Impact Of Carbon Sources On Growth And Oxalate Synthesis By The Phytopathogenic Fungus Sclerotinia Sclerotiorum, Bryan J. Culbertson, Jaymie Krone, Erastus Gatebe, Norbert C. Furumo, Steven L. Daniel
Impact Of Carbon Sources On Growth And Oxalate Synthesis By The Phytopathogenic Fungus Sclerotinia Sclerotiorum, Bryan J. Culbertson, Jaymie Krone, Erastus Gatebe, Norbert C. Furumo, Steven L. Daniel
Steven L. Daniel
The impact of various supplemental carbon sources (oxalate, glyoxylate, glycolate, pyruvate, formate, malate, acetate, and succinate) on growth and oxalate formation (i.e., oxalogenesis) by Sclerotinia sclerotiorum was studied. With isolates D-E7, 105, W-B10, and Arg-L of S. sclerotiorum, growth in an undefined broth medium (0.1% soytone; pH 5) with 25 mM glucose and 25 mM supplemental carbon source was increased by the addition of malate and succinate. Oxalate accumulation occurred in the presence of glucose and a supplemental carbon source, with malate, acetate, and succinate supporting the most oxalate synthesis. With S. sclerotiorum Arg-L, oxalate-to-biomass ratios, an indicator of oxalogenic …

We prove that if $F$ is a finitely generated abelian group of orientation preserving $C^1$ diffeomorphisms of $R^2$ which leaves invariant a compact set then there is a common fixed point for all elements of $F.$ We also show that if $F$ is any abelian subgroup of orientation preserving $C^1$ diffeomorphisms of $S^2$ then there is a common fixed point for all elements of a subgroup of $F$ with index at most two.

Sources Of Wood And Wood Residues For Energy Production In Indiana, Isaac Slaven, Eva Haviarova, Klein Ileleji
Sources Of Wood And Wood Residues For Energy Production In Indiana, Isaac Slaven, Eva Haviarova, Klein Ileleji
Isaac Slaven
As energy prices rise and there is a push for energy to be produced from renewable resources, the contribution of Indiana’s corn and soybean industry often overshadows the impact that wood residues can have in response to these demands. Reports show that the wood products industry is the largest, by paid wages, of any agricultural industry in Indiana and employs 47,000 Hoosiers (Biocrossroads 2005). In fact, Indiana has more than 4.5 million acres of forest land (USDA FS, FIA 2005) compared to about 12.3 million acres of crop land (NASS 2006). In addition to the millions of acres of forestland, …

Impact Of Nutritional Supplements And Monosaccharides On Growth, Oxalate Accumulation, And Culture Ph By Sclerotinia Sclerotiorum, Steven L. Daniel, Bryan J. Culbertson, Norbert C. Furumo
Impact Of Nutritional Supplements And Monosaccharides On Growth, Oxalate Accumulation, And Culture Ph By Sclerotinia Sclerotiorum, Steven L. Daniel, Bryan J. Culbertson, Norbert C. Furumo
Steven L. Daniel
Sclerotinia sclerotiorum D-E7 was studied to determine the impact of nutritional supplements and monosaccharides on growth, oxalate accumulation, and culture pH in broth media (initial pH c. 5). Cultures with 0.1% nutritional supplement (tryptone, yeast extract, or soytone) yielded minimal growth, 2–3 mM oxalate, and a final culture pH of 4.2–4.8. In contrast, cultures with 0.1% nutritional supplement and 25 mM glucose yielded significant growth, minimal oxalate (<1 mM), and a final culture pH of 2.8–3.7. Similar trends were observed when glucose in 0.1% soytone cultures was replaced with 25 mM d-mannose, l-arabinose, or d-xylose. With 1% soytone-25 mM glucose cultures, growth and oxalate accumulation (∼21 mM) occurred with little change in initial pH. This was not the case with 1% soytone-250 mM glucose cultures; increased glucose levels resulted in a decrease in oxalate accumulation (∼7 mM) and in final culture pH (3.4). Time-course studies with these cultures revealed that oxalate accumulation was suppressed during growth when the culture pH dropped to <4. Overall, these results indicate that (1) the decrease in external pH (i.e. acidification) was independent of oxalate accumulation and (2) acidification coupled to glucose-dependent growth regulated oxalate accumulation by Sclerotinia sclerotiorum.

