Oxidative stress promotes lateral root emergence in the wav2-1 mutant. Lateral roots of 11-day-old seedlings grown in hydrotropism assay medium were counted. Paraquat (PQ)-inhibited lateral root emergence was observed in all mutants tested, except the wav2-1 mutant. Bars indicate means ± standard error (SE) from three biological replicates. *Indicates significant differences compared to controls and PQ-treated medium using Dunn´s multiple comparison test, Kruskal-Wallis test, and Mann-Whitney U test, from three biological replicates (P < 0.05). n = 30.
