Gene : LFY A. thaliana

Gene ID  ? AT5G61850
Brief Description  floral meristem identity control protein LEAFY (LFY)  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? LEAFY (LFY); CONTAINS InterPro DOMAIN/s: Floricaula/leafy protein (InterPro:IPR002910).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? Encodes transcriptional regulator that promotes the transition to flowering.Involved in floral meristem development. LFY is involved in the regulation of AP3 expression, and appears to bring the F-box protein UFO to the AP3 promoter. Amino acids 46-120 define a protein domain that mediates self-interaction.  Source: TAIR, Jun 30, 2015.
Name  ? LEAFY

LFY and AGL15 are involved in the regulation of AtMYB17 in early inflorescence development and seed germination. 19232308
Data show that LEAFY, FRUITFULL, and APETALA1 are directly activated by the microRNA-targeted transcription factor SQUAMOSA PROMOTER BINDING PROTEIN-LIKE 3 (SPL3) to control the timing of flower formation. 19686687
The motif analyses reveal a possible mechanism for stage-specific LFY recruitment and suggest a role for LFY in overcoming polycomb repression. 21497757
A biophysical model describing LFY DNA binding specificity in vitro was built that accurately predicts in vivo LFY binding sites in the Arabidopsis thaliana genome. 21515819
LEAFY binding site is essential for proper photoperiodic activation of APETALA1 21623976
Data show that the direct LEAFY target LATE MERISTEM IDENTITY2 (LMI2) has a role in the meristem identity transition, and acts together with LEAFY to activate APETALA1. 21750030
LFY activity affects adaxial pedicel identity and cell elongation. LFY mutation suppresses the crm1 pedicel length and orientation phenotypes. 22050454
The SWI2/SNF2 ATPases physically interact with two direct transcriptional activators of class B and class C gene expression, LEAFY (LFY) and SEPALLATA3 (SEP3). 22323601
Studies indicate that LEAFY is a master regulator of flowering. 22451042
must act in complexes that contain at least two LFY molecules; the N-terminus is essential for stabilization 22507399
these three transcription factors LFY, ANT and AIL6/PLT3 are redundantly required for flower primordium initiation. 23375585
A LFY allele with reduced floral function revealed its ability to stimulate axillary meristem growth. This role requires the ability of LFY to bind DNA, and is mediated by direct induction of REGULATOR OF AXILLARY MERISTEMS1 (RAX1) by LFY. 23445516
LEAFY controls auxin response pathways in floral primordium formation. 23572147
The ULT1 and LFY pathways act separately in regulating identity and determinacy at the floral meristem. In particular, they independently induce AG expression in the centre of the flower to terminate meristem activity. 25288633
Data suggest that helix-turn-helix transcription factor LEAFY (LFY) and the MADS box transcription factor APETALA1 (AP1)together orchestrate the switch to flower formation and morphogenesis by altering transcriptional programs. 26096587
