Conclusions Our results demonstrated that EMO effectively inhibited ferroptosis both in vivo and in vitro, while also modulating the Nrf2/HO-1/GPX4 signaling pathway to provide protection against SAP-ALI.…”

Nano-Zinc Oxide Can Enhance the Tolerance of Apple Rootstock M9-T337 Seedlings to Saline Alkali Stress by Initiating a Variety of Physiological and Biochemical Pathways by Jietao Zhai, Xulin Xian, Zhongxing Zhang, Yanxiu Wang

“…ZnO NPs can balance the osmotic adjustment system by increasing the contents of soluble protein (SP), soluble sugar (SS), proline (Pro) and starch, and can also enhance the activities of enzymatic (SOD, POD, and CAT) and non-enzymatic antioxidant enzymes (APX, AAO, GR, and MDHAR) to enhance the scavenging ability of reactive oxygen species (H₂O₂, O₂^•−), ultimately reducing oxidative damage; ZnO NPs promoted the growth of M9-T337 seedlings under saline alkali stress by synergistically responding to auxin (IAA), gibberellin (GA₃), zeatin (ZT) and abscisic acid (ABA). …”
