The paper shows that non-motile Bacillus subtilis mutants evolve matrix overproducers with a wrinkly phenotype due to SinR mutations, which enhance exopolysaccharide production and biofilm formation in the absence of flagella.

This study shows that genetic division of labor in Bacillus subtilis enhances biofilm productivity by allowing specialized mutants to exchange matrix components, outperforming phenotypic specialization.

This study shows how Bacillus subtilis biofilms evolve into distinct colony variants with different biofilm-forming abilities and interactions, driven by genetic changes and complementarity effects.

This study shows that flagellar mutants of Bacillus subtilis have reduced competence due to decreased comK expression, linked to increased phosphorylated DegU.

This paper identifies Lysinibacillus fusiformis M5 as a soil bacterium that induces wrinkle formation in Bacillus subtilis biofilms via hypoxanthine, showing it does not rely on known biofilm regulators.
