GDCB Seminar - R. Keith Slotkin

Tuesday, August 29, 2017 - 4:10pm
Event Type: 

The Department of Genetics, Development and Cell Biology Seminar for Tuesday, Aug. 29, will feature Dr. R. Keith Slotkin of The Ohio State University. He will present “Establishment of Heterochromatin: Transposons and Trans-Generational Silencing” at 4:10 p.m. in Room 1414 of the Molecular Biology Building.

Dr. Slotkin is an associate professor in the Department of Molecular Genetics and director of the Arabidopsis Biological Resource Center (ABRC).

Refreshments will be served before the seminar at 3:45 p.m.  Professor Erik Vollbrecht is hosting Dr. Slotkin’s visit.


How does the cell know which regions of its genome should be transcribed (such as genes) and which should not (such as transposable elements)? The Slotkin laboratory investigates the epigenetic regulation of transposable elements (TEs) in the reference plant Arabidopsis. Our emphasis is on determining how the cell recognizes a new or active TE, how it deciphers the TE from an active gene, and how TE silencing is initiated, established and epigenetically maintained. Research has focused on two core projects: 1) the small RNA-directed chromatin modification mechanisms responsible for the initiation of epigenetic silencing, and 2) how germ cells and their neighboring nurse cells communicate to ensure that TEs are epigenetically marked and silenced from the very first cell of the next generation.
