Positional information is crucial for the determination of plant cell fates, and it is established based on coordinated cell-to-cell communication, which in turn is essential for plant growth and development.

The ultrastructure of plasmodesmata

Protoplasma, 1971
It is suggested that the central strand which traverses plasmodesmata is in open continuity with the endoplasmic reticulum of adjacent cells, and that this strand (desmotubule) represents a modulation of a normal ER membrane so that it comprises solely spherical protein subunits.
