DEG: Differentially expressed gene; NDEG: Non-differentially expressed gene; Fop: frequency of the optimal codon; GC1: GC content at the first codon position; GC2: GC content at the second codon position; GC3: GC content at the third codon position; GC: the average of GC at three codon positions. Mann–Whitney test was used in statistical analysis
