Plasmodesmata and their role in assimilate translocation

Journal of Plant Physiology, 2022
During multicellularization, plants evolved unique cell-cell connections, the plasmodesmata (PD). PD of angiosperms are complex cellular domains, embedded in the cell wall and consisting of multiple membranes and a large number of proteins. From the beginning, it had been assumed that PD provide passage for a wide range of molecules, from ions to ...

Subcellular Localization of Iron in Rhizophora mangle Leaves Revealed by Integrated Perls Reaction, TEM, STEM‐HAADF, and EDS Analyses

Microscopy Research and Technique, EarlyView.
Perls–TEM–STEM‐HAADF–EDS enables high‐resolution localization and elemental characterization of Fe‐containing deposits in Rhizophora mangle leaf cells. ABSTRACT Mangrove ecosystems are frequently exposed to high concentrations of iron (Fe) in sediments, resulting in Fe accumulation in plant tissues. Although Fe is an essential micronutrient involved in

Plasmodesmata spread their influence [PDF]

F1000Prime Reports, 2015
Plasmodesmata (PDs) are microscopic channels that connect virtually every plant cell to its neighbors. They also provide a route for molecules to access the phloem for systemic movement throughout the plant. In this report, I review recent findings that broaden the potential impact of these channels, by revealing their contribution to auxin movement ...

Reactive oxygen species, antioxidants and the regulation of plant development

The FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

PtoHY5 integrates photoperiodic signals with the ABA pathway to coordinate growth cessation and dormancy in Populus

Journal of Integrative Plant Biology, EarlyView.
In Populus, short days deactivate the growth‐promoting protein PtoHY5, turning off a growth accelerator and activating an abscisic acid‐driven brake. This directly couples growth cessation with dormancy, underscoring the role of abscisic acid in synchronizing these transitions for winter survival.

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

Interaction between Movement Proteins of Hibiscus green spot virus

Viruses, 2022
Movement proteins (MPs) of plant viruses enable the translocation of viral genomes from infected to healthy cells through plasmodesmata (PD). The MPs functions involve the increase of the PD permeability and routing of viral genome both to the PD ...

Sugars as Central Integrators of Plant Immunity and Stress Responses

Plant, Cell &Environment, EarlyView.
ABSTRACT Sugars are fundamental metabolites that sustain plant growth and development, but accumulating evidence demonstrates that they also function as regulatory hubs in plant defence. In this review, we synthesise current knowledge on how carbohydrate dynamics coordinate metabolism, signalling, and structural responses to shape plant resistance ...

Auxin fluxes through plasmodesmata [PDF]

New Phytologist, 2021
SummaryCharacterising the processes that control auxin dynamics is essential to understanding how auxin regulates plant development. Over recent years, several studies have investigated auxin diffusion through plasmodesmata, characterising this cell‐to‐cell diffusion and demonstrating that it affects auxin distributions. Furthermore, studies have shown

Tracking Sodium Inside the Plant: Hydraulic Adjustments to Deal With Salinity

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
ABSTRACT Sorghum is a crop that has become more relevant in recent years due to its uses and properties (biofuel, gluten‐free flour) as well as its versatility to grow in unfavourable environmental conditions. Salinity is one of the main abiotic stresses affecting crop production and yield worldwide.
