World’s first gene-edited spider produces red fluorescent silk
For years, the CRISPR-Cas9 genome technology has been reshaping genetic engineering, a precision tool to transform everything from agriculture to medicine. With its incredible efficiency, this molecular tool has been applied to plants, animals, and even bacteria. But until now, no one has used…
Researchers at the University of Bayreuth have recently successfully bred the world’s first CRISPR-Cas9-modified spider to produce red fluorescent silk. Since many spiders are cannibalistic, with a diverse and complex genome architecture, genetic manipulation and nurturing the resulting offspring poses significant challenges. To overcome these hurdles, the researchers developed a novel CRISPR solution containing the gene sequence for a red fluorescent silk protein and injected it into unfertilized spider eggs.
