Fig. 4: Ipt3 and Ipt4 contribute to maintenance of nodule initiation in the presence of nitrate.

A Nodule primordia number in the absence and presence of 5 mM KNO3 at 7dpi with M. loti. B Infection thread density in the absence and presence of 5 mM KNO3 at 7dpi with M. loti. Bars show mean ± SE with significant differences between genotypes and nutrient conditions indicated by letters (p < 0.05) as determined by ANOVA and Tukey post-hoc analysis. Pairwise P-values are available in the Source Data file. The n values of each group are shown.
