Summary

Go to the top of the page Help

Gene symbol: FD
Gene description: Basic-leucine zipper (bZIP) transcription factor family protein
Primary source: Araport:AT4G35900
Locus tag: AT4G35900
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: atbzip14; FD-1; T19K4.30
Summary: bZIP protein required for positive regulation of flowering. Mutants are late flowering. FD interacts with FT to promote flowering.Expressed in the shoot apex in floral anlagen, then declines in floral primordia.

What's a GeneRIF?

FD is a central regulator of floral transition at the shoot meristem.FD phosphorylation is required for complex formation and to promote flowering.
Title: FT Modulates Genome-Wide DNA-Binding of the bZIP Transcription Factor FD.
This work therefore identifies a new role for FD in reproductive patterning, as FD regulates IM function together with HDA19 in an age-dependent fashion.
Title: HISTONE DEACETYLASE 19 and the flowering time gene FD maintain reproductive meristem identity in an age-dependent manner.
AcMFT from a non-flowering plant could interact with FD to regulate the floral transition and that this function was reduced due to the weakened ability of AcMFT-FD to activate the downstream gene AP1.
Title: Comparative analysis of the pteridophyte Adiantum MFT ortholog reveals the specificity of combined FT/MFT C and N terminal interaction with FD for the regulation of the downstream gene AP1.
(CPK6 and CPK33) are expressed in shoot apical meristem and directly interact with FD, suggesting they have redundant functions
Title: Calcium-dependent protein kinases responsible for the phosphorylation of a bZIP transcription factor FD crucial for the florigen complex formation.
Floral repressor BFT delays flowering by competing with FT for FD binding under high salinity.
Title: The Arabidopsis floral repressor BFT delays flowering by competing with FT for FD binding under high salinity.
the early flowering allele of FLH requires the floral integrator FD to accelerate flowering.
Title: Acceleration of flowering in Arabidopsis thaliana by Cape Verde Islands alleles of FLOWERING H is dependent on the floral promoter FD.
The specification of flower and inflorescence meristems requires the combined activities of FT-FD and STM.
Title: Specification of reproductive meristems requires the combined function of SHOOT MERISTEMLESS and floral integrators FLOWERING LOCUS T and FD during Arabidopsis inflorescence development.
a complex of FT and FD proteins in turn can activate floral identity genes such as APETALA1
Title: Integration of spatial and temporal information during floral induction in Arabidopsis.
FD, preferentially expressed in the shoot apex required for FT to promote flowering
Title: FD, a bZIP protein mediating signals from the floral pathway integrator FT at the shoot apex.
