ppGpp synthesis ,degradation and turnover
"The basal level of ppGpp in NF162 (RC-) is about 0.04 nmole per OD unit (ref 36)."
"the high level of RpoS in one laboratory strain (MC4100) was partially dependent on an elevated basal level of ppGpp, an alarmone responding to stress and starvation. The elevated ppGpp was caused by two mutations in spoT"

Indution of stringent response
The stringent response can be inducted by several methods, which increase levels of (p)ppGpp either directly or indirectly.
- Overexpression of ppGpp synthetase (ex. RelA, RelSeq).
- Valine treatmet (E. coli K-12)

From the introduction: "When Escherichia coli cells are deprived of an essential amino acid (1,2) or are unable to activate one (3) there ensues a comprehensive adjustment of cellular activity termed the "stringent" response."
References 1,2 and 3 are [Sands & Robers 1952 J Bacteriol 63, 505], [Pardee and Prestidge LS 1956 J Bacteriol 71, 677] and [Neidhardt FC 1966 Bacteriol Rev 30, 701], respectively.

Several articles list this as their reference for the term "Stringent response". The term as quoted does not appear in the article. However, the following quote establishes the "RC" locus nomenclature:
"The amino acid-independent RNA synthesis in this recombinant shows that there must exist a chromosomal locus, which we shall call RC, that in its RCrel allelic state of the 58-161 donor line produces less stringent, i.e., "relaxed," amino acid control of RNA synthesis than its RCSt, or "stringent," allele of the F- recipient line."

The first chronological hit for the search term "Stringent response" in Google Scholar is the article "Effects of amino acid starvation upon constitutive tryptophan messenger RNA synthesis". John D. Stubbs†, Benjamin D. Hall. Journal of Molecular Biology Volume 37, Issue 2, 28 October 1968, Pages 303–312
It contains the quote " Stent & Brenner (1961) found quantitative variations in the stringent response depending upon the amino acid withheld.".
