Ecology of Bacillaceae
TL;DR: In this review, the high functional and genetic diversity that is found within the Bacillaceae is described, their roles in ecology and in applied sciences related to agriculture are described, and questions are posed with respect to their ecological behavior.

Insufficient differentiation of live and dead Campylobacter jejuni and Listeria monocytogenes cells by ethidium monoazide (EMA) compromises EMA/real-time PCR.

TL;DR: The results suggest that EMA influences not only dead but also viable cells of C. jejuni and L. monocytogenes, and EMA/real-time PCR is a poor indicator of cell viability.

Kin discrimination between sympatric Bacillus subtilis isolates
TL;DR: Evidence of kin discrimination among micrometer-scale soil isolates of Bacillus subtilis is provided, which is reflected in striking boundaries between nonkin sympatric conspecifics during cooperative swarming on agar.

Private link between signal and response in Bacillus subtilis quorum sensing
TL;DR: By pleiotropically combining intracellular and extracellular signaling, bacteria may generate evolutionarily stable QS systems by characterizing the phenotype and fitness of comQ null mutants and showing that surfactin participates in a social selection mechanism that targets signal null mutants in coculture with signal producers.

Exploring ComQXPA quorum‐sensing diversity and biocontrol potential of Bacillus spp. isolates from tomato rhizoplane
TL;DR: The ComQXPA QS diversity among isolates from the tomato rhizoplane, a natural habitat of B. subtilis, is addressed and it is discovered that effects of surfactin deletion on biofilm formation can be strain specific and unexpected in the light of current knowledge on its role it this process.
