Extended Data Fig. 2: Suppression of the GLV6OE phenotype and LR defects in mpk6 mutants.

a, Suppression of the GLV6OE phenotype in mpk6 mutants after LR initiation was induced by gravistimulation of the primary root. This experiment was done three times with similar results. b, Quantification of all primordium stages in reported mpk6 mutants compared to wild type (8 dag). Chart represents mean values ± s.d. A GEE model was used. n.s.: no significant differences were found between mutants and wild type. For full statistical analysis see Supplementary Table 2. Scale bars represent 20 μm.
