3 Tracing changes in ecosystem function under elevated carbon dioxide conditionsResponses of ecosystems to elevated levels of atmospheric carbon dioxide (CO2) remain a critical uncertainty in global change research. Two key unknown factors are the fate of carbon newly incorporated by photosynthesis into various pools within the ecosystem and the extent to which elevated CO2 is...Elevated carbon dioxide; Stable isotopes; Radiocarbon; Global change; Terrestrial ecosystems2003
4 LIM proteins in actin cytoskeleton mechanoresponseThe actin cytoskeleton assembles into branched networks or bundles to generate mechanical force for critical cellular processes such as establishment of polarity, adhesion, and migration.

5 Ecological processes dominate the 13C land disequilibrium in a Rocky Mountain subalpine forestFossil fuel combustion has increased atmospheric CO2 by ≈ 115 μmol mol1 since 1750 and decreased its carbon isotope composition (δ13C) by 1.7-2‰(the 13C Suess effect). Because carbon is stored in the terrestrial biosphere for decades and longer, the δ13C of CO2 released by terrestrial ecosyst...2014-01-01
6 ATPase-Independent Type-III Protein Secretion in Salmonella entericaType-III protein secretion systems are utilized by gram-negative pathogens to secrete building blocks of the bacterial flagellum, virulence effectors from the cytoplasm into host cells, and structural subunits of the needle complex. The flagellar type-III secretion apparatus utilizes both the energy...2014-01-01
7 Origin and destiny of adenovirus proteinsLytic infection of human cells by adenovirus proceeds by a temporal expression of genes. Classically two phases have been defined: an early phase, which includes events occurring before the onset of DNA synthesis (8 hours), and a late phase, including events whose existence depends on the onset of...Protein Biosynthesis; DNA, Viral; Adenoviridae; RNA, Viral; Time Factors1975
8 Divergent defensive strategies of young leaves in two species of IngaIn the recently radiated genus Inga (Fabaceae), few nucleotide substitutions have accumulated among species, yet large divergences have occurred in defensive phenotypes, suggesting strong selection by herbivores. We compared herbivory and defenses of young leaves for I. goldmanii, a more derived spe...Bioassays; Flavanoids; Heliothis virescens; Herbivory; Inga goldmanii; Inga umbellifera; Leaf development; Non-protein amino acids; Phoebis philea2005
9 Purification and characterization of mouse hypoxanthine-guanine phosphoribosyltransferase.Hypoxanthine-guanine phosphoribosyltransferase (HGPR transferase) (EC has been purified approximately 4500-fold to apparent homogeneity from mouse liver.

10 MotA protein of E. coli is a proton-conducting component of the flagellar motorA number of mutants of motA, a gene necessary for flagellar rotation in E. coli, were isolated and characterized. Many mutations were dominant, owing to competition between functional and nonfunctional MotA for a limited number of sites on the flagellar motor. A new class of mutant was discovered...MotA protein; MotA gene; Flagellar motor; Proton-conducting1990
11 Polypetide chain termination. Purification of the release factors, R1 and R2, from Escherichia coli.We have extensively purified the release factors RI and Rz from Escherichia coli. These proteins can each mediate polypeptide chain termination. The physiological substrate for this reaction is a completed polypeptide chain in a peptidyl- transfer RNA-messenger RNA-ribosome complex. The reaction con...Acrylates; Detergents1971-02-25
12 Cysteine-rich protein family of highly related LIM domain proteinsHere we describe a family of closely related LIM domain proteins in avian cells. The LIM motif defines a zinc-binding domain that is found in a variety of transcriptional regulators, proto-oncogene products, and proteins associated with sites of cell-substratum contact. One type of LIM-domain protei...LIM domains; Chicken embryo fibroblasts; Quail embryo fibroblasts; Cell growth; Cell development; Cysteine-rich proteins1995
13 Solanaceae: the potato familyShrubs, herbs, woody vines, occasionally trees, glabrous or pubescent with simple, glandular, branched, or star-shaped hairs, sometimes with prickles. Lvs alternate or paired but not truly opposite, simple or lobed to pinnately compound; stipules absent. Infl composed of variously modified terminal...Browallia; Brugmansia; Brunfelsia; Capsicum; Cestrum; Petunia; Physalis; Solandra; Solanum; Streptosolen2005
14 Activation-dependent redistribution of the adhesion plaque protein, talin, in intact human plateletsTalin is a high molecular weight protein localized at adhesion plaques in fibroblasts. It binds vinculin and integrin and appears to participate in generating a transmembrane connection between the extracellular matrix and the cytoskeleton.Talin1989
15 Vesicular-arbuscular mycorrhizae in two tropical monodominant treesMycorrhizae, symbioses between plant roots and fungi, are in virtually all terrestrial plant ecosystems. Substantial evidence indicates that mycorrhizal associations are beneficial to both partners. In most systems, the fungus benefits the host plant by effectively scavenging nutrients and in return...Monodominance; Ectomycorrhizae; Flooding; Neotropics; Vesicular-arbuscular mycorrizae; Mora excelsa; Prioria copaifera1997
16 Water and nitrogen uptake patterns following moisture pulses in a cold desert communityVariation in the ability to utilize pulses of both water and nitrogen (N) is one possible mechanism allowing the coexistence of species in the cold desert community on the Colorado Plateau. We simulated 25-mm precipitation events and used stable isotope tracers (2H and 15N) to follow water and N upt...Colorado Plateau; Desert perennials; Nitrogen uptake patterns; Pulse utilization; Resource partitioning; Stable isotopes; Water uptake patterns2000
17 Guidance of neuronal growth cones in the grasshopper embryo. II. Recognition of a specific axonal pathway by the aCC neuronIn the previous paper, we experimentally analyzed the selective affinity of the pCC growth cone for the MP1/dMP2 fascicle in the grasshopper embryo. Here we describe a similar experimental analysis demonstrating the selective affinity of the aCC growth cone for the U fascicle. These results support...Axon; Cell; Fascicle1986
18 Rates of herbivory on different tropical treesRates of herbivory on marked young and mature leaves from saplings of 21 canopy tree species were measured in the wet and dry seasons. Species were classified into two life history groups: persistent species which are found throughout the shaded understory, and pioneer species which only become e...Herbivory; Grazing damage; Tropical trees; Pioneer species; Trees -- Tropics1982
19 Use of lung transplantation survival models to refine patient selection in cystic fibrosisLung transplantation in cystic fibrosis may improve survival for patients with low 5-year predicted survival.
