In the published article, there was an error in Figure 6A, Figure 7C as published. In Figure 6A, the representative photo of TaOE2 was duplicated and used as TaOE3 at 0 day. In Figure 7C, the representative photo of TaOE2 was duplicated and used as TaOE3. The corrected Figure 6A and its caption “Figure 6 TaPRX-2A overexpression increased the drought tolerance. (A) Phenotype of TaPRX-2A-overexpressing transgenic and WT wheat (the cultivar “KN199”) with drought treatment. (B) Survival rates of TaPRX-2A-overexpressing transgenic lines and WT wheat. (C) shoot length of TaPRX-2A-overexpressing transgenic lines and WT wheat. (D) Relative water content (RWC), and (E) root length. (F) MDA content of TaPRX-2A-overexpressing transgenic lines and WT wheat. (G) soluble sugar content of TaPRX-2A-overexpressing transgenic lines and WT wheat. (H) proline content, and (I) soluble protein content of TaPRX-2A-overexpressing and WT plants. All experiments included three replicates and the data present the mean ± SD. *P < 0.05 and **P < 0.01 indicate a significant difference compared with WT.” and the corrected Figure 7C along with its caption “Figure 7 Analysis of ROS scavenging capacity andantioxidant enzymes activity in transgenic wheat lines. (A) Detection of O₂⁻ generation by NBT staining and O₂⁻ content (B). (C) Detection of H₂O₂ accumulation by DAB staining and H₂O₂ content (D). (E) Detection of SOD activity in TaPRX-2A-overexpressing transgenic lines and WT wheat. (F) Detection of CAT activity in TaPRX-2A-overexpressing transgenic lines and WT wheat. (G) Detection of POD activity in TaPRX-2A-overexpressing transgenic lines and WT wheat. All experiments included three replicates and the data present the mean ± SD. *P < 0.05 and **P < 0.01 indicate a significant difference compared with WT.” appear below.
