Regulation of Mycobacterial Growth

Mycobacteria are phylogenetically distinct from the model organisms classically used to study prokaryotic cell biology. Consequently, the mechanisms controlling the growth, division, and morphogenesis of the mycobacterial cell are unique to this genus. We are using genetics, time-lapse microscopy, and high-throughput image-based screening to understand the mechanisms regulating these processes (for more information see a commentary on our work ).
