- Salt‐induced nutritional and metabolic shifts in halophytes: implications for food securityPublication . Atzori, Giulia; Caparros, Pedro Garcia; Castagna, Antonella; Custódio, Luísa; Lazazzara, Valentina; Madsen, Claus Krogh; Menicucci, Felicia; Rodrigues, Maria João; Solymosi, Katalin; Acosta Motos, Jose RamonPlant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes - whether wild or cultivated - are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce secondary metabolites posing nutritional challenges for human consumption. Moreover, halophytes often accumulate high concentrations of sodium and chlorides. However, a clear understanding of how salinity modulates the production of both the beneficial and non-nutritional factors is limited because widely variable in relation to specific environments and species. This review, written in the framework of the COST Action SUSTAIN (CA22144) on the sustainable use of salt-affected land, explores the main potential and challenges associated with the introduction of halophytes in the human diet through a revision of the effects of salinity on salt tolerant plants' secondary metabolism and mineral elements' accumulation. Moreover, the potential antioxidant, anti-inflammatory and anticancer properties of halophytes are discussed. (c) 2025 The Author(s).

- The sustainable use of halophytes in salt-affected land: state-of-the-art and next steps in a saltier worldPublication . Bazihizina, Nadia; Papenbrock, Jutta; Aronsson, Henrik; Hamed, Karim Ben; Elmaz, Özkan; Dafku, Zenepe; Custódio, Luísa; Rodrigues, Maria João; Atzori, Giulia; Negacz, KatarzynaSalinization is a major cause of soil degradation that affects several million hectares of agricultural land, threatening food security and the sustainability of agricultural systems worldwide. Nevertheless, despite the negative impact of salinity, salt-affected land also provides several important ecosystem services, from providing habitats and nurseries for numerous species to sustainable food production. This opinion paper, written in the framework of the EU COST Action CA22144 SUSTAIN on the sustainable use of salt-affected land, therefore, focuses on the potential of halophytes and saline agriculture to transform and restore key functions of these salt-affected and marginal lands. As the current knowledge on sustainable saline agriculture upscaling is fragmented, we highlight (i) the research gaps in halophyte and salinity research and (ii) the main barriers and potentials of saline agriculture for addressing food security and environmental sustainability in terms of population growth and climate change.
