Peptide-based virus transmission control for orthotospoviruses

Overview

The peptide-based virus transmission control is an innovative approach designed to inhibit the spread of orthotospoviruses by thrips, a significant vector responsible for plant virus diseases. This solution uses specially formulated peptides that mimic virus glycoproteins to block virus attachment to insect cell receptors, reducing transmission by over two-thirds. By providing an environmentally friendly alternative to traditional pesticides, this technology aims to mitigate economic losses due to plant virus infections.

Technical specifications

Key features:

• Utilizes peptides that mimic virus glycoproteins to block virus-thrips interactions.
• Targets specific and broad-spectrum orthotospovirus clades, including tomato spotted wilt, impatiens necrotic spot, and iris yellow spot viruses.
• Employs microencapsulation techniques to enhance peptide stability and application efficiency.
• Optimized delivery methods using soybean vein necrosis virus as a model to determine effective spray rates and application techniques.

Technology readiness level

Currently at TRL 4, this technology has been validated in a laboratory setting with promising results. Future validation studies will focus on optimizing the formulation and application methods, assessing peptide efficacy against various orthotospovirus clades, and ensuring environmental persistence and regulatory compliance.
