Plasmodesmata

3.3K
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...

Role of Microtubules in Cell Wall Deposition01:02

Role of Microtubules in Cell Wall Deposition

2.6K
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...

Area of Science:

  • Plant Biology
  • Developmental Biology
  • Bryophyte Research

Background:

  • Bryophytes, as early land plants, possess plasmodesmata in various tissues.
  • The role of plasmodesmata in bryophyte development is under-investigated.
  • Callose deposition around plasmodesmata may influence moss development and physiology.

Purpose of the Study:

  • To present a protocol for imaging and quantifying callose in the moss Physcomitrium (Physcomitrella) patens.
  • To establish a general framework for studying callose distribution in other bryophytes.

Main Methods:

  • Detailed protocol for callose imaging in the filamentous body of Physcomitrium (Physcomitrella) patens.
  • Quantitative analysis of callose levels.
  • Discussion of potential alternatives and experimental challenges.

Main Results:

  • A reproducible method for visualizing and quantifying callose in mosses is provided.
  • The protocol is applicable to the model moss Physcomitrium (Physcomitrella) patens.

Conclusions:

  • The developed protocol facilitates the study of callose's role in bryophyte development.
  • This research offers a foundation for exploring plasmodesmatal regulation by callose in diverse bryophyte species.
