29-bp indel variation analysis. a 29-bp indel variation detected in 176 A. arguta accessions. b Promoter diagram of AaLDOX with a 29-bp indel in red and green A. arguta cultivars. c The activity of the AaLDOX promoter with a 29-bp insertion and deletion was analyzed via a luminescence intensity imaging system. Blue and red represent low and high luminescence intensities, respectively. d Relative luciferase activity of the AaLDOX promoter with a 29-bp insertion and deletion. The values are the means ± SDs of three replicates. Statistical significance: *P < 0.05
