Jeeyon Jeong, Ph.D., Assistant Professor of Biology, Amherst College, will give a talk on "Navigating the Paradox of Iron: Two Tales from Plants."
Iron is an essential micronutrient in nearly all organisms, but it is also potentially toxic. Therefore, iron must be tightly controlled at the molecular, cellular, and physiological levels. Research in the Jeong Lab focuses on investigating the molecular mechanisms of iron homeostasis in plants. Our goal is to contribute critical knowledge that will advance biology and provide insights to improve plant and human nutrition.
This seminar will focus on two highlights from the Jeong Lab: 1) the characterization of Ferroportin3 (FPN3), a dual-targeted mitochondria/chloroplast iron exporter, and 2) the discovery that histone3 lysine27 trimethylation (H3K27me3) attenuates the induction of iron acquisition gene during iron deficiency.
Persons from the college community that wish to attend should please register by sending an email request to the Biology Department Chair, Professor Josef Trapani, who will provide the Zoom link.
