(p)ppGpp mediated transcriptional changes during heat stress.
, 2020 (A/B) Global differences in gene expression in wild type versus (p)ppGpp° strains at 37 °C or 48 °C, respectively. Bar tracks indicate the distribution of genes in the respective functional groups.

Identical, independent, and opposing roles of ppGpp and DksA in Escherichia coli
, 2007 The recent discovery that the protein DksA acts as a coregulator of genes controlled by ppGpp led us to investigate the similarities and differences between the relaxed phenotype of a ppGpp-deficient mutant and the phenotype of a strain lacking DksA.

Elucidation of the role of guanosine tetraphosphate (ppGpp) in the acclimation of plants to stress
, 2023 La guanosine tetraphosphate ou ppGpp a été initialement découverte chez la bactérie Escherichia coli. Il s'agit de la molécule clé qui permet la régulation de la croissance et promeut l'acclimatation au stress des procaryotes.

Molecular mutagenesis of ppGpp : turning a RelA activator into an inhibitor
, 2017 The alarmone nucleotide (p) ppGpp is a key regulator of bacterial metabolism, growth, stress tolerance and virulence, making (p) ppGpp-mediated signaling a promising target for development of antibacterials.

Role of (p)ppGpp in biofilm formation by E. faecalis.
, 2011 Enterococcus faecalis strain OG1RF and its (p)ppGpp-deficient mutants ΔrelA, ΔrelQ and ΔrelAΔrelQ were grown in biofilms and evaluated for growth profiles, biofilm morphology, cell viability, and proteolytic activity. E.

The Physiological Significance of (p)ppGpp in Enterococcus faecalis
Thesis (Ph.D.)--University of Rochester. School of Medicine & Dentistry. Dept. of Microbiology, Immunology and Virology, 2014.The stringent response (SR) is a conserved stress response in bacteria that shifts cells from a growth mode to a survival mode.
