Quantification of the phenotypes of phenotypes of the WT and samba mutant plants. Quantification of internode (A), leaf sheath (B) and blade (C) length and blade width (D) of samba mutants in comparison to the WT. Error bars represent standard error and significant differences were determined using Student’s t test: *P < 0.05, **P < 0.01 (n ≥ 3).
