Flagellar toxicity: flagellar synthesis is lytic for Bacillus subtilis in the absence of PBP1

Caroline M. Dunn, Kehinde Oreoluwa Adebiyi, Daniel B. Kearns

This study shows that flagellar synthesis in Bacillus subtilis causes cell lysis when PBP1 is absent, due to activation of peptidoglycan hydrolases via SigD.

Nascent flagellar basal bodies are immobilized by rod assembly in Bacillus subtilis

Caroline M. Dunn, Daniel J. Foust, Yongqiang Gao…·Daniel B. Kearns

The paper shows that basal bodies in Bacillus subtilis are mobile during early assembly and become immobilized when the rod transits the peptidoglycan, suggesting rod polymerization probes the peptidoglycan for pores.
