Climate and species affect fine root production with long-term fertilization in acidic tussock tundra near Toolik Lake, Alaska
Long-term fertilization of acidic tussock tundra has led to changes in plant species composition, increases in aboveground production and biomass and substantial losses of soil organic carbon (SOC). Root litter is an ...
Characterisation of the subtelomeric regions of Giardia lamblia genome isolate WBC6
Giardia trophozoites are polyploid and have five chromosomes. The chromosome homologues demonstrate considerable size heterogeneity due to variation in the subtelomeric regions. We used clones from the genome project with ...
Comparative sequence analysis of IS50/Tn5 transposase
(American Society for Microbiology, 2004-12)
Comparative sequence analysis of IS50 transposase-related protein sequences in conjunction with known structural, biochemical, and genetic data was used to determine domains and residues that play key roles in IS50 ...
Exploring the relationship between sequence similarity and accurate phylogenetic trees
(Oxford University Press, 2006-08-04)
We have characterized the relationship between accurate phylogenetic reconstruction and sequence similarity, testing whether high levels of sequence similarity can consistently produce accurate evolutionary trees. We ...
EGenBio : a data management system for evolutionary genomics and biodiversity
(BioMed Central, 2006-09-26)
EGenBio is a system for manipulation and filtering of large numbers of sequences, integrating curated sequence alignments and phylogenetic trees, managing evolutionary analyses, and visualizing their output. EGenBio is ...
Novel γ-carboxyglutamic acid-containing peptides from the venom of Conus textile
The cone snail is the only invertebrate system in which the vitamin K dependent carboxylase (or γ-carboxylase) and its product γ-carboxyglutamic acid (Gla)1 have been identified. It remains the sole source of ...
Odorant specificity of three oscillations and the DC signal in the turtle olfactory bulb
The odour-induced population response in the in vivo turtle (Terepene sp.) olfactory bulb consists of three oscillatory components (rostral, middle and caudal) that ride on top of a DC signal. In an initial step to determine ...

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 ...
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 ...
