Divergent Patterns of Metabolite Expression in Red Seaweeds (Devaleraea mollis and Palmaria hecatensis) Following Nitrate and Ammonium Supplementation.

ABSTRACT: This study explores species-specific metabolic responses to different nitrogen-rich formulations in Devaleraea mollis and Palmaria hecatensis, highlighting distinct adaptive strategies. We evaluated the effects of Von Stosch Enrichment (VSE, nitrate-only), F/2 (nitrate-only), and Jack's Special (JS, nitrate and ammonium) on metabolic profiles. D. mollis exhibited elevated energy storage and growth-related metabolites, with JS enhancing creatine production for energy storage and regeneration, alongside increased DNA/RNA synthesis and cell division activity. This suggests D. mollis prioritizes rapid growth and energy demands, supporting broader ecological adaptability. Conversely, P. hecatensis showed higher expression of metabolites linked to amino acid me
