Effect of the activation of rice Gα in the BR response. The seeds of Nipponbare, DK22 (an allele of d1), QL/DK22 and d11-4 (a mutant of the BR-biosynthetic enzyme, CYP724B1) were sown onto agar medium supplemented with or without the indicated concentration of 24-epiBL. Each set of columns from dark gray to white represent the values from plants grown at 0, 10−8, 10−7, 2 × 10−7, 5 × 10−7 and 10−6 M of 24-epiBL respectively. The upper and lower panels are the scores expressed in actual values and relative values. The relative values are expressed in terms of the increase in length relative to treatment with 24-epiBL-free medium (defined as 100%). Each value is the mean of 12 seedlings. Experiments were repeated at least 3 times. Asterisks denote statistically significant p-value for the differences measured by a two-tailed t-test, with regard to greater scores than those in WT. (Error bars = SE).
