highly significant−log10 ( p -value) ≥ 10
A category of Molecular Function (Chlorophyll binding; GO:0016168), three categories of Cellular Component (Chloroplast thylakoid membrane; GO:0009535, Photosys-tem II; GO:0009523, and Photosystem I; GO:0009522), and two categories of Biological Process (Protein chromophore linkage; GO:0018298, and Photosynthesis, light harvesting; GO:0009765) had a highly significant association (−log10 ( p -value) ≥ 10) in the down-regulated DEGs ( Fig. 3B ).
