Gene expression in Skeletonema marinoi grown in CO2-enriched or CO2-enriched Si-starved medium. Expression levels of heat shock proteins, aldehyde dehydrogenases, glutathione-related enzymes and other antioxidants in S. marinoi during exponential, stationary and decline growth phases (EXP, STAT, DECL) in CO2-enriched medium (a) or in CO2-enriched/Si-starvation medium (b), using S. marinoi grown in complete medium as control (x-axis; * for p < 0.05, ** for p < 0.01 and *** for p < 0.001). Data are represented as log2 x-fold expression ratio ± SD. Gene abbreviations used are: Heat shock proteins (HSP), luminal binding protein (LBP), aldehyde dehydrogenases (ALDH), succinate dehydrogenase (SSD), betaine ALDH (BALDH), glutathione synthase (GSH-S), glutathione peroxidase (GPX), glutathione reductase (GR), glutathione S-transferase (GST), catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (AP), tocopherol cyclase (TOCC), glycolate oxidase (GOX), ATP-binding cassette transporter (ABC).
