Characterization of transgenic Arabidopsis lines overexpressing VvSNAT2. a Schematic representation of the binary cassette used for the stable transformation of Arabidopsis. b Phenotype of transgenic and wild type (WT) plants. c and d Identification of transgenic plants using reverse transcription PCR (c) and western blot analysis (d). e Chlorophyll content in transgenic and WT plants. f Melatonin content in transgenic and WT plants. Data represent mean ± SD. Asterisks indicate statistically significant differences determined using Student’s t-test (*, P < 0.05; **, P < 0.01)
