The outcome revealed that exogenous ABA accelerated the accumulations of complete phenolic and flavonoid contents; mainly enhanced the contents of detected phenolic compounds; improved FRAP and DPPH activity; and presented the activities of PAL, POD, PPO, CAT, and APX during tomato ripening. Meanwhile, the expressions associated with the significant genes (PAL1, C4H, 4CL2, CHS2, F3H, and FLS) active in the phenylpropanoid pathway were up-regulated (1.13- to 26.95-fold) in the tomato
