24-epibrassinolide (EBR) regulates root development. (A) The development of lateral roots was enhanced in EBR-treated seedlings. Each plate contained 10 nM EBR or mock solution (control). The red line represents initial length before treatment; (B) Differences in primary root length between day 5 and day 11. Primary root length was significantly shorter under EBR treatment; and (C) Number of lateral roots on day 11. Lateral root number was significantly increased in the EBR supplement plate. Representative data from three independent experiments are presented as mean ± SD. *p < 0.05, **p < 0.01 vs. control treatment values.
