Epigenetic History Of An Arabidopsis Trans-Silencer Locus And A Test For Relay Of Trans-Silencing Activity, Huaxia Qin, Albrecht G. Von Arnim Dec 2002

Epigenetic History Of An Arabidopsis Trans-Silencer Locus And A Test For Relay Of Trans-Silencing Activity, Huaxia Qin, Albrecht G. Von Arnim

Plant Sciences Publications and Other Works

Background

Meiotically heritable epimutations affecting transgene expression are not well understood, even and in particular in the plant model species, Arabidopsis thaliana. The Arabidopsis trans-silencer locus, C73, which encodes a fusion protein between the repressor of photomorphogenesis, COP1, and green fluorescent protein (GFP-COP1), heritably modifies the expression pattern and cop1-like cosuppression phenotypes of multiple GFP-COP1 target loci by transcriptional gene silencing.

Results

Here we describe three additional features of trans-silencing by the C73 locus. First, the silencing phenotype of C73 and of similar complex loci was acquired epigenetically over the course of no more than two plant …

A Simple Test To Evaluate The Calibration Stability And Accuracy Of Infrared Thermocouple Sensors, Derek R. Pinnock, Bruce Bugbee

Techniques and Instruments

Accurately measuring surface temperature is not difficult when the surface, the sensor, and air temperatures are similar, but it is challenging when the surface temperature is significantly different than air and sensor temperatures.

We tested three Infrared Thermocouple sensors (IRT’s) that had been used for two years in a greenhouse environment. The importance of the correction for sensor body temperature was also examined.


Effects Of Beauveria Bassiana Mycelia And Metabolites Incorporated Into Synthetic Diet And Fed To Larval Helicoverpa Zea; And Detection Of Endophytic Beauveria Bassiana In Tomato Plants Using Pcr And Its Primers, Brian Michael Leckie Dec 2002

Effects Of Beauveria Bassiana Mycelia And Metabolites Incorporated Into Synthetic Diet And Fed To Larval Helicoverpa Zea; And Detection Of Endophytic Beauveria Bassiana In Tomato Plants Using Pcr And Its Primers, Brian Michael Leckie

Masters Theses

Beauveria bassiana (Balsamo) Vuillemin is an entomopathogenic deuteromycete that has been used in biological control of insect pests. Recent studies have revealed that B. bassiana is an endophyte of corn plants, and that plants colonized by the fungus had a reduction in tunneling from the European corn borer, Ostrinia nubilalis (Hubner) (Lepidoptera: Crambidae). In addition to corn, B. bassiana has been observed to grow endophytically in potato plants. Beauveria bassiana may also have the ability to colonize closely related plants and potentially reduce insect feeding on them.

This study has three objectives. The first was to evaluate the effect of …

Soils Of Mississippi County, Arkansas, J. M. Mckimmey, B. Dixon, H. D. Scott, C. M. Scarlat

Research Reports and Research Bulletins

Along with air and water, soil contributes essential processes to the natural order of global cycles. With the exception of edibles from the sea, virtually everything we, and most other land-based animals, eat is derived from soil. Soil is a storage medium of essential minerals and nutrients for fulfilling our agricultural and nutritional needs. Humans work the soil to provide the basics of food, clothing, and shelter. We also use the soil as a medium to store and discard our waste. Virtually everything we do is in some way connected to soil

Detection Of Phosphorus And Nitrogen Deficiencies In Corn Using Spectral Radiance Measurements, S.L. Osbourne, James S. Schepers, D. Francis, Michael R. Schlemmer Nov 2002

Detection Of Phosphorus And Nitrogen Deficiencies In Corn Using Spectral Radiance Measurements, S.L. Osbourne, James S. Schepers, D. Francis, Michael R. Schlemmer

Department of Agronomy and Horticulture: Faculty Publications

Applications of remote sensing in crop production are becoming increasingly popular due in part to an increased concern with pollution of surface and ground waters due to over-fertilization of agricultural lands and the need to compensate for spatial variability in a field. Past research in this area has focused primarily on N stress in crops. Other stresses and the interactions have not been fully evaluated. A field experiment was conducted to determine wavelengths and/or combinations of wavelengths that are indicative of P and N deficiency and also the interaction between these in corn (Zea mays L.). The field experiment …

Department of Agronomy and Horticulture: Faculty Publications

Rainfed and irrigated systems in which corn is grown either in rotation with soybean or as a continuous monocrop are the predominant cropping systems in North America. About 30 million ha of corn are harvested annually for grain in the USA, of which eleven states in the Corn Belt produce more than 210 million tons or 35% of the global corn supply (Dobermann and Cassman, 2002). During the past 35 years, average corn yields have increased linearly at a rate of 1.7 bu/acre per year (109 kg ha-1 per year, Fig. 1). Average corn yields now approach 140 bu/acre …

An Evolutionary Perspective Of Pierce’S Disease Of Grapevine, Citrus Variegated Chlorosis, And Mulberry Leaf Scorch Diseases, Jianchi Chen, John S. Hartung, Chung-Jan Chang, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

Xylella fastidiosa causes diseases on a growing list of economically important plants. An understanding of how xylellae diseases originated and evolved is important for disease prevention and management. In this study, we evaluated the phylogenetic relationships of X. fastidiosa strains from citrus, grapevine, and mulberry through the analyses of random amplified polymorphic DNAs (RAPDs) and conserved 16S rDNA genes. RAPD analysis emphasized the vigorous genome-wide divergence of X. fastidiosa and detected three clonal groups of strains that cause Pierce’s disease (PD) of grapevine, citrus variegated chlorosis (CVC), and mulberry leaf scorch (MLS). Analysis of 16S rDNA sequences also identified the …
