Wall teichoic acids regulate peptidoglycan synthesis to maintain rod shape in Bacillus subtilis

Nature Microbiology, Published online: 26 May 2026; doi:10.1038/s41564-026-02368-6Wall teichoic acids confer rod shape in the Gram-positive model organism Bacillus subtilis by occluding pores in the cell wall, thereby preventing runaway isotropic (non-oriented) peptidoglycan synthesis.
