Plastid-mediated feedback regulation of Arabidopsis LYCOPENE EPSILON CYCLASE is modulated by the promoter and a 5′UTR structural variant harbouring a conserved IRES

Abstract Background Perturbations in flux through the carotenoid pathway can signal control over nuclear gene expression to maintain metabolic homeostasis in plastids; however, the genetic targets and mechanisms are rarely characterised in plants. Results Utilising mutants, over- and exogenous expre...
