Protein function
Encodes a DNA binding protein that bind AT-rich regions in vitro.
Phenotype
RNA interference: ahl18;
ahl22;
ahl27;
ahl28 multiple RNAi knockdown transgenic line is early flowering under both SD and LD conditions.
[Xiao et al., 2009] Overexpressor: AHL22 overexpressor is late flowering under LD conditions.
[Xiao et al., 2009][Yun et al., 2012] Function:Transcription factor that specifically binds AT-rich DNA sequences related to the nuclear matrix attachment regions (MARs). Binds an AT-rich DNA sequences in the FLOWERING LOCUS T (FT) promoter (PubMed:22442143). Acts redundantly with AHL18, AHL27 and AHL29 in the regulation of flowering and regulation of the hypocotyl elongation. Plays a role in both photo- and skotomorphogenesis (PubMed:19517252). Acts as a chromatin remodeling factor that modifies the architecture of FLOWERING LOCUS T (FT) chromatin by modulating both H3 acetylation and methylation leading to the regulation of FT expression during flowering induction (PubMed:22442143).
