Impact of rhizobacterial species richness on shoot nutrient contents (a–c). Relationship between rhizobacterial species richness and predicted nutrient contents (actual nutrient contents multiplied by plant density) (d–f). Impact of rhizobacterial species richness on root nutrient contents (g–i). Relationship between rhizobacterial species richness and predicted root nutrient contents (actual nutrient contents multiplied by plant density) (j–l).
