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.

Mary Lou Guerinot的个人资料。

在1970年4月22日的第一个地球日，玛丽·楼·圭里诺特（Mary Lou Guerinot）决定，她将在大学主修生物学，以期促进环境的可持续发展。随着地球日诞辰50周年的到来，现任达特茅斯学院生物科学教授，美国国家科学院院士的格里诺（Guerinot）正在努力通过实现金属离子吸收的分子机制来实现这一目标及其法规。Guerinot的工作为环境可持续，营养密集的农作物以及从土壤中去除有毒金属的基于植物的解决方案奠定了基础。她的就职演说（1）报告了铁缺乏条件下植物生长必需的转录因子的鉴定。这一发现使她的团队更加了解植物中的铁稳态途径，从而有望提高农业生产力和人类健康。
