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 ...
Actin binding to WH2 domains regulates nuclear import of the multifunctional actin regulator JMY
(American Society for Cell Biology, 2012-01-19)
Junction-mediating and regulatory protein (JMY) is a regulator of both transcription and actin filament assembly. In response to DNA damage, JMY accumulates in the nucleus and promotes p53-dependent apoptosis. JMY's ...
Augmin-dependent microtubule nucleation at microtubule walls in the spindle
(Rockefeller University Press, 2013-07-01)
The formation of a functional spindle requires microtubule (MT) nucleation from within the spindle, which depends on augmin. How augmin contributes to MT formation and organization is not known because augmin-dependent MTs ...
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 ...
Gene fusions and gene duplications : relevance to genomic annotation and functional analysis
(BioMed Central, 2005-03-09)
Background: Escherichia coli a model organism provides information for annotation of other genomes. Our analysis of its genome has shown that proteins encoded by fused genes need special attention. Such composite ...
Microbial biogeography along an estuarine salinity gradient : combined influences of bacterial growth and residence time
(American Society for Microbiology, 2004-03)
Shifts in bacterioplankton community composition along the salinity gradient of the Parker River estuary and Plum Island Sound, in northeastern Massachusetts, were related to residence time and bacterial community doubling ...
Towards a Wolbachia Multilocus Sequence Typing system : discrimination of Wolbachia strains present in Drosophila species
Among the diverse maternally inherited symbionts in arthropods, Wolbachia are the most common and infect over 20% of all species. In a departure from traditional genotyping or phylogenetic methods relying on single Wolbachia ...
Future effects of ozone on carbon sequestration and climate change policy using a global biogeochemical model
Exposure of plants to ozone inhibits photosynthesis and therefore reduces vegetation production and carbon sequestration. The reduced carbon storage would then require further reductions in fossil fuel emissions to meet ...
Kinetochore alignment within the metaphase plate is regulated by centromere stiffness and microtubule depolymerases
(Rockefeller University Press, 2010-03-08)
During mitosis in most eukaryotic cells, chromosomes align and form a metaphase plate halfway between the spindle poles, about which they exhibit oscillatory movement. These movements are accompanied by changes in the ...
