The amino group at C-2 bears a fatty acid in amide linkage.

The fatty acid is usually saturated or monounsaturated, with 16, 18, 22, or 24 carbon atoms.

Ceramide is the parent compound for this group.

Mutants lacking phyA also failed to germinate in response to millisecond pulses of light, but showed a normal response to red light in the low-fluence range. Means pfr primarily receives VLFR

phyC, phyD, and phyE appear to play roles that are for the most part redundant with those of phyA and phyB. Whereas phyB appears to be involved in regulating all stages of development

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.
