Callose in leptoid cell walls of the moss Polytrichum and the evolution of callose synthase across bryophytes

Frontiers in Plant Science
IntroductionLeptoids, the food-conducting cells of polytrichaceous mosses, share key structural features with sieve elements in tracheophytes, including an elongated shape with oblique end walls containing modified plasmodesmata or pores.

Replicase-Mediated Resistance to Cucumber Mosaic Virus Does Not Inhibit Localization and/or Trafficking of the Viral Movement Protein

Molecular Plant-Microbe Interactions, 1999
Replicase-mediated resistance to cucumber mosaic virus (CMV) affects CMV replication and restricts CMV movement. Confocal laser scanning microscopic analysis of resistant plants inoculated with either CMV or potato virus X, expressing the CMV movement ...

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.

Live-cell RNA imaging with the inactivated endonuclease Csy4 enables new insights into plant virus transport through plasmodesmata.

PLoS Pathogens
Plant-infecting viruses spread through their hosts by transporting their infectious genomes through intercellular nano-channels called plasmodesmata. This process is mediated by virus-encoded movement proteins.

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

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

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.

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 ...
