Genes transcript abundance of reconstructed carbon fixation pathway in Chlorella PY-ZU1 cells cultivated with 15% CO₂ gas versus air. Black dotted box indicated CO₂ transfer process (CO₂ concentrating mechanism), and red dotted box indicated Calvin cycle. Key enzymes of Calvin cycle are shown in boxes as enzyme commission (EC) numbers. Red box indicated an up-regulation, and black box indicated no significant changes
