Biological, Environmental, & Climate Sciences (BECS) Department Seminar

"Plant Systems Biology: From Predictive Network Modeling to Trait Evolution"

Presented by Gloria M. Coruzzi, Department of Biology, Center for Genomics & Systems Biology, New York University, New York, NY

Friday, November 7, 2014, 11:00 am — John Dunn Seminar Room, Bldg. 463

Main Research Interests — Dr. Coruzzi's lab initiated systems biology approaches in Arabidopsis and other species to study gene regulatory networks. Using network integration and machine-learning approaches, her lab generated the first dynamic and predictive regulatory networks in plants, a hallmark of Systems Biology. These networks uncovered novel hypotheses including nutrient control of the clock, and a Hit-and-Run transcription model. These informatic tools are embodied in a systems-biology enabling software platform VirtualPlantv1.3 (, developed with NYU's Courant Inst. of Mathematical Sci. Dr. Coruzzi also leads a collaborative NSF Plant Genome Project - "Comparative Genomics of Seed Evolution" with co-PIs at the NY Botanical Garden, the American Museum of Natural History, and CSHL. This generated the largest genome-scale phylogeny of 150 seed plants, the BigPlantv1.0 matrix ( available as an interactive browser, "PhyloBrowser." This resource enables researchers to explore the genomic underpinnings of plant diversification across a wide range of species.
