What's a GeneRIF?

There are four CONSTANS transcriptional activators FBH1-4 which are related basic helix-loop-helix-type transcription factors that preferentially bind to the E-box cis-elements in the CO promoter. Overexpression of all FBH genes drastically elevated CO levels and caused early flowering regardless of photoperiod. [FBH2]
Title: FLOWERING BHLH transcriptional activators control expression of the photoperiodic flowering regulator CONSTANS in Arabidopsis.