The Distribution Of Apolipoprotein E In Mouse Olfactory Epithelium, Britto P. Nathan, Sreenivas Nannapaneni, Salina Gairhe, Ikemefuna Nwosu, Robert G. Struble
Britto P. Nathan
Previous studies from our laboratory suggest that apolipoprotein (apoE), a lipid transporting protein, facilitates olfactory nerve regeneration. We have shown that apoE is enriched in the olfactory nerve and around the glomeruli of the olfactory bulb (OB). The studies reported herein were undertaken to identify possible sources of apoE in the olfactory epithelium (OE). Immunoblotting results revealed apoE expression in the OE of wild-type (WT) mice, but not in apoE deficient/knockout (KO) mice. Immunohistochemical studies revealed that the perikarya and processes of sustentacular (Sus) cells expressed apoE-like immunoreactivity. Minimal neuronal apoE immunostaining was seen, although apoE was observed in the …

Native And Exotic Plant Species Exhibit Similar Population Dynamics During Succession, Scott J. Meiners
Native And Exotic Plant Species Exhibit Similar Population Dynamics During Succession, Scott J. Meiners
Scott J. Meiners
A growing body of literature has led to the debate in invasion biology whether exotic species perform within communities differently than native taxa due to inherent advantages. To address this issue, the population dynamics of native and exotic plant species were assessed from a 48-year record of permanent plot data from the Hutcheson Memorial Forest Center (New Jersey, USA) to determine rate of increase, lag time, maximum frequency, and the year of peak frequency. Overall, native and exotic species exhibited very similar population dynamics. Rates of increase and length of lag times were similar between native and exotic taxa but …
Apoptosis Of Dedifferentiated Hepatoma Cells Is Independent Of Nf-Jb Activation In Response To Lps, M. Ryan Reidy, Janette Ellis, Erin A. Schmitz, David M. Kraus, Gary A. Bulla
Apoptosis Of Dedifferentiated Hepatoma Cells Is Independent Of Nf-Jb Activation In Response To Lps, M. Ryan Reidy, Janette Ellis, Erin A. Schmitz, David M. Kraus, Gary A. Bulla
Gary A. Bulla
Dedifferentiated hepatoma cells, in contrast to most other cell types including hepatoma cells, undergo apoptosis when treated with lipopolysaccharide (LPS) plus the protein synthesis inhibitor cycloheximide (CHx). We recently reported that the dedifferentiated hepatoma cells also exhibit a strong and prolonged NF-jB induction phenotype upon exposure to LPS, suggesting that NF-jB signaling may play a pro-survival role, as reported in several other cell systems. To test the role of NF-jB in preventing LPS-mediated apoptosis, we examined the dedifferentiated cell line M38. Results show that antioxidants strongly inhibited LPS + CHx-mediated cell death in the M38 cells, yet only modestly inhibited …
Anaerobic Oxalate Consumption By Microorganisms In Forest Soils, Steven L. Daniel, Christine Pilsl, Harold L. Drake
Anaerobic Oxalate Consumption By Microorganisms In Forest Soils, Steven L. Daniel, Christine Pilsl, Harold L. Drake
Steven L. Daniel
The microbial consumption of oxalate was examined under anaerobic conditions in soil suspensions at 15-20 degree C. With soil (horizon Ah, pH 6.4) from a beech forest, microbial consumption of added oxalate (15 mM) began after 10 days, and oxalate was totally consumed by day 20. The presence of supplemental electron donors (acetate, glucose, vanillate, or hydrogen) or electron acceptors (nitrate or sulfate) did not significantly influence anaerobic oxalate consumption, whereas supplementation of soil suspensions with CO2/bicarbonate totally repressed oxalate consumption. Thus, CO2-, nitrate- or sulfate-respiring bacteria were apparently not active in the anaerobic consumption of oxalate in these soil …
Production Of Methanethiol And Volatile Sulfur Compounds By The Archaeon ‘‘Ferroplasma Acidarmanus’’, David J. Baumler, Kai F. Hung, Kwang Cheol Jeong, Charles W. Kaspar
Production Of Methanethiol And Volatile Sulfur Compounds By The Archaeon ‘‘Ferroplasma Acidarmanus’’, David J. Baumler, Kai F. Hung, Kwang Cheol Jeong, Charles W. Kaspar
Kai F. Hung
Acidophiles are typically isolated from sulfaterich ecological niches yet the role of sulfur metabolism in their growth and survival is poorly defined. Studies of heterotrophically grown ‘‘Ferroplasma acidarmanus’’ showed that its growth requires a minimum of 100 mM of a sulfate-containing salt. Headspace gas analyses by GC/ MS determined that the volatile sulfur compound emitted by active ‘‘F. acidarmanus’’ cultures is methanethiol. In ‘‘F. acidarmanus’’ cultures grown either heterotrophically or chemolithotrophically, methanethiol was produced constitutively. Radiotracer studies with 35S-labeled methionine, cysteine, and sulfate showed that all three were used in methanethiol production. Additionally, 3H-labeled methionine was incorporated into methanethiol and …

