Increased simulated precipitation frequency promotes greenhouse gas fluxes from the soils of seasonal fallow croplands

Journal of Sustainable Agriculture and Environment, 2023
Introduction Farmlands are key sources of greenhouse gas (GHG) emissions, which are susceptible to changes in precipitation regimes. The soils of seasonal fallow contribute approximately half of annual GHG emissions from farmlands, but the effect of ...

Update on Viral Gene Therapy Clinical Trials for Retinal Diseases [PDF]

, 2022
In 2001, the first large animal was successfully treated with a gene therapy that restored its vision. Lancelot, the Briard dog that was treated, suffered from a human childhood blindness called Leber's congenital amaurosis type 2.

Season and No-Till Rice Crop Intensification Affect Soil Microbial Populations Involved in CH4 and N2O Emissions

Frontiers in Soil Science, 2022
Rice is an important source of methane (CH4) and other crops may be sources of nitrous oxide (N2O), both of which are powerful greenhouse gases. In Uruguay, irrigated rice rotates with perennial pastures and allows high productivity and low environmental

Effects of nitrogen load on the function and diversity of methanotrophs in the littoral wetland of a boreal lake

Frontiers in Microbiology, 2012
Methane is the second most abundant greenhouse gas in the atmosphere. A major part of the total methane emissions from lake ecosystems are emitted from littoral wetlands. Methane emissions are significantly reduced by methanotrophs as they use methane as

Association of the AFF3 gene and IL2/IL21 gene region with juvenile idiopathic arthritis [PDF]

, 2010
Recent genetic studies have led to identification of numerous loci that are associated with susceptibility to autoimmune diseases. The strategy of using information from these studies has facilitated the identification of novel juvenile idiopathic ...

Activity and abundance of methane-oxidizing bacteria in secondary forest and manioc plantations of Amazonian Dark Earth and their adjacent soils

Frontiers in Microbiology, 2014
The oxidation of atmospheric CH4 in upland soils is mostly mediated by uncultivated groups of microorganisms that have been identified solely by molecular markers, such as the sequence of the pmoA gene encoding the β-subunit of the particulate methane ...

Novel methanotroph diversity evidenced by molecular characterization of particulate methane monooxygenase A (pmoA) genes in a biogas reactor

Microbiological Research, 2009
The present study for the first time investigated the diversity of methanotrophs in a biogas reactor running on cattle dung by sequence analysis of the "functional" gene, particulate methane monooxygenase A (pmoA). Community structure was determined by operational taxonomic unit (OTU) phylogenetic analyses of 396 clones belonging to pmoA library.

Aerobic Methanotrophs in Natural and Agricultural Soils of European Russia

Diversity, 2013
Human activities such as land management and global warming have great impact on the environment. Among changes associated with the global warming, rising methane emission is a serious concern.

Activity and composition of methanotrophic bacterial communities in planted rice soil studied by flux measurements, analyses of pmoA gene and stable isotope probing of phospholipid fatty acids [PDF]

Environmental Microbiology, 2007
Summary Methanotrophs in the rhizosphere of rice field ecosystems attenuate the emissions of CH 4 into the atmosphere and thus play an important role for the global cycle of this greenhouse gas.

Differentiated Mechanisms of Biochar Mitigating Straw-Induced Greenhouse Gas Emissions in Two Contrasting Paddy Soils

Frontiers in Microbiology, 2018
Straw returns to the soil is an effective way to improve soil organic carbon and reduce air pollution by straw burning, but this may increase CH4 and N2O emissions risks in paddy soils.
