The Adonis test was based on Bray-Curtis distance matrices for nematode community dissimilarity assessments using 1000 permutations.
Significance of test indicated as ***p < 0.001 and *p < 0.05, and R2 is the proportion of variation explained.
Each mutant was tested against the respective parental line.
Ler-0 is the parental line of tt3-1 and tt3-1tt5-1; Col-0 is the parental line of all other mutants.
