Anatomical and metabolomic variability in marine plants can provide valuable insights into species adaptive strategies and resilience to environmental changes. This study explores the anatomical characteristics and metabolomic profiles of Posidonia oceanica fruits, a key Mediterranean seagrass species, collected from three areas in Sardinia (Alghero, Oristano, and Olbia). Anatomical analyses of pericarps assessed cuticle thick...

Key message ABC1K2 links stress response and seed development. Abstract The Activity of BC1 complex Kinases (ABC1K) family comprises atypical protein kinases with a conserved ABC1 domain and widespread distribution across life domains. In plants, ABC1Ks are predominantly localised in chloroplasts and mitochondria and have been implicated in energy metabolism, abiotic stress response, and developmental processes. Despite growin...
