英文摘要The biological nitrogen fixation in planted and nonplanted paddy soils was quantified using a chamber-based(15)N(2)-labeling technique, and the active diazotrophs of soil were assessed by(15)N(2)-DNA-stable isotope probing (SIP). In addition, the nanometer scale secondary ion mass spectrometry (NanoSIMS) was applied to analysis the(15)N-enrichment of soil DNA in SIP fractions.N-15(2)-labeling experiment showed that BNF was 11.33 +/- 1.90 kg N ha(-1)in the rice-planted soil and 3.55 +/- 1.18 kg N ha(-1)in the nonplanted soil after 28-day labeling. The biologically fixed(15)N was mainly (> 95%) recovered in the surface layer (0-0.5 cm) in the rice-planted soil. High throughput sequencing ofnifHgenes extracted from surface soil showed that the presence of rice affected the community composition of diazotrophs. The relative abundance ofNostocalesandStigonemataleswas significantly higher in rice-planted soil than in nonplanted soil (P< 0.05). After CsCl gradient ultracentrifugation, NanoSIMS images clearly showed that(15)N was incorporated into soil DNA in the(15)N(2)-labeling SIP gradient fractions. Analyses ofnifHgenes in(15)N-enriched SIP gradient fractions suggested thatNostocalesandStigonemataleswere the major contributors to BNF in the rice-soil system. Taken together, these results have highlighted the contributions of cyanobacteria to the BNF in paddy fields and improved our understanding of the close relationship between rice plants and cyanobacteria.
