Summary
Researchers developed a new tool to control cell-to-cell communication in plants by temporarily blocking plasmodesmata (PD). This system aids in studying molecular movement and symplastic domain formation during plant development.
Area of Science:
- Plant Biology
- Cell Biology
- Molecular Biology
Background:
- Plasmodesmata (PD) are crucial for intercellular communication in plants.
- PD function is regulated by callose deposition, influencing molecular transport.
- Previous studies identified CALLOSE SYNTHASE 3 (CALS3) mutants affecting PD callose levels.
Purpose of the Study:
- To develop a tool for temporal and spatial control of symplastic connections in Arabidopsis.
- To investigate the role of symplastic domains in plant development and signaling.
- To enable the study of mobile signals and metabolite movement through PD.
Main Methods:
- Development of the "icals3m system" using an estradiol-inducible vector system.
- Combining semi-dominant CALLOSE SYNTHASE 3 (CALS3) mutations.
- Application of the system in conjunction with other methods to study signal transport and development.
Main Results:
- The "icals3m system" allows for inducible and spatially controlled obstruction of symplastic connections.
- The system has been successfully used to study the movement of mobile signals like SHR protein, microRNA165/6, and cytokinins in Arabidopsis roots.
- The tool facilitated understanding of symplastic domain formation during lateral root development.
Conclusions:
- The developed "icals3m system" is a valuable tool for plant research.
- This system can be used to investigate tissue-specific symplastic regulatory networks.
- It offers new possibilities for analyzing the symplastic movement of metabolites and signaling molecules.

In a multicellular organism, cells must communicate to work together in a coordinated manner. One way that cells communicate is through direct contact with other cells. The points of contact that connect adjacent cells are called intercellular junctions.
Intercellular junctions are a feature of fungal, plant, and animal cells. However, different types of junctions are found in different kinds of cells. Intercellular junctions found in animal cells include tight junctions, gap junctions, and...

The organs in a multicellular organism’s body are made up of tissues formed by cells. To work together cohesively, cells must communicate. One way that cells communicate is through direct contact with other cells. The points of contact that connect adjacent cells are called intercellular junctions.

01:19Contact-dependent Signaling
40.2K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

01:14Cell Adhesion in Plants
2.4K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

01:46The Apoplast and Symplast
51.4K
Plant growth depends on its ability to take up water and dissolved minerals from the soil. The root system of every plant is equipped with the necessary tissues to facilitate the entry of water and solutes. The plant tissues involved in the transport of water and minerals have two major compartments - the apoplast and the symplast. The apoplast includes everything outside the plasma membrane of living cells and consists of cell walls, extracellular spaces, xylem, phloem, and tracheids. The...

01:25Cell Signaling in Plants
4.5K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
