Department of Plant Pathology: Faculty Publications
Aspergillus fumigatus is an aggressive opportunistic pathogen of humans as well as a major allergen. Environmental sensing and retrieving essential nutrients from the environment are general metabolic traits associated with the growth of this saprophytic fungus. Two important mediators of calcium signals in eukaryotic cells are the Ca2+-binding protein calmodulin and the Ca2+/calmodulin-dependent phosphatase calcineurin. Calcineurin is a heterodimer that consists of a catalytic subunit A and a Ca2+/calmodulin binding unit. We deleted the A. fumigatus calA gene, which encodes the calcineurin A catalytic subunit, and demonstrated that this gene is not essential in …

Alfalfa Hay For Horses, Robert Coleman
Alfalfa Hay For Horses, Robert Coleman
Kentucky Alfalfa and Stored Forage Conference
Horses are designed to eat forage and quality forage is the basis for the feeding programs of all classes of horse. However, when one considers hay as that basic forage, what criteria are used to describe quality horse hay? In general terms, quality horse hay should supply needed nutrients, be palatable and should be free of anything harmful to the horse.
How The Alfalfa Plant Grows: Impact On Management, S. Ray Smith
How The Alfalfa Plant Grows: Impact On Management, S. Ray Smith
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is the premier forage crop with high yield, high forage quality, season long productivity, drought tolerance, and extended stand life. Alfalfa requires intensive management to insure that yield, quality, and stand life are maximized. It should be planted on deep, well drained soils and maintained with optimal fertilizer inputs. It also requires adequate rest periods between cutting for hay or grazing. Alfalfa can be prone to significant insect damage and stands may require insecticide treatments. There are many details to successfully managing an alfalfa stand, but if you understand how the plant grows then you will better understand the …

Greater Diversity Of Shiga Toxin-Encoding Bacteriophage Insertion Sites Among Escherichia Coli O157:H7 Isolates From Cattle Than In Those From Humans, Thomas E. Besser, Nurmohammad Shaikh, Nicholas J. Holt, Phillip I. Tarr, Michael E. Konkel, Preeti Malik-Kale, Coilin W. Walsh, Thomas S. Whittam, James L. Bono
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
E. coli O157:H7, a zoonotic human pathogen for which domestic cattle are a reservoir host, produces a Shiga toxin(s) (Stx) encoded by bacteriophages. Chromosomal insertion sites of these bacteriophages define three principal genotypes (clusters 1 to 3) among clinical isolates of E. coliO157:H7. Stx-encoding bacteriophage insertion site genotypes of 282 clinical and 80 bovine isolates were evaluated. A total of 268 (95.0%) of the clinical isolates, but only 41 (51.3%) of the bovine isolates, belonged to cluster 1, 2, or 3 (P < 0.001). Thirteen additional genotypes were identified in isolates from both cattle and humans (four genotypes), from only cattle (seven genotypes), or from only humans (two genotypes). Two other markers previously associated with isolates from cattle or with clinical isolates showed similar associations with genotype groups within bovine isolates; the tir allele sp-1 and the Q933W allele were under- and overrepresented, respectively, among cluster 1 to …
Root Lesion And Burrowing Nematodes In Western Australian Cropping Systems, Vivien Vanstone
Root Lesion And Burrowing Nematodes In Western Australian Cropping Systems, Vivien Vanstone
Bulletins 4000 -
Nematodes are common soil pests that feed on the roots of a wide range of crop plants in all agricultural areas of Western Australia, irrespective of soil type and rainfall. Nematodes multiply on susceptible hosts. Consequently, as nematode populations increase, crop production is limited. Cereal yield losses due to nematodes in Western Australia are in the order of 5 to 15 per cent per annum, but individual losses as high as 40 per cent have been recorded.

Forage Quality: What Is It? What Can We Do About It? And, Will It Pay?, Garry D. Lacefield
Forage Symposium at the Kentucky Cattlemen’s Convention
Profitable livestock production almost always requires a forage program that will supply large quantities of adequate quality, homegrown feed. A major percentage of the feed units for beef (83%) and dairy cattle (61%) come from forages. In addition, forages supply an estimated 91%, 72%, 15% and 99% of the nutrients consumed by sheep and goats, horses, swine, and wildlife, respectively.

How I Produce, Manage And Market Forages, Bill Payne
Forage Symposium at the Kentucky Cattlemen’s Convention
I would like to amend the title to: “How I Produce, Manage and Market Forages, Profitably.” My experience has led me to believe that keeping things simple has allowed me to focus better and that has led to profitability. This has led me to make every effort to reduce my reliance on machinery and to allow the cows to do the work. I focus on maximizing forage utilization and minimizing the number of days of feeding stored feeds.

