Última Daucus carota as a novel model to evaluate the effect of light on carotenogenic gene expression Biol. Res. STANGE,CLAUDIA; FUENTES,PAULINA; HANDFORD,MICHAEL; PIZARRO,LORENA. Carotenoids are synthesized in prokaryotic and eukaryotic organisms. In plants and algae, these lipophilic molecules possess antioxidant properties acting as reactive oxygen species scavengers and exert functional roles in hormone synthesis, photosynthesis, photomorphogenesis and in photoprotection. During the past decade almost all carotenogenic genes have been identified as a result of molecular, genetic and biochemical approaches utilizing Arabidopsis thaliana as the model system. Studies carried out in leaves and fruits of A. thaliana and tomato determined that light regulates carotenoid biosynthesis preferentially through the modulation of carotenogenic gene transcription. In this work we showed for the first time that light induces accumulation of... Tipo: Journal article Palavras-chave: Carotenoid biosynthesis; Carrot; Gene expression; Light regulation.
