Analysis of a novel mutant allele of GSL8 reveals its key roles in cytokinesis and symplastic trafficking in Arabidopsis

BMC Plant Biology, 2018
Background Plant cell walls are mainly composed of polysaccharides such as cellulose and callose. Callose exists at a very low level in the cell wall; however, it plays critical roles at different stages of plant development as well as in defence against

The Mobile Small RNAs: Important Messengers for Long-Distance Communication in Plants

Frontiers in Plant Science, 2022
Various species of small RNAs (sRNAs), notably microRNAs and small interfering RNAs (siRNAs), have been characterized as the major effectors of RNA interference in plants.

Plasmodesmata of brown algae [PDF]

Journal of Plant Research, 2014
Abstract Plasmodesmata (PD) are intercellular connections in plants which play roles in various developmental processes. They are also found in brown algae, a group of eukaryotes possessing complex multicellularity, as well as green plants. Recently, we conducted an ultrastructural study of PD in several species of brown algae.

Uncharted routes: exploring the relevance of auxin movement via plasmodesmata

Biology Open, 2020
Auxin is an endogenous small molecule with an incredibly large impact on growth and development in plants. Movement of auxin between cells, due to its negative charge at most physiological pHs, strongly relies on families of active transporters.

Enviromics crosstalk between internal and external plant environments for enhanced adaptation and <i>de novo</i> domestication. [PDF]

Imeta
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.

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.

From apex to base: Uncovering spatial metabolic adaptation in Antarctic mosses

Bulletin of the Korean Chemical Society, EarlyView.
Antarctic mosses survive extreme cold, desiccation, UV exposure, and oxidative stress. We analyzed three species by separating apical, middle, and basal zones. Each zone showed distinct metabolite patterns and biological roles, revealing spatial metabolic specialization. The results suggest that whole‐plant survival depends on coordinated contributions
