The reduction of fertilizer usage is one of preferable field managements to attain sustainable agriculture. Herein, we applied metagenomic analysis to rice root-associated microbiome to understand microbial community shifts in paddy rice field ecosystems under different N fertilizer regimes. Rice pl .. [more]ants were cultivated in paddy fields dressed with low N (LN; 0 kg ha-1), standard N (SN; 30 kg ha-1). Prior to the experiments, LN field has not been subjected to N fertilization for consecutive 5 years. Our analysis revealed that low input of N fertilizer drastically changed the functionalities of rice root-associated microbes relevant to N2 fixation, plant hormonal effect and methane cycling.
