Effects of melatonin and 5́-Aza on disease resistance, flavonoid accumulation, transcripts and DNA methylation of the genes involved in ‘Merlot’ and/or ‘Shine Muscat’ berries. a Mycelial growth on B. cinerea-inoculated ‘Merlot’ berries treated with or without melatonin and 5́-Aza. b Phenotypes of the control and treated ‘Shine Muscat’ berries with melatonin and 5́-Aza. Decayed berries were removed at 21 DAT. c The average decay rate of ‘Shine Muscat’ berries determined at 21 DAT. d Flavonoid content in ‘Merlot’ and detached ‘Shine Muscat’ berries at 3 DAT. ND, not detected. e, f Expression difference in ‘Merlot’ (e) and detached ‘Shine Muscat’ berries (f) at 3 DAT. FC (fold change) was calculated using the ratio of the expression in the treated berries to that in the control. PAL1, VIT_216s0039g01320; STS1, VIT_216s0100g01100; EDS1, VIT_217s0000g07370; CML41, VIT_218s0001g11830. Functional annotations of the above genes were listed in Table 1. g DNA methylation in ‘Shine Muscat’ berries at 3 DAT
