Summary
Plasmodesmata are plant cell channels that dynamically regulate molecule transport. The Drop-ANd-See (DANS) assay offers a non-invasive, real-time method to measure plasmodesmal permeability, aiding stress response studies.
Area of Science:
- Plant biology
- Cell biology
- Molecular biology
Background:
- Plasmodesmata are crucial for intercellular transport in plants.
- These channels exhibit dynamic regulation in response to various stimuli.
- Existing methods for monitoring plasmodesmata have limitations.
Purpose of the Study:
- To introduce fluorescence-based methods for studying plasmodesmata.
- To provide a detailed protocol for the Drop-ANd-See (DANS) assay.
- To enable non-invasive, real-time measurement of plasmodesmal permeability.
Main Methods:
- Review of fluorescence-based techniques for plasmodesmata research.
- Detailed step-by-step protocol for the Drop-ANd-See (DANS) assay.
- Discussion of experimental conditions for reliable DANS results.
Main Results:
- The DANS assay allows for non-invasive, in situ, real-time measurement of plasmodesmal permeability.
- The protocol aims to yield reliable and reproducible results.
- Troubleshooting guidance is provided for the DANS assay.
Conclusions:
- The DANS assay is a valuable tool for studying dynamic changes in plasmodesmal function.
- This method facilitates research into plant responses to physiological, developmental, and environmental factors.
- Understanding plasmodesmal permeability is key to plant cell communication and adaptation.

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.

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...

01:19Contact-dependent Signaling
46.5K
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.

01:46The Apoplast and Symplast
53.1K
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...

02:12Short-distance Transport of Resources
17.2K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

01:02Role of Microtubules in Cell Wall Deposition
2.8K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...
