Summary
Plant cells use plasmodesmata (PD) for molecule transport. Land plants evolved PD independently, with new research revealing their roles in development, physiology, and immunity.
Area of Science:
- Plant Biology
- Cell Biology
- Molecular Biology
Background:
- Plasmodesmata (PD) are crucial for intercellular communication in plants.
- Recent findings show land plants evolved PD independently from algae.
- Understanding PD structure and regulation is key to plant science.
Purpose of the Study:
- To review current knowledge on plasmodesmata (PD) in plants.
- To highlight the independent evolution of PD in land plants.
- To explore the roles of PD in plant development, physiology, and immunity.
Main Methods:
- Proteomic and genetic screens were used to identify PD components.
- Biochemical studies investigated the movement of immunological signals through PD.
- Literature review of recent advances in PD research.
Main Results:
- Land plants evolved plasmodesmata (PD) independently from their algal ancestors.
- Proteomic and genetic data reveal new insights into PD biogenesis pathways.
- Immunological signals move through PD to induce systemic defenses, with restricted transport observed during disease quarantine.
Conclusions:
- Plasmodesmata (PD) play multifaceted roles in plant development, physiology, and immunity.
- The independent evolution of PD in land plants highlights unique adaptations.
- Further research into PD regulation and function is essential for plant science.

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
48.2K
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.

Animal and plant cells not only differ in their structure, function, and mode of nutrition but also in how they reproduce, specialize, and organize into complex structures.
Cell Division
Though both plant and animal cells divide by mitosis (for non-gametic cells) and meiosis (for gametic cells), they differ in the specifics of this process. Unlike animal cells, plant cells lack centrosomes — an organelle responsible for organizing the spindle fibers and segregating the chromosomes during...

01:59The Phragmoplast
6.5K
Cell division is essential for organismal growth and development. In animal cells, the central spindle and its associated proteins form the midbody, a structure that has an essential role in cytokinesis. In plants, the central spindle, along with the microtubules, actin, and other cell components, matures into the phragmoplast, which is necessary for cytokinesis. Unlike the stationary midbody, the phragmoplast expands centrifugally, eventually leading to the formation of the new cell wall.

01:27Diversity of Protists IV
1.7K
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...
