Root system-rhizosphere soil-bulk soil interactions in different Chinese fir clones based on fungi community diversity change

The diversity of the rhizosphere arbuscular mycorrhizal fungi (AMF) community is a crucial factor affecting root-soil interaction. They can absorb carbohydrates from host body and return nutrient elements soil to host. Using 15 Chinese fir ( Cunninghamia lanceolata Lamb. Hook.) clones, AMF richness, abundance structure in “Root system-Rhizosphere soil-Bulk soil” were obtained by Real-time quantitative PCR (qPCR) Illumina Miseq sequencing techniques. results showed that under same clone, total amount was order > root system bulk soil. species uniqueness There significant correlation between soil-available phosphorus its dominant genera species. Regarding abundance, clone S18 highest, followed clones Y061 P17. difference richness among different Glomus genus AMF. P17 S2 roots high, indicating good symbiosis community. However, P11 P41 low, variation composition group small. interaction caused gather but had less present with roots. Still, both high. content In conclusion, Clone has high forms AMF, which could be nutrient-efficient fir.
