Plasmodesmata [PDF]

The Plant Cell, 2002
A new paradigm is emerging in plant biology in which proteins and ribonucleoprotein (RNP) complexes play non-cell-autonomous roles in contributing to the control over developmental and physiological processes. Plasmodesmata (PD), the intercellular organelle(s) of the plant kingdom, create the pathway for the cell-to-cell trafficking of these ...

Identification of a Functional Plasmodesmal Localization Signal in a Plant Viral Cell-To-Cell-Movement Protein

mBio, 2016
Our fundamental knowledge of the protein-sorting pathways required for plant cell-to-cell trafficking and communication via the intercellular connections termed plasmodesmata has been severely limited by the paucity of plasmodesmal targeting sequences ...

Putting the Squeeze on Plasmodesmata: A Role for Reticulons in Primary Plasmodesmata Formation [PDF]

Plant Physiology, 2015
Primary plasmodesmata (PD) arise at cytokinesis when the new cell plate forms. During this process, fine strands of endoplasmic reticulum (ER) are laid down between enlarging Golgi-derived vesicles to form nascent PD, each pore containing a desmotubule, a membranous rod derived from the cortical ER.

Distributing Plant Developmental Regulatory Proteins via Plasmodesmata

Plants
During plant development, mobile proteins, including transcription factors, abundantly serve as messengers between cells to activate transcriptional signaling cascades in distal tissues.

Phloem unloading in Arabidopsis roots is convective and regulated by the phloem-pole pericycle

eLife, 2017
In plants, a complex mixture of solutes and macromolecules is transported by the phloem. Here, we examined how solutes and macromolecules are separated when they exit the phloem during the unloading process.

Enviromics crosstalk between internal and external plant environments for enhanced adaptation and de novo domestication

iMeta, EarlyView.
Climate change demands accelerated plant adaptation and de novo domestication. Yet current enviromics focuses disproportionately on external environments, neglecting internal dynamics—gene expression, metabolic flux, and signal transduction—within predictive envirotyping frameworks.

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 ...

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

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.
