BR growth responses are modified by EXO. Wild-type, exo, and transgenic exo seedlings carrying the 35S::EXOga construct were grown on half-concentrated MS medium for 7 days in the presence of different concentrations of brassinolide (BL). The experiment was carried out independently three times, representative examples of observed responses are shown. 50 plants per treatment and genotype were analyzed. Data are mean ± SD. Cotyledon, hypocotyl, and root growth in response to BL is significantly different in wild-type and exo plants (statistics in Additional file 1). A. Cotyledon length and width (mean ± SD; 100% length: 3.3 mm, 100% width 2.8 mm). B. Hypocotyl length (mean ± SD; 100%: 2.7 mm). C. Root length (mean ± SD; 100%: 30.2 mm).
