Multi-Trophic Level Interactions In A Cassava-Maize Mixed Cropping System In The Humid Tropics Of West Africa, F. Schulthess, A. Chabi-Olaye, S. Gounou

All Peer-Reviewed Publications

Multi-trophic level interactions in a mixed crop, involving cassava and maize, were studied in derived-savanna in Benin, West Africa. Two trials were planted, one during the short rainy season two months before onset of the dry season and one during the long rainy season in spring. Key pests under study on maize were the noctuid Sesamia calamistis Hampson and the pyralids Eldana saccharina Walker and Mussidia nigrivenella Ragonot, and on cassava, the exotic mealybug, Phenacoccus manihoti Matile-Ferrero and its encyrtid parasitoid Apoanagyrus lopezi De Santis. Both crops received insecticide treatments to assess the crop loss by a pest species. On …

K8 And K12 Are Biotinylated In Human Histone H4, Gabriela Camporeale, Elizabeth E. Shubert, Gautam Sarath, Ronald Cerny, Janos Zempleni

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Folding of DNA into chromatin is mediated by binding to histones such as H4; association of DNA with histones is regulated by covalent histone modifications, e.g. acetylation, methylation, and biotinylation.We sought to identify aminoacid residues that are biotinylated in histone H4,and to determine whether acetylation and methylation of histones affect biotinylation. Synthetic peptides spanning fragments of human histone H4 were biotinylated enzymatically using biotinidase. Peptide-bound biotin was probed with streptavidin– peroxidase. Peptides based on the N-terminal sequence of histone H4 were effectively recognized by biotinidase as substrates for biotinylation; in contrast, peptides based on the C-terminal sequences were not biotinylated. …

Influence Of Poultry Litter On Dark Tobacco Growth And Soil Nutrient Availability, Jason Simmons

Masters Theses & Specialist Projects

Due to the relatively high value of dark tobacco compared with fertilizer costs, nitrogen is recommended at levels as high as 338 kg ha"1. Such rates of inorganic fertilizers increase the osmotic pressure of the soil solution and soil acidity, often causing reduced stands, Mn toxicity, Mo and Ca deficiencies, and reduced yield and quality of the cured leaf (Sims et al., 1984). Poultry litter utilized as a nutrient source is an inexpensive alternative to this dilemma due to its relatively neutral or alkaline composition. However, due the amount of chloride present in poultry litter, the University of Kentucky advises …

The Influence Of Environmental Temperature And Substrate Initial Moisture Content On Aspergillus Niger Growth And Phytase Production In Solid−State Cultivation, Seaborn B. Carter, Sue E. Nokes, Czarena L. Crofcheck

Biosystems and Agricultural Engineering Faculty Publications

Aspergillus niger is being used commercially for phytase production utilizing solid-state cultivation; however, no studies have been published that investigated the optimal environmental temperature and initial substrate water content to maximize fungal growth and/or phytase production. Solid-state cultivations of Aspergillus niger on wheat bran and soybean meal were conducted at three temperatures (25°C, 30°C, and 35°C) and three initial moisture contents (50%, 55%, and 60% wet basis) in a split-plot full-factorial experimental design. Fermentations were conducted for 0, 24, 48, 72, and 120 h. The containers were sampled destructively and assayed for phytase activity and glucosamine concentration as an estimate …

Prediction Of Leaf/Stem Ratio Using Near-Infrared Reflectance Spectroscopy (Nirs): A Technical Note, Alexander J. Smart, Walter H. Schacht, Lowell E. Moser, Jerry D. Volesky

Department of Agronomy and Horticulture: Faculty Publications

Leaf/stem ratio of grass stands is an important factor affecting diet selection, quality, and forage intake. Determination of leaf/stem ratio involves a labor-intensive process of hand separating leaf and stem fractions. Our objectives in this study were to evaluate leaf/stem ratio prediction using near-infrared reflectance spectroscopy (NIRS) in monocultures of big bluestem (Andropogon gerardii Vitman), switch- grass (Panicum virgatum L.), intermediate wheatgrass [Thinopyrum intermedian (Host) Barkw. & D.R. Dewey], and smooth bromegrass (Bromus inermis Leyss.). Samples of each species were hand-clipped from monocultures at four locations throughout Nebraska in the 1997 and 1998 growing seasons. Ground …

