Table 1.

Selected proteins involved in oxidative stress discussed here. Protein abundance and fold change in samples grown under white light were compared to non-illuminated control. NCBI accession numbers as well as matched KO identifiers are listed. Further identified unique peptides, significance and fold change at 40 h and 122 h of samples are stated. Fractions below 1 depict downregulation. n.d. = not detected.
