Figure 5

Expression of P450 SU1 affects hypocotyl and root growth in the dark in the presence and absence of exogenous 24-epibrassinolide. Images of dark-grown 5-day old seedlings from OCP-1 and wild type in the (A) absence and (B) presence of exogenous 1 μM 24-epiBL. Scale bar is 1 mm. (C) Hypocotyl length and (D) root length in the absence (black bars) and presence (white bars) of 1 μM 24-epiBL. (E) Hypocotyl length and (F) root length in the presence of 1 μM 24-epiBL relative to sibling plants grown in the absence of exogenous hormone. OCP lines are arranged by phenotype severity, and variation is expressed as SD; n = 12 sibling plants.
