Mary-Dell Chilton Dies at 87; Helped Create First Genetically Modified Plant

Mary-Dell Chilton, the plant scientist whose work helped open the door to genetically modified crops, has died at 87, according to a report from The New York Times Technology.

Chilton was a central figure in a breakthrough that changed modern agriculture. In 1982, she led a research team that discovered how to genetically alter plants, a milestone that later helped make possible a wave of crop engineering around the world. Her work is widely regarded as foundational to the development of genetically modified plants.

The achievement placed Chilton among the most influential scientists in agricultural biotechnology. By showing that plant genetics could be deliberately altered, her team helped establish methods that would eventually be used in efforts to improve crop resilience, productivity and other traits. The discovery became part of a broader scientific shift that transformed how researchers approached agriculture.

The report, based on a monitored public feed, identifies Chilton as the scientist behind the landmark research and notes her death at 87. No additional details were provided in the feed summary.

Chilton’s legacy rests on the long reach of that early work. What began in a laboratory in 1982 went on to shape an industry and influence farming practices across the globe. For decades, the ability to modify plants at the genetic level has remained one of the most consequential advances in agricultural science.
