Fig. 7From: Long-term effects of mixed planting on arbuscular mycorrhizal fungal communities in the roots and soils of Juglans mandshurica plantationsOrdination plots of the results from the redundancy analysis (RDA) to identify the relationships among the AM fungal taxa (Black arrows) and the soil characteristics (Red arrows). The top 20 most abundant classified AM fungal OTUs (97% sequence similarity) in the root (A) and soil (B) samples. Cmic: soil microbial biomass carbon. Nmic: soil microbial biomass nitrogen. TPh: soil total phenol. CPh: soil complex phenol. WSPh: soil water-soluble phenol. NO3: NO3−-N. NH4: NH4+-NBack to article page
