Abstract

Ammonia-oxidizing bacteria (AOB) and archaea (AOA) were quantified in the sediments and roots of dominant macrophytes in eight neutral to alkaline coastal wetlands. The AOA dominated in most samples, but the bacterial-to-archaeal amoA gene ratios increased with increasing ammonium levels and pH in the sediments. For all plant species, the ratios increased on the root surface relative to the adjacent bulk sediment. This suggests that root surfaces in these environments provide conditions favoring enrichment of AOB ; This research was funded by the Spanish Ministerio de Ciencia e Innovacion (CGL2006-02382, CGL2009-08338, and CGL2011-23907) and by the Spanish Ministerio de Ciencia e Innovacion and the Donana Biological Station (ICTS 24/2007)
