Nitrogen Capture By Grapevine Roots And Arbuscular Mycorrhizal Fungi From Legume Cover-Crop Residues Under Low Rates Of Mineral Fertilization, Xiaomei Cheng, Amy Euliss, Kendra Baumgartner
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The influence of mineral fertilization on root uptake and arbuscular mycorrhizal fungi-mediated 15N capture from labeled legume (Medicago polymorpha) residue was examined in winegrapes (Vitis vinifera) in the greenhouse, to evaluate compatibility of fertilization with incorporation of cover-crop residue in winegrape production. Plants grown in marginal vineyard soil were either fertilized with 0.25× Hoagland’s solution or not. This low fertilization rate represents the deficit management approach typical of winegrape production. Access to residue in a separate compartment was controlled to allow mycorrhizal roots (roots + hyphae), hyphae (hyphae-intact), or neither (hyphae-rotated) to proliferate in the …

Endocrine Responses Of Fast- And Slow-Growing Families Of Channel Catfish, Brian C. Peterson, Brian C. Small, Geoffrey C. Waldbieser, Brian G. Bosworth
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Sixty-eight families of USDA303 channel catfish Ictalurus punctatus were evaluated for growth performance for 30 d. The fastest- and slowest-growing catfish families were further evaluated to examine the hypothesis that genes or gene products associated with the growth regulatory and stress axes can be used to describe differences in growth performance. Research examined mRNA levels of genes involved in the growth hormone–insulin-like growth factor (GH–IGF) network in fast- (family A) and slow-growing (family H) USDA303 catfish. Fish (59.0 ± 2.4 g) were fed for 7 weeks, weighed, and had tissues for RNA extraction. The remaining fish were subjected to an …
History And Ecological Basis For Areawide Pest Management, Norman C. Elliott, David W. Onstad, Michael J. Brewer
History And Ecological Basis For Areawide Pest Management, Norman C. Elliott, David W. Onstad, Michael J. Brewer
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The traditional approach to pest management is to treat the crop or commodity in a particular management unit before an economically significant infestation of the pest has developed. Determining the need to take corrective action is based on the economic threshold concept, which forms the basis of most integrated pest management programmes (Metcalf and Luckman, 1975). Areawide pest management (AWPM) can be contrasted with traditional pest management in that pest management tactics are used over a broad spatial area, often treating the whole area simultaneously to maintain the pest below economic levels or, in some cases, completely eradicate it. A …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Salt cedar (Tamarix spp. (Tamaricaceae: Tamaricales)) is a group of exotic shrubs to small trees that have invaded many riparian areas and lake shores across western North America. Of the 54 species known worldwide (Baum, 1967, 1968), ten species of salt cedars have been introduced into the USA (Crins, 1989), primarily from their countries of origin across Europe and Central Asia. They are also native in Africa and the Indian subcontinent of Asia. No species from the entire family Tamaricaceae are native to North America, and only a restricted group of six species of more distantly related …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The overall goal of our research is to characterize and identify gene expression profiles of porcine hepatic cells. In this study, we have prepared two-dimensional electrophoresis maps of cytosol and membrane fractions from freshly prepared hepatocytes which were pooled from three crossbred pigs (35–69 kg). Following isoelectric focusing with three pH range immobilized pH gradient strips (pH 3–6, 5–8 and 7–10) and staining the second dimension gels with colloidal Coomassie blue, 728 protein spots were picked and digested with trypsin. Extracted tryptic peptides were initially subjected to matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI–TOF-MS) analysis for identification of proteins …
Nuclear Targeting By Fragmentation Of The Potato Spindle Tuber Viroid Genome, Asta Abraitiene, Yan Zhao, Rosemarie Hammond
Nuclear Targeting By Fragmentation Of The Potato Spindle Tuber Viroid Genome, Asta Abraitiene, Yan Zhao, Rosemarie Hammond
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Transient expression of engineered reporter RNAs encoding an intron-containing green fluorescent protein (GFP) from a Potato virus X-based expression vector previously demonstrated the nuclear targeting capability of the 359 nucleotide Potato spindle tuber viroid (PSTVd) RNA genome. To further delimit the putative nuclear-targeting signal, PSTVd subgenomic fragments were embedded within the intron, and recombinant reporter RNAs were inoculated onto Nicotiana benthamiana plants. Appearance of green fluorescence in leaf tissue inoculated with PSTVd-fragment-containing constructs indicated shuttling of the RNA into the nucleus by fragments as short as 80 nucleotides in length. Plant-to-plant variation in the timing of intron removal and subsequent …

