The collaborative mode by PmSVPs and PmDAMs reveals neofunctionalization in the switch of the flower bud development and dormancy for Prunus mume.

ABSTRACT: Prunus mume (Rosaceae, Prunoideae) serves as an excellent ornamental woody plant with a large-temperature-range cultivation scope. Its flower buds require a certain low temperature to achieve flowering circulation. Thus, it is important to delve into the processes of flower bud differentiation and dormancy, which affected its continuous flowering. These processes are generally considered as regulation by the MADS-box homologs, SHORT VEGETATIVE PHASE (SVP), and DORMANCY-ASSOCIATED MADS-BOX (DAM). However, a precise model on their interdependence and specific function, when acting as a complex in the flower development of P. mume, is needed. Therefore, this study highlighted the integral roles of PmDAMs and PmSVPs in flower organ develo
