TL;DR: The transcriptomes of Bacillus subtilis exposed to a wide range of environmental and nutritional conditions that the organism might encounter in nature are reported, offering an initial understanding of why certain regulatory strategies may be favored during evolution of dynamic control systems.

TL;DR: The responses of a bacterium to changing nutritional conditions are explored and an initial understanding of why certain regulatory strategies may be favored during evolution of dynamic control systems is offered.

TL;DR: Bacterial serine/threonine and tyrosine kinases probably engage in a network-type behavior previously described only in eukaryal cells, and cross-phosphorylation events are very likely to influence the capacity of recipient kinases to phosphorylate substrates downstream in the signal transduction cascade.

TL;DR: It is shown that persistent RecA foci, which presumably coincide with irreparable lesions, are mutually exclusive with the completion of spore morphogenesis and highlight similarities between the bacterial serine/threonine kinase YabT and eukaryal kinases C‐Abl and Mec1, which are also activated by DNA, and phosphorylate proteins involved in DNA damage repair.

TL;DR: This study highlighted the role of tyrosine and serine/threonine kinases and phosphatases in DNA metabolism, transcriptional control and cell division and revealed significant crosstalk among different classes of kinases.
