Altering N₂O emissions by manipulating wheat root bacterial community.

ABSTRACT: Nitrous oxide (N₂O) is a greenhouse gas and a potent ozone-depleting substance in the stratosphere. Agricultural soils are one of the main global sources of N₂O emissions, particularly from cereal fields due to their high areal coverage. The aim of this study was to isolate N₂O-reducing bacteria able to mitigate N₂O emissions from the soil after inoculation. We isolated several bacteria from wheat roots that were capable of N₂O reduction in vitro and studied their genetic potential and activity under different environmental conditions. Three of these isolates- all carrying the nitrous oxide reductase-encoding clade I nosZ, able to reduce N₂O in vitro, and efficient colonizers of wheat roots- presented different N₂
