TKT and infection: Sugar or energy metabolism was one of the many metabolic pathways affected during infection, and key enzymes associated with energy metabolism appeared to be upregulated in ATT and ADJ compared to PRE including transketolase (tkt), glucose-6-phosphatase (g6pc), fructose-bisphosphate aldolase C (aldoc), NADH dehydrogenase subunit 1 (nd1), and methyltransferase-like protein 17 (mettl17) (Table 1).