Over-Expression Of Udp-Glucose Pyrophosphorylase In Hybrid Poplar Affects Carbon Allocation, Heather D. Coleman, Thomas Canam, Kyu-Young Kang, David D. Ellis, Shawn D. Mansfield
Thomas Canam
The effects of the over-expression of the Acetobacter xylinum UDP-glucose pyrophosphorylase (UGPase) under the control of the tandem repeat Cauliflower Mosaic Virus promoter (2335S) on plant metabolism and growth were investigated in hybrid poplar (Populus alba3grandidentata). Transcript levels, enzyme activity, growth parameters, leaf morphology, structural and soluble carbohydrates, and soluble metabolite levels were quantified in both transgenic and wild-type trees. Transgenic 2335S::UGPase poplar showed impaired growth rates, displaying reduced height growth and stem diameter. Morphologically, 2335S::UGPase trees had elongated axial shoots, and leaves that were substantially smaller in size when compared with wild-type trees at equivalent developmental stages. Biochemical analysis …
Physical Contests For Females In The Japanese Beetle, Popillia Japonica, Paul Switzer, Kipp C. Kruse
Physical Contests For Females In The Japanese Beetle, Popillia Japonica, Paul Switzer, Kipp C. Kruse
Paul V. Switzer
We conducted field observations of physical competition for mates, in which a single male attempts to usurp a female from another male, in male Japanese beetles, Popillia japonica Newman (Coleoptera; Scarabaeidae). Physical contests for mates were relatively rare, but when they occurred the challenger male was able to successfully takeover females by dislodging the previously paired resident male in only 18% of contests, suggesting that a substantial prior residency advantage exists in this species. Challenger males that were successful in takeover attempts were significantly larger than the resident male. In contrast, no size pattern was found between intruding males and …
The Effect Of Male And Female Body Size On Mating Behavior Of Male Fairy Shrimp, Eubranchipus Neglectus, Craig Feigenbaum, Paul V. Switzer
The Effect Of Male And Female Body Size On Mating Behavior Of Male Fairy Shrimp, Eubranchipus Neglectus, Craig Feigenbaum, Paul V. Switzer
Paul V. Switzer
We studied size-related mating patterns in the freshwater fairy shrimp Eubranchipus neglectus in the laboratory. Males were provided with relatively small or large females that they could only sense by vision. We recorded the number of times a male pursued the female (“follows”), the duration of these follows, and the number of times a male attempted to grasp the female. Relatively large males performed more mating behavior than relatively small males. Furthermore, males (regardless of their own size) exhibited more mating behavior towards large than small females. They followed large females more frequently, attempted to grasp large females more often, …

The Cynipoid Genus Paramblynotus: Revision, Phylogeny, And Historical Biogeography (Hymenoptera, Liopteridae), Zhiwei Liu, Fredrik Ronquist, Goeran Nordlander
Zhiwei Liu
The genus Paramblynotus is the most species-rich genus of the so-called macrocynipoids, the large cynipoid parasitoids of wood-boring and cone-boring insect larvae. The species range in size from some of the largest to the smallest macrocynipoids, comparable in size to microcynipoids. Paramblynotus members occur on all continents except Europe and Australia, with most species being tropical or subtropical. The biology is poorly known but a few observations indicate that the species are parasitoids of beetle larvae. In this monographic revision of the genus, we present a species-level cladistic analysis based on qualitative and quantitative features of the external morphology. For …
