Plasmodesmata: gatekeepers for cell-to-cell transport of developmental signals in plants.

Annual review of cell and developmental biology·2000

Plant viruses spread using plasmodesmata, the cell-to-cell connections that allow molecule transport. This study explores how viruses hijack this network for efficient genome dissemination within plants.

Area of Science:

  • Plant virology
  • Cell biology
  • Molecular plant pathology

Background:

  • Plant viruses utilize plasmodesmata for intercellular movement.
  • Plasmodesmata form a crucial network for molecule transport in plants.

Purpose of the Study:

  • To investigate the mechanisms by which viruses exploit plasmodesmata for genome spread.
  • To understand the role of plasmodesmata in plant virus infection.

Main Methods:

  • Analysis of virus-genome interactions with plasmodesmata components.
  • Microscopy techniques to visualize virus movement through the plant cell network.

Main Results:

  • Viruses actively manipulate plasmodesmata to facilitate their genome's passage.

  • Specific viral factors are identified that mediate plasmodesmata modification.

    • Conclusions:

    • Viral exploitation of plasmodesmata is a key strategy for systemic infection.
    • Targeting virus-plasmodesmata interactions could offer novel strategies for disease control.
