Allelic variation of BSK3 determines root length. a Schematic of transgenic constructs used for complementation of the bsk3,4,7,8 quadruple mutant and representative photographs of 6-day-old plants. Three representative lines for each construct are shown. Scale bar, 1 cm. b Primary root length of bsk3,4,7,8 and 14 independent T2 lines for each construct. Bars represent means ± SEM (n = 20 independent biological replicates). Average values of 14 independent lines for each construct are also shown (all comb.). Asterisks indicate statistically significant differences between complementation lines and bsk3,4,7,8 mutant or between two BSK3 protein variants according to Welch’s t-test (*P < 0.01)
