Drought and salt tolerance analysis of PeGSTU58 transgenic seedlings in panel growth condition. (A) The image of 35S::PeGSTU58 (OE-11 and OE-17) and WT seedlings under normal condition, salt treatment, and drought treatment in plate. (B) qRT-PCR analysis of PeGSTU58 expression level in 35S::PeGSTU58 (OE-11 and OE-17) and WT seedlings. (C,D) The fresh weight and root lengths of both WT and PeGSTU58-overexpressing seedlings were measured under normal conditions, salt, and drought stress treatments. Measurements of fresh weight and primary root lengths of 35S::PeGSTU58 (OE-11 and OE-17) and WT under normal, salt, and drought stress conditions. Significance test was conducted using Student’s t-test (* p < 0.05 and ** p < 0.01).
