High Methane Production and Emission From Tropical Seagrasses Through Methylotrophic Methanogenesis
Abstract Methane (CH4) is a potent greenhouse gas that reduces the carbon sequestration capacity of seagrass meadows. However, our understanding of CH4 production and emission from these important carbon sinks is limited. Here we conducted biogeochemical experiments to identify methylotrophic methanogenesis as the primary methanogenesis pathway in a ...

Dual 222Rn Models for Tracing Groundwater–Lake Water Exchange in a Flow‐Through Lake
Abstract Groundwater–lake water exchange in flow‐through lakes which includes both groundwater discharge into the lake and lake water seepage into the aquifer, is crucial for sustaining lake wetland ecosystems; however, these two processes are rarely addressed simultaneously by tracer methods.

Regulated expression of theSaccharomyces cerevisiaeDNA repair gene RAD7 in response to DNA damage and during sporulation [PDF]
The RAD7 gene of Saccharomyces cerevisiae affects the proficiency of excision repair of DNA damaged by UV light. Here, we report our studies on the regulation of the RAD7 gene in response to UV irradiation and during sporulation. RAD7 transcript levels increased 6-fold within 40 min of exposure of cells to 37 J/m2 of UV light.

Sandy Subterranean Estuaries Minimize Groundwater Nitrogen Pollution Impacts on Coastal Waters
Abstract Widespread anthropogenic activities pollute groundwater that eventually seeps out to the coastal ocean. Here, we resolve nutrient transformations and fluxes in 11 sandy subterranean estuaries (STEs) with contrasting nutrient sources and development trajectories.

During Nucleotide Excision Repair (NER) in the yeast S. cerevisiae, ubiquitylation of Rad4 is carried out by the E3 ubiquitin ligase that includes Rad7-Elc1-Cul3 and is critical to optimal NER. Rad7 E3 activity targets Rad4 for degradation by the proteaseome but, in principle, could also trigger other DNA damage responses. We observed increased nuclear

Abstract The tidal tributaries of the lower Chesapeake Bay experience seasonally recurring harmful algal blooms and the significance of submarine groundwater discharge (SGD) as a nutrient vector is largely unknown. Here, we determined seasonal SGD nutrient loads in two tributaries with contrasting hydrodynamic conditions, river‐fed (York River) vs ...

UV-induced sumoylation in wild type and NER-deficient cells.
Log phase cells were irradiated with UV and incubated in a rich medium at 30°C. Rpb1 was immunoprecipitated from the cells at different times of the post-UV incubation using antibody 8WG16 and probed with anti-SUMO and 8WG16 antibodies.

Abstract Lacustrine groundwater discharge (LGD) is an important water and nutrient source for lakes. Despite its importance, high‐resolution quantifying the spatial variability of LGD remains challenging. Particularly, little studies have explored the impact of the interaction zone structure between lakes and aquifers on this variability. Present study
