TEMPRANILLO genes link photoperiod and gibberellin pathways to control flowering in Arabidopsis

In Arabidopsis the photoperiod pathway promotes flowering in response to longer days, but during short days flowering depends on gibberellin accumulation. This study shows that TEMPRANILLO downregulation is required to induce flowering, as TEMPRANILLO genes repress floral induction in the photoperiod and gibberellin pathways.
