Enhancer and promoter activities associated with light/dark cycles. a Oscillation of the 35S promoter activity under 12 h light/12 h dark condition. b Oscillation of activities of seven enhancers under 12 h light/12 h dark condition. For data comparison between (a) and (b), the first peak value of the 35S promoter of (a) at 30 h was set as 1. c Luminescence activity of the 35S promoter under dark condition. d Luminescence activity of seven enhancers under dark condition. For data comparison between (c) and (d), the first peak value of the 35S promoter from (c) at 40 h was set as 1. Each data point was collected every 4 h after agroinfiltration. Data represent the mean ± SEM (n = 3)
