Summary
June 24 marked the death of Mary-Dell Chilton at her home in Carrboro, North Carolina; her son said congestive heart failure was the cause.
Chilton helped transform Agrobacterium from a plant pathogen into a gene-delivery tool, publishing key DNA-transfer findings in 1977 and leading a team that inserted a gene into tobacco plants in 1982.
1983 brought a public breakthrough announcement and her move from Washington University in St. Louis to Ciba-Geigy, later Syngenta, where she ran a biotechnology lab until retiring in 2018.
2013 brought the World Food Prize, and colleagues credited her work with helping farmers protect crops from disease, pests and climate shocks even as GMOs continued to draw health and environmental debate.
Born in 1939, Chilton also became a model for women in science, saying she wanted to advance not because she was a woman but because she was the best.

How did the first genetically modified plant lay the groundwork for modern gene editing?
Did the pioneer of GMOs ever address the global controversies her work created?
From Lab to Field: How Mary-Dell Chilton’s Agrobacterium Breakthrough Revolutionized Global Agriculture
Overview
Dr. Mary-Dell Chilton’s discovery of Agrobacterium-mediated transformation (AMT) revolutionized plant science by enabling scientists to introduce new traits into crops. Her research revealed that Agrobacterium tumefaciens could naturally transfer DNA into plant cells. Scientists re-engineered this process, removing harmful genes and inserting beneficial ones, which allowed them to create the first genetically modified plants in 1982. This breakthrough marked a new era in agriculture, making AMT an indispensable tool in plant biotechnology and paving the way for the development of resilient, high-yield crops that address global food challenges.
