Phosphate starvation in rice induces widespread, but transient, modulation of DNA methylation near stress responsive genes that is independent from the RNA-directed DNA methylation pathway.
The phosphate starvation response network in a commensal yeast evolved to expand its downstream targets via changes in the main transcription factor's dependence on its co-activator, potentially altering the physiological response.
Genetic and biochemical analysis of two enzymes reveals that inositol pyrophosphate signaling molecules allow plants to sense and regulate cellular phosphate levels, and to take up more phosphate when needed.
The transcription factor bZIP63 is a key regulator of the starvation response in the model plant Arabidopsis thaliana and is directly targeted by the kinase SnRK1.
Longevity in C. elegans is influenced not only by insulin/IGF-1 signalling, but also by CAMKII and calcineurin, acting on the same target, the transcription factor DAF-16.
Real-time 33P imaging combined with specific complementation of inorganic phosphate transport in the root cap reveals this tissue’s contribution to phosphate uptake.
Activation of the stress response pathway in young cells extends replicative lifespan, not by reducing global protein synthesis per se, but by Gcn4-mediated autophagy induction.
