qRT–PCR analysis of 12 PbrABC transporter genes under salt and drought stress. A. Expression pattern of 12 PbrABC transporter genes under salt treatment for 0 h, 4 h, 6 h, 12 h, 24 h and 48 h, respectively. B. Expression pattern of 12 PbrABC transporter genes under drought treatment (10% PEG6000) for 0 h, 1 h, 3 h, 6 h and rehydration for 24 h, respectively. All experiments were performed independently at least three times