Hessian Fly, Jeffrey J. Stuart, Ming-Shun Chen, Marion O. Harris
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The Hessian fly (Mayetiola destructor) is a gall-forming insect (Harris et al. 2006) with several attributes that make it suitable for genetic analysis: a short life cycle (30 days), a small genome (158 Mb) (Johnston et al. 2004), and polytene chromosomes. The reproductive biology and behavior of the insect also make it an attractive model (Harris and Rose 1989,1990; Bergh et al. 1990; Kanno and Harris 2000; Morris et al. 2000; Harris et al. 2001). Compared to most plant-feeding insects, Hessian flies can be reared in a small space. Unlike gall-forming aphid species, the Hessian fly is always …

There has been an increase in the use of formal approaches to environmental management. Jakeman and Letcher (2003) and Jakeman et al. (2006) have demonstrated the importance of integrated models as a means of assessing the response of environmental systems to proposed enlargement options. Gunderson and Holling (2000), Cowie and Borrett (2005), Curtis et al. (2005) and Pahl-Wostl (2005) have highlighted the need for the incorporation of social and institutional aspects into decision-making processes.

Desert Rocks – A Habitat Which Supports Many Species That Were New To Science In The Last 40 Years, Avinoam Danin
Turkish Journal of Botany
Hard limestone, dolomite, sandstone, and granite constitute, under certain conditions, smooth-faced outcrops in desert areas of SW Asia. This habitat supports the most rare plant species in the desert including most of the desert endemics of Israel, Sinai, and Jordan. The smooth-faced outcrops efficiently contribute runoff water to the rock crevices and events when water is available for plant utilisation take place at a higher frequency than in the other habitats in the desert. In many sites plants are isolated and protected by impermeable rocks from competition from other plants. The rare and special plants found in this habitat include …

Challenges Of In Situ Conservation Of Crop Wild Relatives, Vernon Hilton Heywood
Challenges Of In Situ Conservation Of Crop Wild Relatives, Vernon Hilton Heywood
Turkish Journal of Botany
Crop wild relatives (CWRs) will gain in importance as changing climates put both traditional and advanced cultivars under increasing stress, leading to a need for plant breeding to produce new varieties able to grow under the new climate regimes. Traditionally, the approach to the conservation of CWRs has been ex situ - the collection and maintenance of seed accessions in national, regional, and international germplasm banks, supplemented by field genebanks for species with recalcitrant seeds. More recently the need to maintain CWRs in their natural habitats (in situ) has been advocated. This is very different from on-farm conservation of traditional …

Recent Advances In Medicago Truncatula Genomics, Jean-Michel Ané, Hongyan Zhu, Julia Frugoli
Plant and Soil Sciences Faculty Publications
Legume rotation has allowed a consistent increase in crop yield and consequently in human population since the antiquity. Legumes will also be instrumental in our ability to maintain the sustainability of our agriculture while facing the challenges of increasing food and biofuel demand. Medicago truncatula and Lotus japonicus have emerged during the last decade as two major model systems for legume biology. Initially developed to dissect plant-microbe symbiotic interactions and especially legume nodulation, these two models are now widely used in a variety of biological fields from plant physiology and development to population genetics and structural genomics. This review highlights …

Effects Of Storage Temperature And Duration On The Milling Properties Of Rice, Tanya Pereira, Nora Cooper, Terry Siebenmorgen
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
To maximize rice quality, it is essential to quantify the various factors that affect milling properties of rice. Rice aging, a process during which rice undergoes a series of chemical and physicochemical changes, affects head rice yield (HRY) and the rate at which HRY changes with degree of milling (DOM). This study examined effects of storage duration (0, 2, and 4 months) and storage temperature (4, 21, and 35°C) on milling properties of ‘Wells’ (long-grain) and ‘Jupiter’ (medium-grain) rice cultivars. In general, HRY increased with storage duration, most significantly for Wells cultivar. Millability curves were developed by plotting HRY vs. …

The Effect Of Austrian Winter-Pea Cover Crop And Cow-Pea Companion Crop On Corn Yield, Matthew Marsh, David Longer, Vaughn Skinner
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Leguminous cover crops have the potential to combat the rising input cost of commercial nitrogen (N) fertilizers. This experiment examines benefits of implementing a leguminous cover and/or companion crop into a corn production system. Legumes biologically fix nitrogen from the atmosphere, adding to the nitrogen content of the soil. In this experiment Austrian winter peas (Pisum arvense) (AWP) were used as the leguminous cover crop and cowpeas (Vigna unguiculata) were used as the companion crop. A two year experiment was carried out in which winter peas were planted on half the field in the fall and allowed to grow until …
