Fig. 3

Transcriptional response of photosynthesis and CO₂ fixation of C. zofingiensis to ND. a Chlorophyll biosynthesis and degradation. b Components of the light reaction and electron transport. Green and purple arrows indicate the electron transport. c Pathways of Calvin–Benson cycle and C4 like carbon fixation. Blue, black and red arrows designate down-, non- and up-regulated enzymatic steps. Heat maps show log₂(fold change) values of transcripts relative to 0 h of ND. Significant difference (absolute log₂(fold change) value > 1 and FDR adjusted p < 0.05; n = 3) is indicated with an asterisk. Time refers to the duration of ND.
