Professor, School of Integrative Plant Science Plant Biology Section
June Nasrallah is Barbara McClintock Professor in the Plant Biology Section of the School of Integrative Plant Science. She received a B.Sc. degree in Biology at the American University of Beirut, Lebanon and a Ph.D. in Genetics at Cornell University. She is a member of the graduate fields of Plant Biology, Genetics and Development, and Biochemistry, Molecular, and Cell Biology.
Receptor-ligand interactions and cell-cell signaling
Our research is aimed at deciphering the molecular mechanisms underlying the highly specific pollen-stigma interactions that ultimately lead either to successful pollination and seed production or to inhibition of pollen tube growth and failure to set seed. Out-crossing and self-fertilizing members of the Brassicaceae family, including the model plant Arabidopsis thaliana and its close relatives, are used for mechanistic studies of receptor/ligand-based pollination responses and for understanding the evolution of mating systems.
