Phenotypic fate differentiation and its mechanism in Cronobacter sakazakii under different chlorine concentrations

Journal of Dairy Science
: Cronobacter sakazakii is a significant foodborne pathogen commonly found in dairy processing environments. Under chlorine stress, C. sakazakii may survive by adopting stress-resistant phenotypes such as biofilm and viable but nonculturable (VBNC) state.

Recent functional insights into the role of (p)ppGpp in bacterial physiology

, 2015
The alarmones guanosine tetraphosphate and guanosine pentaphosphate (collectively referred to as (p)ppGpp) are involved in regulating growth and several different stress responses in bacteria.

Arabidopsis RelA/SpoT homologs implicate (p)ppGpp in plant signaling

, 2000
Arabidopsis RPP5 is a member of a large class of pathogen resistance genes encoding nucleotide-binding sites and leucine-rich repeat domains. Yeast two-hybrid analysis showed that RPP5 specifically interacts with At-RSH1, an Arabidopsis RelA/SpoT homolog.

Biochemical characterization of Gppa-ppx homologues from Mycobacterium tuberculosis

, 2011
Inorganic polyphosphate (poly-P), guanosine pentaphosphate (pppGpp) and guanosine tetraphosphate (ppGpp) are present within all bacterial cells. These molecules play a variety of important physiological roles; especially regarding stress resistance ...

Post-translational regulation of photosynthetic activity via the TOR kinase in plants

International audienceChloroplasts are the powerhouse of the plant cell, yet they are resource-intensive and will cause photooxidative damage if their activity overshoots the demands of growth.
