Acclimation to low Cu involves changes to the photosynthetic apparatus and specific biochemical reactions that use Cu, but little is known how Cu affects cellular metabolic networks. Here we report results of whole transcriptome analysis of a plastocyanin\u2010containing diatom,\n                    <jats:italic>Thalassiosira oceanica<\/jats:italic>\n                    1005, during its initial stages of acclimation and after long\u2010term adaptation in Cu\u2010deficient seawater. Gene expression profiles, used to identify Cu\u2010regulated metabolic pathways, show downregulation of anabolic and energy\u2010yielding reactions in Cu\u2010limited cells. These include the light reactions of photosynthesis, carbon fixation, nitrogen assimilation and glycolysis. Reduction of these pathways is consistent with reduced growth requirements for C and N caused by slower rates of photosynthetic electron transport. Upregulation of oxidative stress defence systems persists in adapted cells, suggesting cellular damage by increased reactive oxygen species (ROS) occurs even after acclimation. Copper deficiency also alters fatty acid metabolism, possibly in response to an increase in lipid peroxidation and membrane damage driven by ROS. During the initial stages of Cu\u2010limitation the majority of differentially regulated genes are associated with photosynthetic metabolism, highlighting the chloroplast as the primary target of low Cu availability. The results provide insights into the mechanisms of acclimation and adaptation of\n                    <jats:italic>T<\/jats:italic>\n                    .\n
