dar-1 is not suppressed by CLE peptide expression. Wild type R108 and dar-1 plants with roots carrying control (EV), p35S::CLE12, or p35S::CLE13 plasmids were inoculated with Sinorhizobium medicae and assessed for nodulation after 21 days (n = 7 to 9 plants per condition). Nodulation was suppressed by CLE12 or CLE13 expression in the wild type (Kruskall-Wallis test p < 0.05) but not in dar-1 (Kruskal–Wallis test p > 0.05). Different letters denote significant differences (p < 0.05) in pairwise comparisons for each genotype using Dunn’s post-hoc test
