What is it about?
Flowering is regulated by the interplay between distinct endogenous pathways, but the outputs are not universal. We show here a cooperative network regulating flowering in the day-neutral tomato. This network integrates the phytohormone gibberellin and two unrelated miRNA-regulated pathways with opposing roles in flowering time in a day-neutral species.

Why is it important?
Our findings show that the regulation of SFT and floral identity genes by the recruitment of age cues via miR156-targeted SlSBPs and their interactions with GA and the miR319-LA module is the core feature of the mechanisms underlying meristem maturation and floral transition in cultivated tomato.
Perspectives
We hope that our findings will help to better understand the modulation of flowering time and inflorescence development in the day-neutral tomato, which might impact tomato breeding.
