Desalination has exponentially increased in the Mediterranean basin due to water scarcity. Transplantation experiments were performed with endemic seagrass P. oceanica following a brine dilution plume desalination plant Spain. placed at 3 locations: control (~37 psu), intermediate influence (IB, ~39.5 psu) and high (HB, ~42 psu). Reactive oxygen species endpoints (i.e. H2O2, lipid peroxidation, ascorbate) regulation of genes involved antioxidant osmoregulation analysed 1, 6 days. H2O2 TBARS IB HB, ASC decreased indicating ROS excess, peroxidation consumption. Genes related (SOS1, SOS3, AKT2/3) response (GR, APX, FeSOD, MnSOD, STRK1) upregulated brine-exposed plants, especially early experiment stages, later evidence drop although still within positive levels expression. The results showed that recorded oxidative stress osmoregulatory responses caused by brines interacting other environmental pressures natural and/or anthropogenic). approach delivered battery biomarkers can be also globally applied using relevant macrophytes seagrasses, macroalgae) for monitoring programs (EMPs), address stressors their isolated/combined contribution marine pollution.
