Drought stress tolerance of MtPHD6 transgenic lines. a: Phenotypic changes after drought treatment. 12-day-old seedlings were withheld water for 23 days. Photos were taken at 2 d after rehydration; b: Survival rate of MtPHD6 transgenic lines and WT after 2 d rehydration; c: Leaf water loss of MtPHD6 transgenic lines and WT. 21-day-old leaves were detached and air-dried for up to 8 h. d: Leaf water content of MtPHD6 transgenic lines and WT after 7, 14, 21 d drought treatment
