Effect of repeated Ribavirin treatment on grapevine viruses
Acta Virologica
|December 9, 2016
Summary
Repeated Ribavirin treatment effectively increased healthy grapevine plants. Higher Ribavirin concentrations and longer exposure times significantly improved sanitation for specific grapevine viruses, enhancing plant health.
Area of Science:
- Plant pathology
- Virology
- Agricultural science
Background:
- Grapevine viruses pose a significant threat to viticulture worldwide.
- Effective sanitation methods are crucial for maintaining healthy vineyards and grape quality.
- Ribavirin is a known antiviral agent with potential applications in plant virus control.
Purpose of the Study:
- To evaluate the efficacy of Ribavirin treatment for grapevine virus chemotherapy.
- To determine the impact of Ribavirin concentration and treatment duration on virus elimination.
- To assess the effectiveness of Ribavirin across different grapevine cultivars and virus types.
Main Methods:
- Four grapevine cultivars were subjected to repeated Ribavirin treatments.
- Two different concentrations of Ribavirin were tested.
- Three distinct treatment durations were applied.
- The number of healthy grapevine plants and virus elimination rates were assessed.
Main Results:
- Repeated Ribavirin treatments consistently increased the number of healthy grapevine plants.
- Ribavirin concentration and treatment duration significantly impacted the sanitation of Grapevine rupestris stem pitting-associated virus.
- These factors did not show significant differences in the elimination of Grapevine Pinot gris virus and Grapevine fleck virus.
Conclusions:
- Ribavirin treatment, particularly when repeated, is a viable strategy for improving grapevine health by reducing viral load.
- Optimizing Ribavirin concentration and exposure duration is key for effective sanitation of certain grapevine viruses.
- Further research may be needed to refine Ribavirin application protocols for diverse grapevine viruses and cultivars.

1.2K
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

02:33Retroviruses
15.5K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

50.2K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
