For example, in tryptophan metabolism (Figure S5A in Supplementary Material), the expression of tryptophan hydroxylase 1 (TPH1, FC = 61) and tryptophan 2,3-dioxygenase (TDO2, FC = 4.2) was upregulated, potentially affecting tryptophan biosynthesis after CH60 infection. This evidence concerns the gene TPH1 and infection.
