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 …

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 …

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 …

Dry Weight Production And Nitrogen Efficiency Traits In Kentucky Bluegrass Cultivars In Nutrient Solution And Soil, Anthony F. Bertauski, John M. Swiader, David J. Wehner

Office of the Dean (CAFES) Scholarship

Because of the importance of such factors as appearance and vigor in turf management, genetic selection of Kentucky bluegrass (Poa pratensis L.) is often conducted at high levels of N application. This process can mask potential differences between genotypes in N efficiency, especially under low N levels. The case is also made that because soil is the medium in which plant selections ultimately must perform, cultivar screening for N efficiency in solution culture should relate to results in soil. This study was conducted to evaluate N-utilization efficiency (NUE – mg plant dry matter mg^-1 plant N) in six …

Conservation Compliance Credit For Winter Wheat Fall Biomass Production And Implications For Grain Yield, Gregory S. Mcmaster, Wallace Wilhelm

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

Producers participating in federal farm and conservation programs must reduce potential erodibility below certain thresholds on lands classified as highly erodible. The Natural Resource Conservation Service (NRCS) will credit producer s in Colorado for the quantity of green winter wheat (Triticum aestivum L.) biomass at the beginning of the winter period towards compliance in reducing erosion. Unfortunately, few data exist on fall winter wheat biomass production and fall production varies widely based on many site-specific factors at planting and during the fall, and can be expensive to document. To address these problems, a crop simulation model called SHOOTGRO …

Sp284-C-Planting Blackberries And Raspberries In Home Gardens, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Blackberries and raspberries (brambles) are a commonly planted small fruit in home gardens. They have vigorous growth, are seldom injured by spring frost and consistently produce high-quality fruit. The fruit is used for jams, jellies, pies and as a fresh fruit. Because of their vigorous growth, brambles should be planted in an area where they can be contained. They lend themselves as effective screens along property lines in landscapes. A reduction in the availability of wild berries make these fruits even more popular in home plantings. By choosing different types of brambles, you can harvest fresh fruit five to six …

Sp284-D-Planting Blueberries In Home Gardens, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Blueberries are a popular small-fruited plant in Tennessee. The fruit can be eaten fresh or used in jams, preserves, pies, with ice cream and in blueberry muffins and pancakes. Once established, plants are not difficult to maintain. Establishment, however, can be laborious. Plants can be easily grown in existing home landscapes and provide fruit while adding beauty to the landscape. Birds are usually the most troublesome pest after plants begin to fruit. After planting, the first good fruit yield will generally occur after three to five years. However, the length of time to fruiting will vary with the age of …

Predicting Developmental Morphology In Switchgrass And Big Bluestem, Rob B. Mitchell, Kenneth J. Moore, Lowell E. Moser, John O. Fritz, Daren D. Redfearn

Department of Agronomy and Horticulture: Faculty Publications

Switchgrass (Panicum virgatum L.) and big bluestem (Andropogon gerardii Vitman) are important warm-season grasses in livestock production systems in the central and eastern USA. The objectives of this study were to quantify the morphological development of ‘trailblazer’ switchgrass and 'Pawnee' big bluestem and to evaluate day of the year (DOY) and growing degree day (GDD) as predictors of switchgrass and big blnestem morphological stage. Pure stands of each species were sampled at weekly intervals in 1990 and 1991 at Mead, NE, and classified as to mean stage count (MSC) and mean stage weight (MSW). Prediction equations for MSC …

Asymbiotic In Vitro Seed Germination, Micropropagation And Scanning Electron Microscopy Of Several Temperate Terrestrial Orchids (Orchidaceae), Erika Szendrák

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Twenty-five different orchid species were successfully asymbiotically germinated and raised on a modified FAST medium (Fast 1976; Szendrák and R Eszéki, 1993). The development of geminating protocorms and young plantlets were recorded and compared among species. Spontaneous vegetative proliferation was also observed. Natural dispersed daylight and prevailing day-length were more favorable than l6-hour cool white fluorescent light for plantlet development. After two to three years of culture, the young plants were suitable for transfer ex vitro.

The effects of organic compounds most commonly used for orchid micropropagation (peptone, coconut water, casein+lactalbumin and glucose) and medium consistencies were investigated for …

Phosphorus And Nitrate Loss From Horticulture On The Swan Coastal Plain, Neil Clifton Lantzke

Agriculture reports

(En) The extent of nutrient loss from nine horticultural properties located on the sandy soils of the Swan Coastal Plain was examined. On three of the properties phosphorus (P) loss was measured by monitoring nutrient loads in shallow drains. On the other six properties networks of monitoring bores were installed and both P and nitrate nitrogen (NO3-N) concentrations were monitored. All of the properties except one were located on the low phosphate fixing Bassendean sands. The level of nutrient loss was depend l production areas. High to very high N03-N concentrations were found in the shallow groundwater beneath the production …
