Natural tech for ‘dimming’ genes brings transformative potential to agriculture

By | Agriculture, News, Plant Science

Advancements in RNA interference (RNAi) technology are revolutionizing agriculture, offering precise gene-silencing capabilities akin to dimming a light switch rather than turning it off completely like CRISPR. RNAi, a natural defense mechanism in organisms, enables targeted gene modification, enhancing crop traits and reducing reliance on pesticides. Exciting applications include virus-resistant papaya and low-toxicity cottonseed, marking a sustainable shift in global food production. As regulatory acceptance grows, RNAi promises safer, more efficient agricultural practices, heralding a future of enhanced food security and environmental stewardship.
