Gibberellin responses. (A) Bowman and Zeo1.b, uzu1.a and sdw1.a plants treated with mock or 0.01 mM gibberellin (GA₃). (B) Culm lengths of Bowman, sdw1.a, uzu1.a and Zeo1.b plants following treatment with mock, 0.001 mM and 0.01 mM GA₃ (n=7-10/genotype/treatment). (C) Long-cell length (µm) per 1 cm segment up the peduncle following either mock or 0.01 mM GA₃ (n=3/genotype/treatment). (D) Long cell number per file in peduncles treated with mock or 0.01 mM GA₃ (n=3 peduncles with 10 cells measured per cm/genotype). Box plots show 25th to 75th percentiles; whiskers extend down to 10th and up to 90th percentiles; black line shows median; and red line shows mean. (E) Culm lengths of Bowman, uzu1.a, Zeo1.b and uzu1.a Zeo1.b plants (n=7-19/genotype). (F) Culm lengths of Bowman, sdw1.a, Zeo1.b and sdw1.a Zeo1.b plants (n=10/genotype). Bw, Bowman. *P<0.05; ***P<0.001 (Student's t-test). nd, not statistically different. Scale bars: 5 cm. Error bars represent s.e.m.