Bulletins 4000 -
This manual is part of a joint project between the Department of Agriculture and Food WA and the South East Premium Wheat Growers Association (SEPWA) with funding from the Grains Research and Development Corporation (GRDC). Growers in the Esperance port zone have been concerned with declining protein levels in wheat and its impact on farm returns as well as strong messages from processors of Esperance wheat that they require higher protein in the wheat they mill and process.
The project entailed grower involvement in designing and executing field scale experiments using farmer machinery, grower workshops, field days and meetings to …

Rational Risk/Benefit Analysis Of Genetically Modified Crops, Stanley P. Kowalski
Law Faculty Scholarship
Safety concerns over the use of molecular biotechnology in the improvement of crops has generated substantial, heated and confusing debates, often driven by ideology and hysterics. Modification of crops is not new, and biotechnology (in its broadest sense) has been used for over a century to accelerate the development of new crops for food, feed and fibre, so as to meet the demands of a growing global community. The introduction of crops developed via molecular biotechnology [Genetically Modified Crops (GMCs)] represents the latest step in this inexorable innovative progression of technology. However, misinformed concern has led to a broad embrace …

There are over 20 growers who produce cucumbers under protected cultivation in Western Australia, ranging from Manjimup in the South-West to Geraldton and Carnarvon. They mainly grow these crops hydroponically in greenhouses. There is also some production under shadecloth and some crops are grown in soil. There are two types of cucumbers grown under protected cultivation. The Continental or burpless cucumber is the main type of cucumber and has long fruit, whereas the Lebanese (mini) cucumber has shorter fruit. Compared with field cucumbers, these two types are seedless and do not require pollination to produce fruits. To ensure they are …

Regulation Of Hyphal Morphogenesis By Cdc42 And Rac1 Homologues In Aspergillus Nidulans, Aleksandra Virag, Maurice P. Lee, Haoyu Si, Steven D. Harris
Department of Plant Pathology: Faculty Publications
The ability of filamentous fungi to form hyphae requires the establishment and maintenance of a stable polarity axis. Based on studies in yeasts and animals, the GTPases Cdc42 and Rac1 are presumed to play a central role in organizing the morphogenetic machinery to enable axis formation and stabilization. Here, we report that Cdc42 (ModA) and Rac1 (RacA) share an overlapping function required for polarity establishment in Aspergillus nidulans. Nevertheless, Cdc42 appears to have a more important role in hyphal morphogenesis in that it alone is required for the timely formation of lateral branches. In addition, we provide genetic evidence …

Department of Plant Pathology: Faculty Publications
A screen for antifungal compounds from Lysobacter enzymogenes strain C3, a bacterial biological control agent of fungal diseases, has previously led to the isolation of heat-stable antifungal factor (HSAF). HSAF exhibits inhibitory activities against a wide range of fungal species and shows a novel mode of antifungal action by disrupting the biosynthesis of a distinct group of sphingolipids. We have now determined the chemical structure of HSAF, which is identical to that of dihydromaltophilin, an antifungal metabolite with a unique macrocyclic lactam system containing a tetramic acid moiety and a 5,5,6-tricyclic skeleton. We have also identified the genetic locus responsible …

Early Investments In Soil Conservation Research Continues To Provide Dividends, J. E. Gilley, D. C. Flanagan
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Current soil conservation programs are built upon an established research legacy. Hugh H. Bennett, chief of the USDA Soil Conservation Service from 1935 to 1951, was instrumental in the establishment of a network of 35 soil conservation experiment stations (SCES). Research projects were initiated at the SCES in the 1930s to investigate the principal factors causing erosion and to identify the most effective and practical methods of controlling soil loss from agricultural areas. Information obtained from the SCES, and selected other locations, was assembled at the National Runoff and Soil Loss Data Center (NRSLDC) established on the campus of Purdue …

Department of Agronomy and Horticulture: Faculty Publications
Weeds compete with crops for light, soil water, and nutrients. Nitrogen (N) is the primary limiting soil nutrient. Forecasting the effects of N on growth, development, and interplant competition requires accurate prediction of N uptake and distribution within plants. Field studies were conducted in 1999 and 2000 to determine the effects of variable N addition on monoculture corn and velvetleaf N uptake, the relationship between plant N concentration ([N]) and total biomass, the fraction of N partitioned to leaves, and predicted N uptake and leaf N content. Cumulative N uptake of both species was generally greater in 2000 than in …

Finding Value In Switchgrass Today Through Cattle, John A. Guretzky
Finding Value In Switchgrass Today Through Cattle, John A. Guretzky
Department of Agronomy and Horticulture: Faculty Publications
Switchgrass has future potential in the Southern Plains as a dedicated cellulosic biofuels crop. In the near and intermediate terms, an economically viable use for switchgrass needs to be found. In May 2007, the Noble Foundation Agricultural Division successfully established a 30-acre field of switchgrass at the Red River Demonstration and Research Farm. Beginning in April 2008, we will evaluate the utilization and value of switchgrass for stocker cattle. Switchgrass may have value for stockers because of its early spring availability, high yields, perennial life form, wide adaptability and low fertilization requirements.
Second-year stands of switchgrass become available for grazing …
