A NAC family gene <i>PmNAC32</i> associated with photoperiod promotes flower induction in <i>Prunus mume</i>.

ABSTRACT: The photoperiod is essential to flower induction, and the exact timing of the process can be precisely regulated based on the relative duration of light and darkness. However, the mechanisms linking photoperiod and flower induction in woody plants remain largely unexplored. Using RNA-seq, we identified a photoperiod response factor PmNAC32, which is predominantly expressed in early-flowering varieties. Overexpression of PmNAC32 in Arabidopsis thaliana, tobacco, and Prunus mume calli resulted in accelerated flowering. Binding and activation analyses revealed that PmNAC32 can be directly suppressed by REVEILLE 1 (RVE1) and REVEILLE 3 (RVE3), implying that PmNAC32 plays a role in the photoperiodic signaling pathway. Further studies established that Pm
