What if we could boost crop yields—not by adding foreign genes, but by tweaking the plant’s own DNA in just the right places? For decades, plant scientists have known that the noncoding DNA flanking a gene—its promoter and regulatory regions—acts like a volume dial, controlling how much protein the gene produces. Adjusting that dial is […] The post Tiny Edits, Big Harvests: How a Massive Mutation Screen Could Transform Crop Engineering appeared first on Promega Connections .
