The effects of plant species and plant group (grass, forb or legume)on the abundances of fungal, archaeal and bacterial phyla and the relationship between the abundance of these phyla and the effect of conditioning plant on the relative growth of chrysanthemum under conditions without versus with the pathogen.

	Plant species (df 36,105)		Plant group (df 3,138)		Relative plant growth (without Pythium/with Pythium; df 1,134)		Relative plant growth × plant group (df 5,130)		Plant biomass with Pythium (df 3,132)		Plant biomass with Pythium × plant group (df 5,130)		Plant biomass without Pythium (df 1,134)		Plant biomass without Pythium × plant group (df 5,130)
