SUMMARY:Physics-Biology interface seminar: Shiladitya Banerjee - Moyen Amph
 i\, Building 510\, Université Paris-Saclay Orsay - 24 Jan 18 11:00
DESCRIPTION:Adaptive division control in stressed bacterial cells\nShiladit
 ya Banerjee (UCL\, UK)\n\nControl of cell size is a fundamental adaptive t
 rait that underlies the coupling between cell growth and division. Cells p
 ossess the unique ability to adapt their size and shapes in response to en
 vironmental cues\, thereby translating extracellular information into deci
 sions to grow or divide. However\, the physical mechanisms mediating the r
 egulation of cell size and division timing remain poorly understood. In th
 is talk\, I will discuss our recent discovery of an adaptive model of cell
  size control in bacteria\, where the decision to divide is tightly regula
 ted by the spatial patterning of cell wall growth modes. Using a combinati
 on of stochastic mechanical modelling and single-cell experiments\, I will
  elucidate the implications of the size control model for cellular fitness
  adaptation under stress. In particular\, our results show that morphologi
 cal transformations provide fitness and survival advantages to bacteria un
 der sustained antibiotic treatment.\n
