On the first Earth Day, April 22, 1970, Mary Lou Guerinot decided that she would major in biology in college in the hope of promoting environmental sustainability. As the 50th anniversary of Earth Day approaches, Guerinot, now a professor of biological sciences at Dartmouth College and a member of the National Academy of Sciences, is well on her way toward achieving that goal through her work on the molecular mechanisms of metal ion uptake and its regulation. Guerinot’s work is laying the foundation for environmentally sustainable, nutrient-dense crops, as well as plant-based solutions for removal of toxic metals from soil. Her Inaugural Article (1) reports the identification of a transcription factor essential for plant growth under iron deficiency. The finding moves her team closer to understanding the iron homeostasis pathway in plants, holding promise for improving agricultural productivity and human health.
