However, our previous published work on this subject remains incomplete. Here, we performed a soil nutrient (nitrogen and phosphorus) transformation with related functional genes and elucidated how rhizosphere microbiota vary their response to P. liquidambari interaction throughout the plant’s life cycle under field conditions by Illumina Miseq sequencing platforms in a nutrient-limited paddy soil. Our results showed that P. liquidambari symbiosis decreased the nitrogen and phosphorus loss by 24.59% and 17.46% per pot, respectively. Additionally, we suggest that the application of P. liquidambari altered the activation of soil nitrogen and phosphorus functional genes to accelerate nutrient turnover in the rice rhizosphere. High-throughput sequencing with co-occurrence network and species-related network analysis further revealed that P. liquidambari colonization influenced the patterns of microbiota shift in the rhizosphere, especially during the heading stages. This led to an optimized microbial community through the promotion and inhibition of indigenous soil microbes with a higher level of available nutrient supplies. Our study stro...
