Recombinase polymerase amplification applied to plant virus detection and potential implications

Area of Science:

• Plant Pathology
• Molecular Diagnostics
• Virology

Background:

• Isothermal molecular techniques are advancing plant pathogen detection.
• Recombinase Polymerase Amplification (RPA) is emerging as a key method for plant virus identification.

Purpose of the Study:

• To review studies utilizing RPA for plant virus detection.
• To highlight RPA's advantages for field-based diagnostics.

Main Methods:

• Review of scientific literature on RPA applications in plant virology.
• Analysis of RPA performance for DNA and RNA plant viruses.

Main Results:

• RPA enables rapid, sensitive, and cost-effective plant virus detection.
• The technique requires minimal sample preparation and operates at a constant low temperature (37-42°C).
• RPA has been successfully applied to various DNA viruses (e.g., Banana bunchy top virus) and RNA viruses (e.g., Plum pox virus).

Conclusions:

• RPA is a promising tool for rapid plant virus diagnostics in plant clinics and quarantine services.
• Its field-deployable nature makes it valuable for agricultural monitoring.
• RPA offers a versatile solution for detecting a range of plant viruses.
