Project description:Salt marshes provide many key ecosystem services that have tremendous ecological and economic value. One critical service is the removal of fixed nitrogen from coastal waters, which limits the negative effects of eutrophication resulting from increased nutrient supply. Nutrient enrichment of salt marsh sediments results in higher rates of nitrogen cycling and, commonly, a concurrent increase in the flux of nitrous oxide, an important greenhouse gas. Little is known, however, regarding controls on the microbial communities that contribute to nitrous oxide fluxes in marsh sediments. To address this disconnect, we generated microbial community profiles as well as directly assayed nitrogen cycling genes that encode the enzymes responsible for overall nitrous oxide flux from salt marsh sediments. We hypothesized that communities of microbes responsible for nitrogen transformations will be structured by nitrogen availability. Taxa that respond positively to high nitrogen inputs may be responsible for the elevated rates of nitrogen cycling processes measured in fertilized sediments. Our data show that, with the exception of ammonia-oxidizing archaea, the community composition of organisms responsible for production and consumption of nitrous oxide was altered under nutrient enrichment. These results suggest that elevated rates of nitrous oxide production and consumption are the result of changes in community structure, not simply changes in microbial activity.

Project description:Background: Metabolic dysregulation has been implicated in bronchopulmonary dysplasia development. Taurine is an essential amino acid for neonates and is critically involved in glucose and fatty acid metabolism. Neonatal tissue obtains taurine mainly through the taurine transporter. The biological role of taurine in neonatal lung development has never been explored. As glucose metabolism mechanistically modulates angiogenesis and angiogenesis is the central player for neonatal lung development, we hypothesize that taurine depletion contributes to bronchopulmonary dysplasia development. Results: Although most genes and proteins for oxidative phosphorylation were enriched in hyperoxia pup lungs, the complex-1 activity decreased. The decrease in taurine-dependent complex-1 core subunits, ND5 and ND6, in hyperoxia lungs reasonably explained the discrepancy. Metabolomics analysis demonstrated decreased lung taurine with increased blood taurine of hyperoxia pups, compatible with the decreased taurine transporter expression. Decreased glycosylation and increased degradation explained the decreased taurine transporter expression. The results of the complementary study using tunicamycin and tauroursodeoxycholic acid studies supported that endoplasmic reticulum stress contributes to decreased taurine transporter expression in hyperoxia lungs. The effect of taurine treatment on reducing endoplasmic reticulum stress, increasing ND5 and ND6 expression, angiogenesis, and, most importantly, the alveolar formation is beneficial to hyperoxia rat pups. Conclusion: Hyperoxia exposure causes endoplasmic reticulum stress, increases taurine transporter degradation, and leads to taurine depletion in the neonatal lungs with subsequent metabolic dysregulation, resulting in poor alveolar formation of the neonatal lungs. We provide evidence of the never-being-reported protective role of taurine in neonatal lung development. The fact that taurine attenuates the severity of bronchopulmonary dysplasia by reducing hyperoxia-induced endoplasmic reticulum stress and mitochondrial dysfunction indicates its therapeutic potential for treating bronchopulmonary dysplasia.

Project description:Roothans et al., analyzed heterotrophic denitrification processes that can be an important source of nitrous oxide. We employed planktonic nitrification-inhibited denitrifying enrichment cultures under alternating oxic-anoxic conditions. The dynamic conditions resulted in a general presence of the denitrifying enzymes. Overall, we show that aerobic denitrification should not be neglected as an ecologically relevant process.

Project description:This data was generated to identify the molecular pathways responsible for nitrous oxide synthesis by the green algae Chlamydomonas reinhardtii, when supplied with nitrite under aerobic conditions (oxia). RNA samples were collected at three time points, 15 min, 3 hours, and 24 hours after the start of the experiment. The control and treatment groups were grown under the same conditions, except treatment group was supplied with 10mM nitrite at time 0. Illumina TruSeq stranded RNA libraries were synthesised from the resulting RNA before sequencing on a HiSeq2500 (125bp). The resulting sequence run generated 241,151,809 paired-end 125bp reads, of which 200,946,839 remained following quality filtering. The short data was mapped to the published genome and read counts were generated with HT-Seq count with the default settings. The raw read count data was analysed by DESeq2 in order to identify genes differentially expressed during nitrous oxide production.
