Amino acid pathway analysis. (A) Schematic diagram of the amino acid pathway. Multiple enzymatic reactions are illustrated by stacked arrows. Abbreviations: BCAT: branched-chain amino acid transaminase; PDC: pyruvate decarboxylase; ADH: alcohol dehydrogenases; AAT: alcohol acyl-transferases; PAL: phenylalanine ammonia lyase; EGS: eugenol synthase; (B) Expression level of biosynthetic genes related to the amino acid pathway in the fruit of ‘Benihoppe’ (WT) and ‘Xiaobai’ (mut) at four developmental stages. Darker red indicates a higher expression level, whereas darker blue indicates a lower expression level.
