Stronger effects of genotype than treatment on the floral microbiome. a, Bacterial Shannon diversity (least-squares means) differed among strawberry genotypes contingent upon treatments, after controlling for all other factors in a general linear mixed model (LMM, detailed statistics in Supplementary Table 1). Significant least-squares mean contrasts are denoted: ^*P < 0.05; ^**P < 0.01. Error bars represent 1 SE. b, The least-squares means of fungal Shannon diversity (power-transformed, power parameter = 2) were similar among genotypes and treatments (LMM, detailed statistics in Supplementary Table 1). The least-squares mean contrasts showed that fungal Shannon diversity only differed in Wasatch between mycorrhizae and herbivory + mycorrhizae treatments. c and d, The constrained principal coordinates analyses (cPCoAs) revealed significant effects of genotype but not treatment on the bacterial and fungal community compositions (detailed statistics in Supplementary Table 1).
