The dormancy-associated MADS-box (DAM) gene DAM5 has crucial roles in bud endodormancy; however, the molecular regulatory mechanism of PpDAM5 in peach (Prunus persica) has not been elucidated. In this study, using yeast two-hybrid screening, we isolated a BTB-TAZ Domain Protein PpBT3, which interacts with PpDAM5 protein, in the peach cultivar 'Chun xue'. As expected, we found that abscisic acid (ABA) maintained bud endodormancy and induced expression of the PpDAM5 gene, and that over-expressing PpDAM5 in Arabidopsis thaliana repressed seed germination.
