A starvation-induced drop in cytosolic pH promotes assembly of budding yeast glutamine synthetase into enzymatically inactive filaments that function as enzyme storage depots.
A reconstituted system has been developed that self-organizes into dynamic actin cortices capable of spontaneous polarization, similar to the initial cortical polarization observed in cells during embryogenesis and development.

In the Arabidopsis epidermis, the internal mechanical stress of a cell competes with the external stress to control microtubule behavior, providing a framework to understand the mechanical feedbacks that underlie plant morphogenesis.
In vitro reconstitution of mRNA motility reveals the basis of directionally biased motion by groups of motors, their response to potential obstacles, and the consequences of reaching microtubule ends.
