Hyaluronan Synthase Of Chlorella Virus Pbcv-1, Paul L. Deangelis, Wei Jing, Michael V. Graves, Dwight E. Burbank, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Sequence analysis of the 330-kilobase genome of the virus PBCV-1 that infects a chlorella-like green algae revealed an open reading frame, A98R, with similarity to several hyaluronan synthases. Hyaluronan is an essential polysaccharide found in higher animals as well as in a few pathogenic bacteria. Expression of the A98R gene product in Escherichia coli indicated that the recombinant protein is an authentic hyaluronan synthase. A98R is expressed early in PBCV-1 infection and hyaluronan is produced in infected algae. These results demonstrate that a virus can encode an enzyme capable of synthesizing a carbohydrate polymer and that hyaluronan exists outside of …

Tb167: Management And Winter Hardiness Of Hairy Vetch In Maine, Jean-Luc Jannink, Laura C. Merrick, Matt Liebman, Elizabeth A. Dyck

Technical Bulletins

The research presented here describes a set of three different experiments that sought to establish appropriate management practices for hairy vetch in Maine, and to determine whether variability for winter hardiness exists among germplasm available commercially or from gene banks. Specific objectives of the first experiment were to evaluate effects of planting date and companion crop on crop and weed dry weight and total above-ground N content, at two sites differing in drainage. In a second experiment, the winter hardiness of hairy vetch from six commercial sources and the effect of a rye companion crop on hardiness were evaluated. In …

Pb576 Wheat Production In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Tennessee’s climate is well suited for the production of high-quality, lowprotein, soft red winter wheat. This wheat is in demand by the flour milling industry and well-established local markets are adequate.

Tennessee-produced soft wheat is used primarily for milling general purpose or family flours, pastry flours and cake flours. Very little of Tennessee’s wheat is used for livestock feed, except as byproducts of the milling industry.

Winter wheat is a cool-season crop and can be grown successfully in all counties of the state. Soft red winter wheat varieties recommended and commonly grown in Tennessee have adequate winter hardiness to survive …

Scanning Electron Microscopy, Histological, And Tissue Culture Studies Of Powdery Mildews Infecting Dogwoods, Leigh Ann Klein

Masters Theses

Powdery mildew has become a common and widespread foliar disease of dogwoods. Microsphaera pulchra Cooke and Peck, and Phyllactinia guttata (Wallr.: Fr.) Lev. are two causal agents of powdery mildew on dogwood species in eastern North America. A clear understanding of the host-pathogen relationship between these fungi and their host must be obtained to advance research in disease management and resistance breeding.

A necessary step in studying a disease is to identify the causal agent. Leaves of C. florida 'Cherokee Sunset' and C. amomum (silky dogwood) were observed under a compound microscope to determine causal agents of powdery mildew based …

Nebraska Range Shortcourse: A Successful Approach To Continuing Education, Daniel R. Vaughn, Anthony D. Watson, Lowell E. Moser, Walter H. Schacht

Department of Agronomy and Horticulture: Faculty Publications

Casual visitors to Nebraska rarely see the diversity of the 23 million acres of its rangeland. The state boasts of its nonparalleled range beef cattle industry which relies heavily on the Sandhills, a seemingly endless expanse of grass-covered dunes. In sharp contrast to the Sandhills, however, is a wide array of landscapes including the pine ridge of northern Nebraska, the sagebrush grassland of the southwestern region, the shortgrass prairie of the panhandle, the highly-dissected loess hills, and wooded river valleys. These landscapes offer a complex mixture of habitats, recreational opportunities, rangeland products, and management challenges. People with varied education and …

Pb1600 Control Of Voles In No-Till Corn, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Voles have historically been a problem for farmers using minimum and no-till technologies to establish field corn. As land enrolled in the Conservation Reserve Program (CRP) is returned to row crops, this problem is expected to increase. Retaining established cover by no-till farming decreases erosion, improves water quality, increases wildlife habitat and conserves moisture when compared to conventional tillage practices. However, voles that have established colonies and flourished beneath the cover established under CRP, crop residue or hay crops can devastate crop plantings. Stand reductions of 80-100 percent have been reported in no-till corn where vole numbers are high.

Growing Degree-Days: One Equation, Two Interpretations, Gregory S. Mcmaster, Wallace Wilhelm

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

Heat units, expressed in growing degree-days (GDD), are frequently used to describe the timing of biological processes. The basic equation used is GDD = [(T_MAX + T_MIN)/2] - T_BASE where T_MAX and T_MIN are daily maximum and minimum air temperature, respectively, and T_BASE is the base temperature. Two methods of interpreting this equation for calculating GDD are: (1) if the daily mean temperature is less than the base, it is set equal to the base temperature, or (2) if T_MAX or T_MIN < T_BASE they are reset equal to T …

Morphological Development Of Switchgrass As Affected By Planting Date, Alexander J. Smart, Lowell E. Moser

Department of Agronomy and Horticulture: Faculty Publications

Late-spring and early-summer plantings of warm-season grasses often fail, due to dry soil conditions and competition from annual grass and broadleaf weeds. The objective of this study was to compare the morphological development of switchgrass (Panicum virgatum L.) planted in early, mid, and late spring in eastern Nebraska. This study was conducted in 1994 and 1995 at Lincoln, NE, on a Kennebec silt loam (fine-silty, mixed, mesic Cumulic Hapludolls). 'Blackwell' and 'Trailblazer' switchgrass were planted in mid-March, late April, and late May using a single-row, precision grass-seed cone planter to a depth of 0.6 to 1.3 cm at 98 …

Identification Of The Wheat Curl Mite As The Vector Of The High Plains Virus Of Corn And Wheat, Dallas L. Seifers, Tom L. Harvey, T. J. Martin, Stanley G. Jensen

Department of Plant Pathology: Faculty Publications

Wheat with virus-like symptoms (extracts containing a 33-kDa protein in sodium dodecyl sulfate- polyacrylamide gel electrophoresis, negative in enzyme-linked immunosorbent assay to wheat streak mosaic virus, and not infectious in a backassay to other wheat) reacted positively to antiserum made against a protein purified from symptomatic corn infected with the High Plains virus (HPV), indicating a serological relationship between the corn and wheat pathogens. The wheat curl mite (WCM, Aceria tosichella Keifer) was identified as the vector of the virus and caused persistent infection of barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) in greenhouse experiments. The …
