Molecular Plant-Microbe Interactions : MPMI
|August 7, 2010
Summary
Plant viruses spread through plasmodesmata, channels enabling cell-to-cell communication. Viral movement proteins alter these channels, but molecular mechanisms require further study for understanding plant cell connectivity.
Area of Science:
- Plant Biology
- Virology
- Cell Biology
Background:
- Plasmodesmata are crucial for intercellular transport in plants.
- Plant viruses exploit plasmodesmata for systemic spread.
- Viral movement proteins are key to manipulating plasmodesmata.
Purpose of the Study:
- To review the structure and function of plasmodesmata.
- To explore how viruses modify plasmodesmata for macromolecular trafficking.
- To highlight the role of viral movement proteins in this process.
Main Methods:
- Literature review of plasmodesmata structure and function.
- Analysis of viral strategies for manipulating plasmodesmata.
- Discussion of viral movement protein mechanisms.
Main Results:
- Plasmodesmata facilitate local and systemic virus movement.
- Viruses induce functional changes in plasmodesmata for macromolecular transport.
- Viral movement proteins are essential for this viral-induced trafficking.
Conclusions:
- Understanding plasmodesmata-virus interactions is vital for plant health.
- Viral movement proteins are valuable tools for studying plasmodesmata.
- Further research into molecular mechanisms is needed to fully elucidate these interactions.

02:32Plasmodesmata
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.Intercellular junctions are a feature of fungal, plant, and animal cells alike. However, different types of junctions are found in different kinds of cells. Intercellular junctions found in animal...

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.

01:19Contact-dependent Signaling
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.

01:10Intracellular Movement of Viruses and Bacteria
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a virus that...
01:20Infection
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

00:56Viral Structure
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.
