Mixed infections of maize dwarf mosaic virus and cucumber mosaic virus in maize
… found to be doubly infected with maize dwarf mosaic (MDMV) and cucumber mosaic virus (CMV). A mixed infection of these two viruses could be maintained in maize plants grown under laboratory conditions. The possibility of synergism or of an interference mechanism between MDMV and CMV in dual …

Tamarillo mosaic potyvirus: characterization and resistance
… fruit is severely decreased by tamarillo mosaic potyvirus (TaMV) which detrimentally affects fruit colour resulting in the fruit being unacceptable on the international marketplace. Virus incidence was surveyed in four tamarillo growing regions. Viruses were detected by indicator plant …

The characterisation of Ornithogalum mosaic virus
Ornithogalum mosaic virus (OMV) is the most serious pathogen of commercially grown Ornithogalum and Lachenalia species in South Africa. Although omithogalum mosaic disease was first reported as early as 1940, attempts to purify or characterise the virus(es) were not successful. The extremely …

Crossing Number Bounds of Mosaic Knot Diagrams
… we tabulate some previously undocumented link mosaic diagrams. Next we prove an upper and lower bound on crossing number of certain mosaic diagrams of knots in terms of winding number for knot diagrams that make only counterclockwise turns. Next we begin drawing mosaic diagrams that have a more …

Cairn Stones: A Mosaic Memoir and Manual
… each other, but are not meant to fit tidily—the mosaic nature is part of the point. Partly, of course, these essays are my own efforts to grapple sense and meaning into the very bland and bleak way the world can often be. But, moreover, it is my hope that they will be read as posts and markers to …

Firestorms in a mesic savanna-forest mosaic
Forests and savannas in a savanna-forest mosaic are maintained by positive feedback loops with fires, promoting fires in savannas and excluding fires in forests. Occasional extreme fires do however burn into forest edges and cause extensive mortality. So, while our understanding of bistability in …

Soybean mosaic virus: strains, ultrastructure and movement
Two Virginia isolates of soybean mosaic virus (SHV), VA and OCM, were classified as G1 and G3 strains, respectively, according to a soybean differential cultivar system. G1/VA and G3/OCM differed in the symptom severity induced on soybean (Glycine max [L.]Merr.) plants and by the production by …

Soybean mosaic virus-soybean interactions: molecular, biochemical, physiological, and immunological analysis of resistance responses of soybean to soybean mosaic virus
Strain-specific resistance conditioned by a single dominant gene in soybean cv. York inoculated with SMV-G1, revealed no symptoms and no detectable viral replication (R). Unlike the hypersensitive response (HR), the R response did not result in localized virus and induction of a series of defense …

A Geographic Mosaic of Speciation in Eurosta solidaginis
… result in what may be called a “Geographic Mosaic of Speciation”. A Geographic Mosaic of Speciation provides an opportunity to study the process of speciation in various degrees of completion. Eurosta solidaginis (Diptera: Tephritidae) is a fly that induces galls on tall goldenrod (Solidago …

The writing classroom as a mosaic: Three perspectives
"A qualitative study looked at ways in which teachers and students engaged in and reflected on the process approach to writing in a traditional high school setting in the Midwest. The school was affiliated with a major research university and its population was exclusively ""gifted"" students, here …

Molecular Studies on Soybean Mosaic Virus-Soybean Interations
In the U.S., soybean mosaic virus (SMV) is classified into seven strain groups, designated G1 to G7, based on their different responses on resistant soybean [Glycine max (L.) Merr.] cultivars. These responses are: symptomless or resistant (R), necrotic (N), and mosaic or susceptible (S). The …

Controlling Tobacco Mosaic Virus in Tobacco through Resistance
Tobacco mosaic virus (TMV) infects all classes of tobacco (Nicotiana tabacum L.) and causes losses worldwide. The N gene is the most effective means of controlling TMV; however, this gene is associated with reduced yield and quality in flue-cured tobacco. The mode of inheritance of TMV resistance …

Cloning and characterization of the 3' terminal regions of RNA from select strains of maize dwarf mosaic virus and sugarcane mosaic virus
… from the 3$\sp\prime$ terminus of maize dwarf mosaic virus, strain A (MDMV-A), maize dwarf mosaic virus, strain B (MDMV-B), maize dwarf mosaic virus, strain KS1 (MDMV-KS1), maize dwarf mosaic virus, strain O (MDMV-O), and sugarcane mosaic virus strain H have been cloned as a first step in the …

The Racial Mosaic: Race, Cultural Pluralism, and Canadian Multiculturalism
This dissertation examines the intellectual origins of the Canadian federal government’s official policy of multiculturalism. The first half employs the methodology of historical biography and examines the life and thought of three Canadian public intellectuals: T. Watson Kirkconnell, Robert …

Genetic resistance to and diversity of soybean mosaic virus
… of their resistant reactions to soybean mosaic virus (SMV) strain G1. Each of the cultivars was crossed with a susceptible cultivar Williams to determine the number of genes for resistance. The four cultivars were also crossed with lines with known genes for resistance to SMV to test for …

Effects of Cucumber Mosaic Virus on Plant-Pollinator Relationships
… arena experiments in the Carr lab, cucumber mosaic virus (CMV) was shown to cause plants to emit volatile chemicals that attract bumblebees (Bombus terrestris). Bumblebees are important tomato pollinators but do not transmit CMV. For wild plants under natural conditions, helping host …
