Rate My Professor Melissa Mitchum

Melissa G. Mitchum serves as the Barry Bustillo Distinguished Professor of Plant Nematology in the Department of Plant Pathology, Center for Applied Genetic Technologies, and Institute of Plant Breeding, Genetics and Genomics at the University of Georgia. Her research centers on molecular plant-nematode interactions, with a particular emphasis on sedentary endoparasitic cyst nematodes, including Heterodera glycines (soybean cyst nematode), and root-knot nematodes such as Meloidogyne incognita and Meloidogyne hapla. She investigates nematode effector proteins secreted via the stylet that mimic plant peptide hormones, manipulate host gene expression, and reprogram plant cell development to form specialized feeding sites essential for nematode parasitism. Mitchum's work also explores host plant resistance mechanisms, including the identification of candidate genes at the Rmi1 locus for resistance to southern root-knot nematode in soybean and the role of GmSNAP14 in soybean cyst nematode compatibility.

Mitchum obtained her B.S. in Biology from the University of Puget Sound in 1993, M.S. in Plant Pathology from the University of Nebraska in 1995, Ph.D. in Plant Pathology with a minor in Biotechnology from North Carolina State University in 2001, and completed a postdoctoral fellowship in the Developmental, Cell, and Molecular Biology Group at Duke University in 2003. She held previous academic appointments at the University of Missouri before joining the University of Georgia, where she was named to the Barry Bustillo Distinguished Professorship in Plant Nematology in 2025. Her contributions have earned her election as a Fellow of the American Association for the Advancement of Science in 2024 for advancements in understanding plant-nematode interactions. With over 9,800 citations on Google Scholar, key publications include 'Nematode effector proteins: an emerging paradigm of parasitism' (New Phytologist, 2013), 'Phytoparasitic Nematode Control of Plant Hormone Pathways' (Plant Physiology, 2019), 'Identification of a stylet-secreted effector protein family as peptide hormone mimics in plants' (PNAS, 2026), and 'Candidate genes at the Rmi1 locus for resistance to Meloidogyne incognita in soybean' (Theoretical and Applied Genetics, 2025). She co-directs a $1.2 million NSF-NIFA Plant Bioproduction Initiative award to develop novel strategies against soybean cyst nematode and contributes to soybean performance tests evaluating nematode resistance.
