In B. subtilis, it is the elongation itself that is controlled by (p)ppGpp because the replication forks are arrested during the stringent response. This arrest is caused by direct inhibition of the primase by (p)ppGpp, arresting the replication fork at any location when the stringent response occurs. Citation: Bouveret E, Battesti A. 2011.

This arrest is caused by direct inhibition of the primase by (p)ppGpp, arresting the replication fork at any location when the stringent response occurs. Citation: Bouveret E, Battesti A. 2011. In 1969, Cashel and Gallant first observed the presence of (p)ppGpp—the signaling molecule of the stringent response—in starved bacterial cells. Fifty years later, (p)ppGpp and the stringent response have emerged as essential master regulators of not only the bacterial response to stress but also almost all aspects of bacterial physiology, virulence, and immune evasion. 2019-07-01 The stringent response is a key regulatory reaction exhibited by bacteria in response to amino acid deprivation or carbon, nitrogen and phosphate limitation.

Although nutritional stress is common for rhizobia while infecting This is a composite measure based on nine response indicators including school closures, workplace closures, and travel bans, rescaled to a value from 0 to 100 (100 = strictest).

Stringent response

The stringent response is a conserved global stress response in bacteria that involves the production of the hyperphosphorylated guanine nucleotides ppGpp and pppGpp (collectively called (p)ppGpp). (p)ppGpp then regulates a number of cellular processes to adjust the physiology of the bacteria to promote survival in different environments. 2008-12-12 · Author Summary Management of cell growth and division in response to environmental conditions is important for all cells.

The hallmark of stringent response is  GO:0015968 JSON. stringent response. Biological Process.

AB - Current research is primarily focused on compositional shifts and alterations in the metabolic status of the gut microbiota to elucidate the damage caused by antibiotics. Nutritional stress elicits stringent response in bacteria involving modulation of expression of several genes. This is mainly triggered by the intracellular accumulation of two small molecules, namely, guanosine 3'-diphosphate 5'-triphosphate and guanosine 3',5' … Stringent complete response (sCR) criteria are used in multiple myeloma as a deeper response category compared with CR, but prospective validation is lacking, it is not always clear how evaluation of clonality is performed, and is it not known what the relative clinical influence is of the serum free light chain ratio (sFLCr) and bone marrow (BM) clonality to define more sCR. The stringent response', also called stringent control, is a stress response of bacteria and plant chloroplasts in reaction to amino-acid starvation, fatty acid limitation, iron limitation, heat shock and other stress conditions.

Genetic components of stringent response in Vibrio cholerae. The stringent response is one of such gene regulatory mechanisms which is stimulated by nutrient starvation. It is regulated by the synthesis of highly phosphorylated signaling nucleotides, (p)ppGpp or alarmone. (p)ppGpp is synthesized by ppGpp synthetases, and these proteins are classified as RelA/SpoT homolog (RSH) proteins.
