In bacteria, algae, fungi, and plant cells, the wall must expand in concert with cytoplasmic biomass production, otherwise cells would experience toxic molecular crowding 1,2 or lyse. But how cells achieve expansion of this complex biomaterial in coordination with biosynthesis of macromolecules in the cytoplasm remains unexplained 3 , although recent works have revealed that these processes are indeed coupled 4,5 . Here, we report a striking increase of turgor pressure with growth rate in E. coli , suggesting that the speed of cell wall expansion is controlled via turgor...
