| Zusammenfassung |
| The role of plant traits in driving components of the N cycle is poorly characterised. Here we demonstrate plant-derived C to regulate nitrous oxide (N2O) production and reduction in the rhizosphere. We use isotope (13C, 14C and 15N) techniques and a new isotope-FISH-FACS approach to verify (i) the link between plant-C and activity of microbial nitrate reducers, (ii) uptake of C compounds into pseudomonads, (iii) the role of both composite rhizodeposits and individual compounds in regulating the magnitude of N2O emission, and (iv) their influence on the N2O:N2 product ratio. We examine the potential these relationships offer to use plants to manipulate the rhizosphere for reduction of N2O emissions and the possibility of characterising plant ‘rhizotraits’ that enhance reduction of N2O to N2. |
