Overexpression of PbeNAC1 confers enhanced drought resistance in transgenic lines. (A) Representative photographs of 30-days-old WT and the two transgenic lines (OE3 and OE7) drought for 15 days, followed by recovery for 7 days. (B) Phenotypes of 60-days-old WT and the two transgenic lines before and after drought stress for 15 days, After normal growth for 7 days. (C–E) EL (C) survival rate (D) and proline content (E) in the WT and transgenic lines measured after drought stress for 15 days. (F) Detection of H2O2 and O2- accumulate in leaves of transgenic and WT plants normal and unnormal condition based on histochemical staining with NBT (a,b) and DAB (c,d), respectively. Asterisks indicate that the value is significantly different from that of the WT at the same time point (∗∗∗P < 0.001).
