Glybenclamide inhibited the movement of flavonoids in a dose-dependent manner. Seedlings of tt4-1 were incubated on increasing concentrations of glybenclamide for 24 h, transferred to slides coated with the same concentration, and N plus DPBA was applied at the root tips. The subsequent flavonoid synthesis and movement was measured after 10 min. Presented are the average and se of at least six replicates. Statistical analysis compared the indicated data point to the control (a) or the previous data point (b) using a two-tailed Student's t test for equal or unequal variance depending on F test for variance.
