kinD is necessary for some but not all interspecies interactions leading to induction of B. subtilis matrix production and cannibalism. Inducing organisms were tested for their ability to activate the Pskf-yfp reporter in wild-type and kinase deletion mutants of B. subtilis using the secondary screen format. (A) B. megaterium and B. cereus have reduced activation of the Pskf-yfp reporter in the absence of kinD. (B) B. vallismortis and B. atrophaeus do not require any of the sensor kinases for induction of the Pskf-yfp fluorescent reporter.
