Comparison of disease functional parameters of Medicago truncatula nodulation mutants Mutants are in the Jemalong-A17 (resistant) genetic background. Plants were grown in peat substrate and inoculated by a conidial suspension of V. albo-atrum (10⁶ spores ml^–1). Disease symptom scoring was done in three independent experiments. P-values refer to test for difference between the parameter of the mutant line compared to that of the wild reference Jemalong-A17. Bold indicates significant (P < 0.05) or subsignificant (P < 0.10) differences compared to the reference line Jemalong-A17. [R] and [S] indicate resistant and susceptible lines, respectively.
