Environmental Microbiology, Volume 22, Issue 6, Page 2312-2328, June 2020., 2020 Summary Upon competence‐inducing nutrient‐limited conditions, only part of the Bacillus subtilis population becomes competent. Here, we separated the two subpopulations by fluorescence‐assisted cell sorting (FACS). Using RNA‐seq, we confirmed the previously described ComK regulon.
