Patrick MassonView profile
Professor
Patrick Masson is a Professor in the Genetics Department at the University of Wisconsin–Madison, where he leads an active research laboratory focused on plant root growth behaviors and molecular mechanisms of gravitropism. His work primarily utilizes Arabidopsis thaliana and Brachypodium distachyon as model systems to investigate how roots respond to environmental stimuli. Position: Professor Department: Genetics University: University of Wisconsin–Madison Lab Website: http://masson.genetics.wisc.edu/ Dr. Masson received his Ph.D. from Faculté des Sciences Agronomiques de l'état, Gembloux, Belgium (1986), followed by postdoctoral research at the Department of Embryology, Carnegie Institution of Washington, Baltimore (1986-1991). His research focuses on understanding the molecular mechanisms that allow roots to adopt specific growth behaviors in response to environmental parameters including gravity, light, touch, and chemical gradients. A significant portion of his work investigates the role of polyamines, particularly cadaverine, in regulating root growth behavior and root system architecture development in response to biotic and abiotic stressors. His laboratory employs molecular genetic strategies to study gravity-induced cytoplasmic alkalinization, lateral auxin transport, and other complex root growth phenomena. Analysis of his recent publications reveals a strong focus on root gravitropism, with increasing attention to space biology applications as evidenced by studies conducted on the International Space Station. His work spans from fundamental molecular mechanisms to applied research using advanced techniques like clinorotation to simulate microgravity conditions. The research consistently bridges plant physiology, molecular genetics, and biochemical approaches to understand root behavior. Dr. Masson currently mentors several graduate students and researchers, including Marie Keith, Dorian Alexander Buening, and Shih-Heng Su, who contribute to ongoing projects investigating root tip circumnutation in Brachypodium distachyon and the molecular basis of the Cadaverine Effect. His laboratory utilizes a range of tools including genetics, molecular biology, biochemistry, microscopy, and time-lapse photography to advance understanding of plant root growth behaviors.
