BT2 is a BTB/TAZ domain protein with key roles in multiple stress responses and the plant development of Arabidopsis (Figueroa et al. 2005; Ren et al. 2007; Mandadi et al. 2009). Recent studies have demonstrated that apple MdBT2 functions as a negative regulator in diverse hormonal and environmental signal‐induced anthocyanin biosynthesis, suggesting that MdBT2 integrates stress signals and anthocyanin biosynthesis.
