Summary
June 24 marked the death of Mary-Dell Chilton at 87 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 the team credited with the first genetically modified plant in 1982.
January 1983 brought public confirmation of that breakthrough, when her group reported inserting a gene into a tobacco plant alongside rival teams from Belgium and Monsanto.
Her work fueled modern agricultural biotechnology, earned the 2013 World Food Prize and the National Medal of Technology and Innovation, and underpinned crops designed to resist disease, pests and climate shocks.

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.
