Abundance of Novel and Diverse tfdA-Like Genes, Encoding Putative Phenoxyalkanoic Acid Herbicide-Degrading Dioxygenases, in Soil

Zaprasis, Adrienne; Liu, Ya-Jun; Liu, Shuang-Jiang; Drake, Harold L.; Horn, Marcus A. (Washington, DC [u.a.] : American Soc. for Microbiology, 2010)

Phenoxyalkanoic acid (PAA) herbicides are widely used in agriculture. Biotic degradation of such herbicides occurs in soils and is initiated by α-ketoglutarate- and Fe2+-dependent dioxygenases encoded by tfdA-like genes ...
Competing Formate- and Carbon Dioxide-Utilizing Prokaryotes in an Anoxic Methane-Emitting Fen Soil

Hunger, Sindy; Schmidt, Oliver; Hilgarth, Maik; Horn, Marcus A.; Kolb, Steffen; Conrad, Ralf; Drake, Harold L. (Washington, DC [u.a.] : American Soc. for Microbiology, 2011)

Methanogenesis in wetlands is dependent on intermediary substrates derived from the degradation of biopolymers. Formate is one such substrate and is stimulatory to methanogenesis and acetogenesis in anoxic microcosms of ...
Effect of Earthworm Feeding Guilds on Ingested Dissimilatory Nitrate Reducers and Denitrifiers in the Alimentary Canal of the Earthworm

Depkat-Jakob, Peter S.; Hilgarth, Maik; Horn, Marcus A.; Drake, Harold L. (Washington, DC [u.a.] : American Soc. for Microbiology, 2010)

The earthworm gut is an anoxic nitrous oxide (N2O)-emitting microzone in aerated soils. In situ conditions of the gut might stimulate ingested nitrate-reducing soil bacteria linked to this emission. The objective of this ...
Evolution of the Rdr1 TNL-cluster in roses and other Rosaceous species

Terefe-Ayana, Diro; Kaufmann, Helgard; Linde, Marcus; Debener, Thomas (London : BioMed Central Ltd., 2012)

Background: The resistance of plants to pathogens relies on two lines of defense: a basal defense response and a pathogen-specific system, in which resistance (R) genes induce defense reactions after detection of ...
Genome-Derived Criteria for Assigning Environmental narG and nosZ Sequences to Operational Taxonomic Units of Nitrate Reducers

Palmer, Katharina; Drake, Harold L.; Horn, Marcus A. (Washington, DC [u.a.] : American Soc. for Microbiology, 2009)

Ninety percent of cultured bacterial nitrate reducers with a 16S rRNA gene similarity of ≥97% had a narG or nosZ similarity of ≥67% or ≥80%, respectively, suggesting that 67% and 80% could be used as standardized, conservative ...
Novel [NiFe]- and [FeFe]-Hydrogenase Gene Transcripts Indicative of Active Facultative Aerobes and Obligate Anaerobes in Earthworm Gut Contents

Schmidt, Oliver; Wüst, Pia K.; Hellmuth, Susanne; Borst, Katharina; Horn, Marcus A.; Drake, Harold L. (Washington, DC [u.a.] : American Soc. for Microbiology, 2011)

The concomitant occurrence of molecular hydrogen (H 2) and organic acids along the alimentary canal of the earthworm is indicative of ongoing fermentation during gut passage. Fermentative H 2 production is catalyzed by ...
Transcriptional responses to polycyclic aromatic hydrocarbon-induced stress in Arabidopsis thaliana reveal the involvement of hormone and defense signaling pathways

Weisman, David; Alkio, Merianne; Colón-Carmona, Adan (London : BioMed Central Ltd., 2010)

Background: Polycyclic aromatic hydrocarbons (PAHs) are toxic, widely-distributed, environmentally persistent, and carcinogenic byproducts of carbon-based fuel combustion. Previously, plant studies have shown that PAHs ...
