Barley stripe mosaic virions assoicated with spindle microtubules
Science (New York, N.Y.)
|September 13, 1974
Abstract:
Virions of barley stripe mosaic virus were observed attached to microtubules of the spindle apparatus. This phenomenon was found in barley cells undergoing meiosis and mitosis. The microtubules may be involved in the assembly and cell-to-cell transfer of the virus.
Insights
Barley stripe mosaic virus particles attach to spindle apparatus microtubules in plant cells during cell division. These microtubules may aid in virus assembly and spread between cells.
Area of Science:
- Plant pathology
- Cell biology
- Virology
Background:
- Barley stripe mosaic virus (BSMV) is a significant pathogen affecting barley crops.
- Understanding virus-host interactions is crucial for developing disease management strategies.
Purpose of the Study:
- To investigate the interaction between BSMV virions and host cell structures.
- To explore the potential role of specific cellular components in BSMV replication and dissemination.
Main Methods:
- High-resolution microscopy techniques were employed to visualize BSMV virions within barley cells.
- Cellular structures, particularly the spindle apparatus, were examined during different stages of cell division.
Main Results:
- BSMV virions were consistently observed attached to microtubules of the spindle apparatus.
- This attachment was noted in both meiotic and mitotic barley cells.
Conclusions:
- Microtubules of the spindle apparatus are a potential site for BSMV virion association.
- These microtubules may play a role in the assembly and/or cell-to-cell movement of BSMV.
