Multigenerational memory in bacterial size control
Motasem ElGamel, Harsh Vashistha, Hanna Salman +1
Cells maintain a stable size as they grow and divide. Inspired by the available experimental data, most proposed models for size homeostasis assume size control mechanisms that act…
Non-genetic inheritance restraint of cell-to-cell variation
Harsh Vashistha, Maryam Kohram, Hanna Salman
Heterogeneity in physical and functional characteristics of cells (e.g. size, cycle time, growth rate, protein concentration) proliferates within an isogenic population due to stoc…
Individuality and slow dynamics in bacterial growth homeostasis
Lee Susman, Maryam Kohram, Harsh Vashistha +3
Microbial growth and division are fundamental processes relevant to many areas of life science. Of particular interest are homeostasis mechanisms, which buffer growth and division…
Interactions of Solitary Pulses of E. coli in a One-Dimensional Nutrient Gradient
Glenn Young, Mahmut Demir, Hanna Salman +2
We study an anomalous behavior observed in interacting E. coli populations. When two populations of E. coli are placed on opposite ends of a long channel with a supply of nutrient…
Statistical properties and dynamics of phenotype components in individual bacteria
Lee Susman, Maryam Kohram, Harsh Vashistha +3
Cellular phenotype is characterized by different components such as cell size, protein content and cell cycle time. These are global variables that are the outcome of multiple inte…
Distributed Gradient Descent in Bacterial Food Search
Shashank Singh, Sabrina Rashid, Zhicheng Long +4
Communication and coordination play a major role in the ability of bacterial cells to adapt to ever changing environments and conditions. Recent work has shown that such coordinati…
Universal Protein Distributions in a Model of Cell Growth and Division
Naama Brenner, C. M. Newman, Dino Osmanovic +3
Protein distributions measured under a broad set of conditions in bacteria and yeast were shown to exhibit a common skewed shape, with variances depending quadratically on means. F…
Single-cell protein dynamics reproduce universal fluctuations in cell populations
Naama Brenner, Erez Braun, Anna Yoney +3
Protein variability in single cells has been studied extensively in populations, but little is known about temporal protein fluctuations in a single cell over extended times. We pr…
Universal protein fluctuations in populations of microorganisms
Hanna Salman, Naama Brenner, Chih-kuan Tung +5
The copy number of any protein fluctuates among cells in a population; characterizing and understanding these fluctuations is a fundamental problem in biophysics. We show here that…
