Summary
June 24 marked the death of Mary-Dell Chilton at 87 at her home in Carrboro, North Carolina, from congestive heart failure, her son Mark confirmed.
Chilton helped transform agrobacterium from a plant pathogen into a gene-delivery tool, publishing key 1977 findings and then leading the team that created the first genetically modified plant in 1982.
1983 brought a wider biotechnology race: at a conference, her group announced a gene inserted into tobacco as Belgian and Monsanto teams reported similar breakthroughs, helping launch modern agricultural biotech.
2013 recognition came with the World Food Prize, shared with Marc Van Montagu and Robert Fraley, after a career that later included leading a Syngenta biotechnology lab until her 2018 retirement.
Her work expanded crop protection against disease, pests and climate shocks while also helping usher in GMO debates over health, environment and the role of engineered crops in climate adaptation.

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.
