Phloem-specific hairpin RNA expression confers broad-spectrum antiviral resistance in elite rice cultivars

Key Points

• The aim is to enhance antiviral resistance in rice by targeting hairpin RNA expression to vascular tissue.
• Expressed hairpin RNA specifically in phloem of elite rice cultivars.
• Evaluated resistance against multiple insect-borne viruses.
• Assessed growth and grain yield to ensure preservation of normal functions.
• Significantly blocked multiple insect-borne viruses.
• Maintained normal growth of rice plants.
• Sustained grain yield comparable to non-engineered plants.
