A Synopsis Of The Ferns And Fern Allies Of Nebraska, With Maps Of Their Distribution, Steven B. Rolfsmeier, Robert B. Kaul, David M. Sutherland

School of Biological Sciences: Faculty Publications

An annotated list and county-by-county distribution maps are presented for the 32 species of ferns and fern allies native to Nebraska, based upon field and herbarium studies and critical evaluation of the literature. Native to the state are Isoetes melanopoda, Selaginella rupestris, five species of Equisetum, and 25 species in 18 genera of ferns. Three native species are here verified for the first time, based upon recent collections: Matteuccia struthiopteris var. pensylvanica, Ophioglossum engelmannii, and Pellaeaglabella ssp. glabella. Isoetes melanopoda was rediscovered in 2000, the first record since 1941. Rejected are published reports …

Molecular Phylogenetic Studies In Rosaceae, Christopher S. Campbell

University of Maine Office of Research Administration: Grant Reports

This project will investigate the evolutionary relationships within the large and important rose family. This group of plants contains numerous commercially valuable fruits (apples, pears, strawberries, cherries, peaches, plums, blackberries, and raspberries) and many horticulturally significant plants (roses, cotoneaster, lady's mantle, bridle-wreath, flowering quince, fire-thorn, cinqfoil, and others). Despite the large and important role that these plants play in our daily lives and scientific interest, we do not have a clear view of the evolutionary relationships of members of the family. A primary reason for this situation is that insufficient evidence has been accumulated to adequately address the problem. A …

Specialty Tomato Cultivar Trial For Indiana, 2001, Elizabeth Maynard, Dale Rhoads, Sandy Rhoads

Purdue Fruit and Vegetable Research Reports

Colorful tomato salads are a seasonal menu item for some restaurants. The many colors of tomato fruit available include orange, green, white, yellow and, of course, red. Producers growing for this market have a choice of several cultivars of each color, and sometimes several fruit shapes within a color. Many of the cultivars are open-pollinated but some hybrids are available. Prior experience at Rhoads Farm and elsewhere has shown that many open-pollinated cultivars yield poorly under Indiana conditions, making them an unprofitable crop. The trials presented in this report were established to evaluate tomato cultivars for the restaurant salad market.

Fresh Market Tomato Pruning Trial For Northern Indiana, 2001, Elizabeth Maynard

Purdue Fruit and Vegetable Research Reports

Pruning tomatoes is known to increase average fruit size and decrease total yield. Effects on marketable yield and early yield vary among cultivars and with the degree of pruning. This trial was conducted to evaluate a range of pruning treatments on two cultivars grown in the Midwest: Mountain Spring and Florida 91. Florida 91 has a larger vine and is later-maturing than Mountain Spring. The trial was conducted at the Pinney-Purdue Agricultural Center in Wanatah, Indiana.

Fresh Market Tomato Cultivar And Pruning Evaluation For Northern Indiana, 2000, Elizabeth Maynard

Purdue Fruit and Vegetable Research Reports

Fresh market tomatoes were evaluated at the Pinney-Purdue Agricultural Center in Wanatah, Indiana. Nine beefsteak types and one roma type were evaluated in a replicated trial. Plants were grown with and without pruning to evaluate pruning effects on yield and fruit quality. The main benefit of pruning is larger fruit size. For some cultivars, there might be an increase in total yield at the first harvest with pruning, as was seen to a small extent for Mt. Spring. Pruning also reduced the incidence of catfacing, especially for early cultivars. The main drawback of pruning is reduced yield. For pruning to …

Septum Formation In Aspergillus Nidulans, Steven D. Harris

Department of Plant Pathology: Faculty Publications

Filamentous fungi form multicellular hyphae that are partitioned by septa. In A. nidulans, septum formation requires the assembly of a septal band following the completion of mitosis. Recent observations show that this band is a dynamic structure composed of actin, a septin and a formin. In addition, assembly is dependent upon a conserved protein kinase cascade that regulates mitotic exit and septation in yeast. Hyphal differentiation may reflect the regulation of this cascade by cyclin-dependent kinase activity. In this review, the dynamics and regulation underlying the assembly of the septal band are discussed.

Efficacy Of Sucker Control Method And Effect Of Topping Height On Axillary Bud Growth In Dark Fire-Cured Tobacco, Leslie Thompson

Masters Theses & Specialist Projects

The removal of terminal buds (topping) and sucker control are two practices that have an impact on yield and quality of dark tobacco (Nicotiana tabacum L.). Topping breaks apical dominance and encourages the growth of axillary buds (suckers). Following topping, growth regulator chemicals known as suckercides are commonly used to prevent axillary bud growth. Research has demonstrated that topping time, height, and sucker control method influence the quality and yield of the final product. Delaying topping past a critical developmental stage has been shown to reduce leaf yield. Topping height varies among geographical regions with most dark tobacco producers topping …

Efficacy Of Soybean Herbicides On Annual Morninglory, Dawn Oveson

Masters Theses & Specialist Projects

Field experiments were established in 2000 and 2001 at the Agricultural Research and Education Complex in Bowling Green, Kentucky to evaluate herbicide efficacy on annual morningglory (Ipomoea spp.) species and other weeds. A randomized complete block design was utilized in each study with each treatment being replicated three times. Plots consisted of four 76 cm rows, 9.1 m in length. The two center rows of each plot were treated, with the outside rows of each plot serving as a weedy check. Crop response, weed control, and grain yield data were collected. Four different experiments were conducted. Two experiments utilized treatments …

Oestrus Ovis In Sheep: Relative Third-Instar Populations, Risks Of Infection And Parasitic Control, Guillaume Tabouret, Philippe Jacquiet, Philip Scholl, Philippe Dorchies

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

Oestrus ovis (L.) (Diptera: Oestridae), the nasal bot fly, has a relatively short free-living life cycle outside of the host, and therefore it is necessary to know when the parasitic period occurs in order to prevent the clinical signs and economic losses caused by this parasite. The length of this parasitic portion of the life cycle is quite variable: a few weeks to several months depending on the season and climatic conditions. Surveys of Oestrus ovis larval populations in sheep show different results on the number of generations according to the local climate. Mean monthly larval profiles of L1 and …

The Ns5a Protein Of Bovine Viral Diarrhoea Virus Interacts With The Α Subunit Of Translation Elongation Factor-1, Craig M. Johnson, Daniel R. Perez, Roy C. French, William C. Merrick, Ruben O. Donis

Department of Plant Pathology: Faculty Publications

A cellular protein that interacts with the NS5A polypeptide of bovine viral diarrhoea virus (BVDV) was identified in a yeast two-hybrid screen. The NS5A interactor was identified as the a subunit of bovine translation elongation factor 1A (eEF1A). Cell-free binding studies were performed with chimeric NS5A fused to glutathione S-transferase (GST–NS5A) expressed in bacteria. GST–NS5A bound specifically to both in vitro-translated and mammalian cell-expressed eEF1A. Moreover, purified eEF1A bound specifically to GST–NS5A attached to a solid phase. Conservation of this interaction was then analysed using a set of NS5A proteins derived from divergent BVDV strains encompassing known biotypes and genotypes. …