Forage & Grazing Lands: Morphological Characteristics Of Big Bluestem And Switchgrass Plants Divergently Selected For Seedling Tiller Number, Alexander J. Smart, Lowell E. Moser, Kenneth P. Vogel

Department of Agronomy and Horticulture: Faculty Publications

Selection at the seedling stage in grass breeding would be useful if seedling traits were correlated to desired agronomic traits of mature plants. Objectives of this study were to determine if seedlings from big bluestem (Andropogon gerardii Vitman) and switchgrass (Panicumvirgatum L.) populations that differ genetically in seedling tiller num- ber differ in mature plant (i) morphological characteristics, (ii) forage yield managed by a three-cut harvest system or a single end-of-season harvest, and (iii) leaf elongation rate. Field experiments were conducted on a Kennebec silt loam soil (fine-silty, mixed, superactive, mesic Cumulic Hapludolls). In addition, greenhouse studies were …

In particular, the best and most profitable forage programs have had the most thought put into them. Top producers strive to continue to improve their operations by developing strategies, practices, and procedures that will result in “GETTING MORE FROM FORAGES”.

Topcrop W.A. State Focus 2002-2003 Wheat Protein, Alison Slade, Jeremy Lemon

Bulletins 4000 -

The State Focus program is supported by the Grains Research and Development Corporation (GRDC) in conjunction with TOPCROP to provide grower groups with a new learning concept. The concept was developed in Victoria and has been adopted by South Australia and Western Australia.

Wheat protein was selected as the Western Australian State Focus in response to a wide-ranging consultation of grower groups, researchers and the TOPCROP West management group. As crop yield potential increases through matching varieties to growing season length, weed and disease control, and timely sowing systems, the crop’s demand for nitrogen increases. Unless the demand is matched …

Folate Synthesis In Plants: The P-Aminobenzoate Branch Is Initiated By A Bifunctional Paba–Pabb Protein That Is Targeted To Plastids, Gilles J. C. Basset, Eoin P. Quinlivan, Stéphane Ravanel, Fabrice Rébeillé, Brian P. Nichols, Kazuo Shinozaki, Motoaki Seki, Lori C. Adams-Phillips, James J. Giovannoni, Jesse F. Gregory Iii, Andrew D. Hanson

Center for Plant Science Innovation: Faculty Publications

It is not known how plants synthesize the p-aminobenzoate (PABA) moiety of folates. In Escherichia coli, PABA is made from chorismate in two steps. First, the PabA and PabB proteins interact to catalyze transfer of the amide nitrogen of glutamine to chorismate, forming 4-amino-4-deoxychorismate (ADC). The PabC protein then mediates elimination of pyruvate and aromatization to give PABA. Fungi, actinomycetes, and Plasmodium spp. also synthesize PABA but have proteins comprising fused domains homologous to PabA and PabB. These bipartite proteins are commonly called ‘‘PABA synthases,’’ although it is unclear whether they produce PABA or ADC. Genomic approaches identified …

Pest Management Benefits Of Compost Mulch In Apple Orchards, M. W. Brown, Thomas Tworkoski

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The effect of compost application on weed, fungal, and insect pest management in apple orchards was investigated from 1999 to 2001. Composted poultry manure was applied in June 1999 to half of two small research orchards which had previously received little or no management. The compost provided weed control for 1 year after application. There was no effect of compost on apple scab (Venturia inaequalis) infection. In a laboratory experiment, growth of the brown rot fungus (Monilinia fructicola) was significantly slower on a compost substrate than a sterilized compost substrate. The compost significantly affected arthropod abundance …

Influence Of Some Plant Extracts And Microbioagents On Some Physiological Traits Of Faba Bean Infected With Botrytis Fabae, Yehia A.G. Mahmoud, Mohsen Ebrahim, Magda M. Aly
