Functional analysis of differentially expressed genes in the gpx5 mutant compared to the parental strain CC4348 under laboratory growth conditions. (A) Functional subcategories of differentially expressed genes (DEGs) in the gpx5 mutant compared to the parental strain CC4348 under laboratory growth conditions. For clarity, only the genes with assigned functions are shown. Functional analysis of DEGs passing the criteria fold change greater than two (up) or less than 0.5 (down) with FDR < 1%, based on the MapMan functional classes; met, metabolism. (B) List of the DEGs related to photosynthesis and tetrapyrrole metabolism in the gpx5 mutant compared to the parent strain CC4348 under laboratory growth conditions. LHC, light-harvesting complex. (C) List of the DEGs related to cell structure and the cell cycle in the gpx5 mutant compared to the parental strain CC4348 under laboratory growth conditions. FAPs, flagellar-associated proteins. (D) The maximum efficiency of PSII (Fv/Fm) of CC4348, the gpx5 mutant, and L27 cells at a density of 2 × 106 cells mL−1 in exponential phase under laboratory growth conditions. The error bars in the graph represent standard deviations of three biological replicates.
