In mammals, gluconeogenesis takes place mainly in the liver, and to a lesser extent in renal cortex and in the epithelial cells that line the inside of the small intestine.

The phyB mutants are deficient in chlorophyll

phyB also appears to regulate LFRs, such as photoreversible seed germination

Mutants that lack phyA respond normally to red light, whereas mutants deficient in phyB are unable to respond to low-fluence red light

Phytochrome interacting factors (PIFs) are a family of proteins that act primarily as negative regulators of photomorphogenic responses.

PIFs promote etiolated development in the dark (skotomorphogenesis) primarily by serving as transcriptional activators of dark induced genes

Red light-induced Pfr formation initiates the degradation of PIF proteins through phosphorylation, followed by degradation via the proteasome complex
