Protein function
Encodes a bHLH transcription factor.
Phenotype
Multiple mutant: pif4;
pif5 multiple mutant is late flowering under 12h-light-12h-dark photoperiod at any temperature, even though the phenotype is enhanced at high temperatures. (No data under SD or LD conditions.)
[Thines et al., 2014] Single mutant: pif5 single mutant is late flowering under 28C-warm conditions and 12h-light - 12h-dark photoperiod. (No data under SD or LD conditions.)
[Thines et al., 2014] Remarks: PIF5 acts negatively in the PHYB signaling pathway.
[Khanna et al., 2007] Function:Transcription factor acting negatively in the phytochrome B signaling pathway to promote the shade-avoidance response. Regulates PHYB abundance at the post-transcriptional level, possibly via the ubiquitin-proteasome pathway. Promotes ethylene activity in the dark. May regulate the expression of a subset of genes by binding to the G-box motif. Might be involved in the integration of light-signals to control both circadian and photomorphogenic processes.
