Air Quality And Agriculture, Rhonda Miller

All Current Publications

There are many human factors that contribute to poor air quality, and agriculture is no exception. Best management practices such as the immediate incorporation of manure, nutrient conservation,reduced fertilizer use, reduced tillage, keeping silage covered, covers on manure storage structures,and alternatives to burning can help minimize emissions of air pollutants. Although livestock production is a significant contributor of greenhouse gases, long-term cropping systems can sequester carbon which reduces greenhouse gas emissions.

Department of Agricultural Economics: Faculty Publications

We assess the literature on public and private quality standards and their impact in food markets, international trade, and global supply chains. We focus on their effects on welfare, trade, industrial organization, and labor markets and with special attention to the North-South context. We also attempt to better characterize when these measures constitute protectionism, a complicate task. We look at studies investigating public and private standards and across various quantitative approaches and countries. These standards have complex effects. The evidence is mixed regarding standards as catalyst for or impediment against trade and development, reflecting the complexity of these effects and …

Search For Host Factors Involved In Attachment Of Agrobacterium Tumefaciens To Plants, Anna Petrovicheva

Dissertations, Theses, and Capstone Projects

Agrobacterium tumefaciens is able to infect a diverse array of plants and causes crown gall disease. Typically these bacteria attach to plant roots and transform the plant cells to induce tumors. The mechanism of this attachment in the infection process is not yet fully understood. Using wild type Arabidopsis thaliana, Columbia-0, and several Arabidopsis mutant lines as a binding target, we screened for A. thaliana mutants with altered adhesion.

The A. thaliana mutant lines were selected in The Arabidopsis Information Resource (TAIR) according to possible location of the resulting protein and similarity to known transformation mutants. Of these mutants …

Systematics And Biogeography Of Orthaea Kloztsch (Ericaceae: Vaccinieae), Nelson Salinas

Dissertations, Theses, and Capstone Projects

In the first chapter a study of the distribution patterns of the neotropical Vaccinieae (Ericaceae) is presented. Five areas of endemism were recovered: Central America, northern Chocó, southern Chocó, eastern Ecuador, and Yungas. Divergence times estimations indicate that the Andean clade of Vaccinieae migrated to South America during the Late Oligocene or Early Miocene (28.9-17.84 MA), and most of the subsequent diversification took place during the Tertiary. The Yungas was the first Andean area to be colonized, and several dispersals towards the north expanded their distribution range. Both areas of endemism and dispersal events were influenced by geological processes, such …

Single Nucleotide Polymorphism Discovery Through Illumina-Based Transcriptome Sequencing And Mapping In Lentil, Hülya Yilmaz Temel, Deni̇z Göl, Hi̇lal Betül Kaya Akkale, Abdullah Kahri̇man, Muhammed Bahatti̇n Tanyolaç

Turkish Journal of Agriculture and Forestry

Lentil, which belongs to the family Leguminosae (Fabaceae), is a diploid (2n = 2x = 14 chromosomes) self-pollinating crop with a genome size of 4063 Mbp. Because of its nutritional importance and role in the fixation of nitrogen from the atmosphere, lentil is a widely used crop species in molecular genetic studies. By using DNA markers, to date, a limited number of polymorphic bands have been generated. Therefore, it is necessary to develop additional markers to saturate the genome at high density. Single nucleotide polymorphism (SNP) markers are promising for this purpose because of their abundance, stability, and heredity; they …

The Use Of Oral History And Narrative Research In Broadening The Historical Foundation Of The Agricultural Communication Field, Natalie L Federer

Open Access Dissertations

The historical foundation of the agricultural communication community (consisting of both academics and the profession) is shallow and void of humanistic perspective, and there is a minimal amount of historical content that focuses on academic and professional history. The need to explore and interpret historical dimensions of this field is vital to further development of the discipline as an academic and professional field. Oral history was utilized to capture and preserve the interview content from a small sample of agricultural communication and Extension professionals and faculty while narrative research, interpretative theory, and constructivism were utilized to further understand and interpret …
