RT   flowering and controls FT-like gene expression independently of Hd1.";
RL   Genes Dev. 18:926-936(2004).
CC   -!- FUNCTION: Transcriptional activator that acts as floral inducer to
CC       promote short-day (SD) flowering pathway. Activates Hd3a and other FT-
CC       like genes independently from Hd1. May also activate MADS-box
CC       transcription factors involved in flowering regulation.

CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00625}.
CC   -!- INDUCTION: Daily oscillation and diurnal expression in plants grown in
CC       short day (SD) but not in long day (LD) conditions.
CC       {ECO:0000269|PubMed:15078816}.
CC   -!- PTM: Two-component system major event consists of a His-to-Asp
CC       phosphorelay between a sensor histidine kinase (HK) and a response
CC       regulator (RR). In plants, the His-to-Asp phosphorelay involves an
CC       additional intermediate named Histidine-containing phosphotransfer
CC       protein (HPt). This multistep phosphorelay consists of a His-Asp-His-
CC       Asp sequential transfer of a phosphate group between first an His and
CC       an Asp of the HK protein, followed by the transfer to a conserved His
CC       of the HPt protein and finally the transfer to an Asp in the receiver
CC       domain of the RR protein.
