Phenotypes of a mutant
- SigM is essential for growth and survival in nutrient broth (NB) containing 1.4 M NaCl PubMed
- sigM mutants form aberrantly shaped cells, which swell and lyse spontaneously during growth in NB medium containing increased levels (0.35-0.7 M) of a wide range of different salts PubMed
