Impact Of Apoe Deficiency During Synaptic Remodeling In The Mouse Olfactory Bulb, Ikemefuna Nwosu, Salina Gairhe, Robert G. Struble, Britto P. Nathan
Impact Of Apoe Deficiency During Synaptic Remodeling In The Mouse Olfactory Bulb, Ikemefuna Nwosu, Salina Gairhe, Robert G. Struble, Britto P. Nathan

In this study we examined the role of apoE on the rate of synaptic recovery in the olfactory bulb (OB) following olfactory epithelium (OE) lesioning in mice. We used both immunoblotting and immunohistochemical techniques to compare the density of OB synaptophysin (Syn, a synaptic marker) in apoE-gene deficient/knockout (KO) mice and wild-type (WT) mice following OE lesion. We found that the whole bulb concentrations of Syn, measured by immunoblotting, declined sharply following injury in both WT and KO mice during the degenerative phase (3–7 days). After this initial decline, the Syn concentration gradually increased to normal levels by 56 days …
Phylogenetic Utility Of Ycf1 In Orchids: A Plastid Gene More Variable Than Matk, Kurt M. Neubig, W. Mark Whitten, Barbara S. Carlsward, Mario A. Blanco, Lorena Endara, Norris H. Williams, Michael Moore
Phylogenetic Utility Of Ycf1 In Orchids: A Plastid Gene More Variable Than Matk, Kurt M. Neubig, W. Mark Whitten, Barbara S. Carlsward, Mario A. Blanco, Lorena Endara, Norris H. Williams, Michael Moore

Plastid DNA sequences have been widely used by systematists for reconstructing plant phylogenies. The utility of any DNA region for phylogenetic analysis is determined by ease of amplification and sequencing, confidence of assessment in phylogenetic character alignment, and by variability across broad taxon sampling. Often, a compromise must be made between using relatively highly conserved coding regions or highly variable introns and intergenic spacers. Analyses of a combination of these types of DNA regions yield phylogenetic structure at various levels of a tree (i.e., along the spine and at the tips of the branches). Here, we demonstrate the phylogenetic utility …
Vegetative Anatomy Of Calypsoeae (Orchidaceae), William Louis Stern, Barbara S. Carlsward
Vegetative Anatomy Of Calypsoeae (Orchidaceae), William Louis Stern, Barbara S. Carlsward
Barbara S. Carlsward
Calypsoeae represent a small tribe of anatomically little-known orchids with a wide distribution in the Western Hemisphere. Leaves are present in all genera, except Corallorhiza and Wullschlaegelia both of which are subterranean taxa. Stomata are abaxial (ad- and abaxial in Aplectrum) and tetracytic (anomocytic in Calypso). Fiber bundles are absent in leaves of all taxa examined except Govenia tingens. Stegmata are present in leaves of only Cremastra and Govenia. Roots are velamentous, except in filiform roots of Wullschlaegelia. Vegetative anatomy supports a relationship between Wullschlaegelia and Corallorhiza but does not support the grouping of winter-leaved Aplectrum and Tipularia nor proposed …

Environmental Conditions Affect Sperm Competition Risk In Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Carissa A. Schoenick, Patrick C. Enstrom
Environmental Conditions Affect Sperm Competition Risk In Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Carissa A. Schoenick, Patrick C. Enstrom

Males of many species guard their mates to prevent rivals from usurping paternity of the potential offspring. Environmental conditions, such as temperature, may affect a male’s ability to guard a female effectively and consequently the amount of sperm competition that occurs. We tested whether temperature and light affected mating behavior in laboratory experiments on the Japanese beetle, Popillia japonica Newman, a species in which males guard females for minutes to many hours after mating. When tested in groups, under conditions of high temperature and high light, males guarded females for shorter periods of time and males and females both mated …
Molybdate Treatment And Sulfate Starvation Decrease Atp And Dna Levels In Ferroplasma Acidarmanus, Kai F. Hung
Molybdate Treatment And Sulfate Starvation Decrease Atp And Dna Levels In Ferroplasma Acidarmanus, Kai F. Hung
Kai F. Hung
Sulfate is a primary source of sulfur for most microbes and in some prokaryotes it is used an electron acceptor. The acidophile Ferroplasma acidarmanus (strain fer1) requires a minimum of 150 mM of a sulfate-containing salt for growth. Sulfate is assimilated by F. acidarmanus into proteins and reduced to form the volatile organic sulfur compounds methanethiol and dimethyldisulfide. In the absence of sulfate, cell death occurs by an unknown mechanism. In this study, cell viability and genomic DNA and ATP contents of F. acidarmanus were monitored in response to the absence of sulfate or the presence of sulfate and the …

Old Acetogens, New Light, Steven L. Daniel, Harold L. Drake, Anita S. Gößner

Acetogens utilize the acetyl-CoA Wood-Ljungdahl pathway as a terminal electron-accepting, energy-conserving, CO2-fixing process. The decades of research to resolve the enzymology of this pathway (1) preceded studies demonstrating that acetogens not only harbor a novel CO2-fixing pathway, but are also ecologically important, and (2) overshadowed the novel microbiological discoveries of acetogens and acetogenesis. The first acetogen to be isolated, Clostridium aceticum, was reported by Klaas Tammo Wieringa in 1936, but was subsequently lost. The second acetogen to be isolated, Clostridium thermoaceticum, was isolated by Francis Ephraim Fontaine and co-workers in 1942. C. thermoaceticum became the most extensively studied acetogen and …

Spatial And Temporal Expression Profiling Of Cell-Wall Invertase Genes During Early Development In Hybrid Poplar, Thomas Canam, Sarah W.Y. Mak, Shawn D. Mansfield
Thomas Canam
Cell-wall invertase genes are spatially and temporally regulated in several plant species, including Daucus carota L., Lycopersicon esculentum L. and Solanum tuberosum L. However, few studies of cell-wall invertase genes of trees have been conducted, despite the importance of trees as a source of lignocellulosic biopolymers.We identified three putative cell-wall invertase genes in hybrid poplar (Populus alba L. × grandidentata Michx.) that showed higher homology to each other than to cell-wall invertases of other dicotyledonous species, with two of the genes (Pa×gINV2 and Pa×gINV3) appearing as a genomic tandem repeat. These genes are more similar to each other than to …
