The expression levels of CpMAPKs in papaya flesh in response to the combined treatment of AsA and chitosan. The papaya fruit tissues were sampled at 0, 8 and 16 d after being subjected to AsA and CTS treatment. Untreated fruits were used as a control. The relative expression levels were determined by qRT-PCR, and calculated by ΔΔCt method. The asterisks indicate significant differences between CK and AsA + CTS combined treatments by Student’s t-test: * P < 0.05; ** P < 0.01, respectively
