TezRs regulate biofilm morphology and cell size. Morphology of nuclease-treated or control 72-h-old biofilms. (A) Control B. pumilus. (B) B. pumilus TezR–D1^d. (C) B. pumilus TezR–R1^d. (D) B. pumilus TezR–D1^d/R1^d. (E) B. pumilus TezR–D2^d. (F) B. pumilus TezR–R2^d. (G) B. pumilus TezR–D2^d/R2^d. (H) B. pumilus TezR–D1^d/D2^d. (I) B. pumilus TezR–D1^d/R1^d/D2^d/R2^d. Scale bars indicate 5 or 10 mm. Representative images of three independent experiments are shown. (J). Cell length of bacteria grown on solid medium (µm). *p < 0.05, ***p < 0.001. Data represent the mean ± SD from three independent experiments
