Endoplasmic reticulum targeted GFP reveals ER organization in tobacco NT-1 cells during cell division
The endoplasmic reticulum (ER) of plant cells undergoes a drastic reorganization during cell division. In tobacco NT-1 cells that stably express a GFP construct targeted to the ER, we have mapped the reorganization of ...
Sewage reflects the microbiomes of human populations
(American Society for Microbiology, 2015-02-24)
Molecular characterizations of the gut microbiome from individual human stool samples have identified community patterns that correlate with age, disease, diet, and other human characteristics, but resources for marker ...
Arp2/3 complex inhibition radically alters lamellipodial actin architecture, suspended cell shape, and the cell spreading process
(American Society for Cell Biology, 2015-01-07)
Recent studies have investigated the dendritic actin cytoskeleton of the cell edge's lamellipodial (LP) region by experimentally decreasing the activity of the actin filament nucleator and branch former, the Arp2/3 complex. ...
Farm management, not soil microbial diversity, controls nutrient loss from smallholder tropical agriculture
(Frontiers Media, 2015-03-04)
Tropical smallholder agriculture is undergoing rapid transformation in nutrient cycling pathways as international development efforts strongly promote greater use of mineral fertilizers to increase crop yields. These changes ...
Long-term forest soil warming alters microbial communities in temperate forest soils
(Frontiers Media, 2015-02-13)
Soil microbes are major drivers of soil carbon cycling, yet we lack an understanding of how climate warming will affect microbial communities. Three ongoing field studies at the Harvard Forest Long-term Ecological Research ...
Effects of preservation methods of muscle tissue from upper-trophic level reef fishes on stable isotope values (δ13C and δ15N)
Research that uses stable isotope analysis often involves a delay between sample collection in the field and laboratory processing, therefore requiring preservation to prevent or reduce tissue degradation and associated ...
Acute increase of α-synuclein inhibits synaptic vesicle recycling evoked during intense stimulation
(American Society for Cell Biology, 2014-10-01)
Parkinson's disease is associated with multiplication of the α-synuclein gene and abnormal accumulation of the protein. In animal models, α-synuclein overexpression broadly impairs synaptic vesicle trafficking. However, ...
Response of benthic metabolism and nutrient cycling to reductions in wastewater loading to Boston Harbor, USA
We describe the long-term response of benthic metabolism in depositional sediments of Boston Harbor, MA, to large reductions in organic matter and nutrient loading. Although Boston Harbor received very high loadings of ...
The gut microbiota of rural Papua New Guineans : composition, diversity patterns, and ecological processes
(Cell Press, 2015-04-16)
Although recent research revealed an impact of westernization on diversity and composition of the human gut microbiota, the exact consequences on metacommunity characteristics are insufficiently understood, and the underlying ...
