PsGA2ox2 is a novel target of miR159 involved in endodormancy regulation in tree peony (Paeonia suffruticosa)
was downregulated in STTM159b buds, whereas increased in MIR159b-OE buds. In addition, the ectopic expression of PsGA2ox2 in Arabidopsis dramatically delayed seed germination and inhibited plant growth. These findings indicated a dual-target regulatory role for PsmiR159b in regulating GA homeostasis, and also revealed a PsmiR159b-PsGA2ox2 module that influenced EDR in tree peony through bioactive GA level regulation.
