Phase transitions during fruiting body formation in Myxococcus xanthus
Shashi Thutupalli, Mingzhai Sun, Filiz Bunyak +2
The formation of a collectively moving group benefits individuals within a population in a variety of ways such as ultra-sensitivity to perturbation, collective modes of feeding, a…
Myxococcus xanthus gliding motors are elastically coupled to the substrate as predicted by the focal adhesion model of gliding motility
Rajesh Balagam, Douglas B. Litwin, Fabian Czerwinski +4
Myxococcus xanthus is a model organism for studying bacterial social behaviors due to its ability to form complex multi-cellular structures. Knowledge of M. xanthus surface gliding…
Efficient Multiple Object Tracking Using Mutually Repulsive Active Membranes
Yi Deng, Philip Coen, Mingzhai Sun +1
Studies of social and group behavior in interacting organisms require high-throughput analysis of the motion of a large number of individual subjects. Computer vision techniques of…
Direct measurement of cell wall stress-stiffening and turgor pressure in live bacterial cells
Yi Deng, Mingzhai Sun, Joshua W. Shaevitz
We study intact and bulging Escherichia coli cells using atomic force microscopy to separate the contributions of the cell wall and turgor pressure to the overall cell stiffness. W…
