A new CRISPR-driven technology for gene drive in plants

Weeds are a pesky irritant for most home gardeners, but in large agricultural settings, weeds can pose an especially deadly problem. For example, Amaranthus palmeri, known as Palmer's pigweed, has evolved in many areas to be completely resistant to modern herbicides, enabling it to take over fields of corn, soybeans, and other important crops. To make pigweed susceptible to herbicides again, you would need to change its genetics.
