Phenotypes of a mutant
Inactivation of ''[gene|8BA7714236EBFDBB9987F1DACC9775AD974C743E|alsR]'', ''[gene|7024E4162A6D827069F882FDEACA696EBC05DD40|sigD]'' and ''[gene|3D974DD2967C7F8FD4E3C2AF42617B8AE9F0296D|sigW]'' increases competitive fitness of ''Bacillus subtilis'' under non-sporulating conditions [Pubmed|22344650]
mucoid phenotype due to the overproduction of poly-gamma-glutamate (because of the loss of ''[gene|86C729C7D5ABEE519ADC4A893940600BBB655EF1|motA]-[gene|FE56753D061344B0F10A6523F49C5C7356AA40B6|motB]'' expression) [Pubmed|24296669]
not essential for pellicle biofilm formation, but mutant is outcompeted by the wild-type strain when competed during pellicle formation [Pubmed|26122431]
defective in [category|SW.4.1.4|Swarming] motility [pubmed|35638827]
