    Publication Date: 2015-10-14
    Description: For sexual communication, moths primarily use blends of fatty acid derivatives containing one or more double bonds in various positions and configurations, called sex pheromones (SPs). To study the molecular basis of novel SP component (SPC) acquisition, we used the tobacco hornworm (Manduca sexta), which uses a blend of mono-,...

    N fertilizer and harvest impacts on bioenergy crop contributions to SOC (2015)
    Wiley
    Details
    Publication Date: 2015-12-19
    Description: Belowground root biomass is infrequently measured and simply represented in models that predict landscape-level changes to soil carbon stocks and greenhouse gas balances. Yet, crop-specific responses to N fertilizer and harvest treatments are known to impact both plant allocation and tissue chemistry, potentially altering decomposition rates and the direction and magnitude of soil C stock changes and greenhouse gas fluxes. We examined switchgrass ( Panicum virgatum L.) and corn ( Zea mays L.,) yields, belowground root biomass, C, N and soil particulate organic matter–C (POM-C) in a 9-year rainfed study of N fertilizer rate (0, 60, 120, and 180 kg N ha −1 ) and harvest management near Mead, NE USA. Switchgrass was harvested with one pass in either August or post-frost and for no-till (NT) corn either 50% or no stover was removed. Switchgrass had greater belowground root biomass C & N (6.39, 0.10 Mg ha −1 ) throughout the soil profile compared to NT-corn (1.30, 0.06 Mg ha −1 ) and a higher belowground root biomass C:N ratio, indicating greater recalcitrant belowground root biomass C input beneath switchgrass. There was little difference between the two crops in soil POM-C indicating substantially slower decomposition and incorporation into SOC under switchgrass, despite much greater root C. The highest N rate decreased POM-C under both NT-corn and switchgrass, indicating faster decomposition rates with added fertilizer. Residue removal reduced corn belowground root biomass C by 37% and N by 48% and subsequently reduced POM-C by 22% compared to no residue removal. Developing productive bioenergy systems that also conserve the soil resource will require balancing fertilization that maximizes aboveground productivity but potentially reduces SOC sequestration by reducing belowground root biomass and increasing root and soil C decomposition.

    Mass hierarchy resolution in reactor anti-neutrino experiments: Parameter degeneracies and detector energy response (2013)

Zhang Determination of the neutrino mass hierarchy using a reactor neutrino experiment at ∼60  km is analyzed. Such a measurement is challenging due to the finite detector resolution, the absolute energy scale calibration, and the degeneracies caused by current experimental uncertainty of | Δ m 32 2 |.

    Nitrogen and harvest effects on soil properties under rainfed switchgrass and no-till corn over 9 years: implications for soil quality (2014)
    Wiley
    Details
    Publication Date: 2014-01-16
    Description: Nitrogen fertilizer and harvest management will alter soils under bioenergy crop production and the long-term effects of harvest timing and residue removal remain relatively unknown. Compared to no-tilled corn (NT-C, Zea mays L.), switchgrass ( Panicum virgatum L.) is predicted to improve soil properties [i.e. soil organic C (SOC), soil microbial biomass (SMB-C), and soil aggregation] due to its perennial nature and deep-rooted growth form, but few explicit field comparisons exist. We assessed soil properties over 9 years for a rainfed study of N fertilizer rate (0, 60, 120, and 180 kg N ha −1 ) and harvest management on switchgrass (harvested in August and postfrost) and NT-C (with and without 50% stover removal) in eastern NE. We measured SOC, aggregate stability, SMB-C, bulk density (BD), pH, P and K in the top 0–30 cm. Both NT-C and switchgrass increased SMB-C, SOC content, and aggregate stability over the 9 years, reflecting improvement from previous conventional management. However, the soils under switchgrass had double the percent aggregate stability, 1.3 times more microbial biomass, and a 5–8% decrease in bulk density in the 0–5 and 5–10 cm depths compared to NT-C. After 9 years, cumulative decrease in available P was significantly greater beneath NT-C (−24.0 kg P ha −1 ) compared to switchgrass (−5.4 kg P ha −1 ). When all measured soil parameters were included in the Soil Management Assessment Framework (SMAF), switchgrass improved soil quality index over time (ΔSQI) in all depths. NT-C without residue removal did not affect ΔSQI, but 50% residue removal decreased ΔSQI (0–30 cm) due to reduced aggregate stability and SMB-C. Even with best-management practices such as NT, corn stover removal will have to be carefully managed to prevent soil degradation. Long-term N and harvest management studies that include biological, chemical, and physical soil measurements are necessary to accurately assess bioenergy impacts on soils.

    Loss of a callose synthase results in salicylic acid-dependent disease resistance (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-16
    Description: Plants attacked by pathogens rapidly deposit callose, a beta-1,3-glucan, at wound sites. Traditionally, this deposition is thought to reinforce the cell wall and is regarded as a defense response. Surprisingly, here we found that powdery mildew resistant 4 (pmr4), a mutant lacking pathogen-induced callose, became resistant to pathogens, rather than more susceptible. This resistance was due to mutation of a callose synthase, resulting in a loss of the induced callose response. Double-mutant analysis indicated that blocking the salicylic acid (SA) defense signaling pathway was sufficient to restore susceptibility to pmr4 mutants. Thus, callose or callose synthase negatively regulates the SA pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nishimura, Marc T -- Stein, Monica -- Hou, Bi-Huei -- Vogel, John P -- Edwards, Herb -- Somerville, Shauna C -- New York, N.Y. -- Science. 2003 Aug 15;301(5635):969-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, Carnegie Institution, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12920300" target="_blank"〉PubMed〈/a〉

    Conjugative transfer by the virulence system of Legionella pneumophila (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-02-28
    Description: Legionella pneumophila, the causative agent of Legionnaires' pneumonia, replicates within alveolar macrophages by preventing phagosome-lysosome fusion. Here, a large number of mutants called dot (defective for organelle trafficking) that were unable to replicate intracellularly because of an inability of the bacteria to alter the endocytic pathway of macrophages were isolated. The dot virulence genes encoded a large putative membrane complex that functioned as a secretion system that was able to transfer plasmid DNA from one cell to another.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vogel, J P -- Andrews, H L -- Wong, S K -- Isberg, R R -- New York, N.Y. -- Science. 1998 Feb 6;279(5352):873-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Microbiology, Tufts University School of Medicine, Boston, MA 02111, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9452389" target="_blank"〉PubMed〈/a〉
