Analyses are based on Bray–Curtis distances of the 14 isolates, constrained by host genotype (Geno) and experiment (Exp) to estimate their effects on the explained variance. n = 170 for PathoCom, n = 151 for CommenCom, and n = 182 for MixedCom. Statistically significant relationships (P <0.05) are in bold. Df, degrees of freedom; Sum Sq, sum of squares; F, F statistic; NA, not available.
