Ecological And Genetic Variation Among Populations Of Boechera Caeruleamontana Sp. Nov. (Brassicaceae) From Blue Mountain And Dinosaur National Monumentin Eastern Utah And Western Colorado, Melissa Snyder Apr 2017

Ecological And Genetic Variation Among Populations Of Boechera Caeruleamontana Sp. Nov. (Brassicaceae) From Blue Mountain And Dinosaur National Monumentin Eastern Utah And Western Colorado, Melissa Snyder

Theses and Dissertations

Boechera is a large genus of flowering plants whose taxa are found primarily in North America. Boechera vivariensis (S.L. Welsh) W.A. Weber (the Park rockcress) is restricted to the Uintah Basin on Weber sandstone substrates in the vicinity of Dinosaur National Monument and Blue Mountain. The nomenclature of Park rockcress is significantly impacted by the discovery that the type collections of the taxon represent a rare, apomictic diploid resulting from the hybridization between B. thompsonii and an undescribed sexual diploid (to be called Boechera caeruleamontana sp. nov. Allphin and Windham). As a result, greater information is needed regarding how B. …


Population Genetics Of Greater Sage-Grouse In Strawberry Valley, Utah, Paula S. Dunken Jul 2014

Population Genetics Of Greater Sage-Grouse In Strawberry Valley, Utah, Paula S. Dunken

Theses and Dissertations

This study examined population genetics of greater sage-grouse (Centrocercus urophasianus) in Strawberry Valley, Utah located in the north-central part of the state. The Strawberry Valley population of sage-grouse experienced a severe population decline with estimates of abundance in 1998 less than 5% (~150 individuals) of similar estimates from the 1930s (>3,000 individuals). Given the population decline and reduced genetic diversity, recovery team partners translocated sage-grouse from four different populations into Strawberry Valley over 6 years (2003-2008). Translocations have been used as a strategy to increase both population size and genetic diversity in wildlife populations. We assessed whether genetic diversity …


Assessment Of Genetic Diversity Among Peruvian Amaranth (Amaranthus Caudatus L.) Germplasm Using Snp Markers, Felix Ruben Jimenez Rondan Jun 2011

Assessment Of Genetic Diversity Among Peruvian Amaranth (Amaranthus Caudatus L.) Germplasm Using Snp Markers, Felix Ruben Jimenez Rondan

Theses and Dissertations

Amaranth (Amaranthus caudatus L.) is an important pseudocereal in the Andes. The seed has excellent nutritional value (high in protein, essential amino acids, and minerals) and ample capacity for growth in diverse, harsh Andean subsistence-production conditions such as water deficiency, salt stress, and soil mineral nutrient deficiency. The objective of this study was to characterize and quantify the genetic diversity among a series of 178 mostly Peruvian amaranth genotypes using 96 biallelic single-nucleotide polymorphism (SNP) markers. A total of 96 co-dominant, biallelic markers were developed using KASPar™ assays on a 96.96 Fluidigm EP1 array system. The 178 amaranth genotypes …


Development And Use Of Microsatellite Markers For Genetic Diversity Analysis Of Canahua (Chenopodium Pallidicaule Aellen), Amalia Vargas Mar 2010

Development And Use Of Microsatellite Markers For Genetic Diversity Analysis Of Canahua (Chenopodium Pallidicaule Aellen), Amalia Vargas

Theses and Dissertations

Cañahua (Chenopodium pallidicaule Aellen) is a poorly studied, annual subsistence crop of the high Andes of South America. Its nutritionally value (high in protein and mineral content) and ability to thrive in harsh climates (drought, extreme elevations, etc.) make it an important regional food crop throughout the Andean region. The objectives of this study were to develop genetic markers and to quantify genetic diversity within cañahua. A set of 43 wild and cultivated cañahua genotypes and two related species (C. quinoa and C. petiolare) were evaluated for polymorphism using 192 microsatellite markers derived from random genomic …

Quinoa (Chenopodium quinoa Willd.) is a staple food crop for millions of impoverished rural inhabitants of Andean South America where it has been cultivated for millennia. Interest in quinoa, due largely to its superior nutritional characteristics, is fuelling a growing export market and has led to an increased focus on genetic research and the development of quinoa breeding programmes throughout South America. The success of these breeding programmes will rely heavily on the development of core germplasm collections and germplasm conservation. We report the development of a set of fluorescence-tagged microsatellite molecular markers that can be used to characterize genetic …

Assessment Of Chenopodium Quinoa Willd. Genetic Diversity In The Usda And Cip-Fao Collections Using Ssr?S And Snp?S, Shawn A. Christensen Nov 2005

Assessment Of Chenopodium Quinoa Willd. Genetic Diversity In The Usda And Cip-Fao Collections Using Ssr?S And Snp?S, Shawn A. Christensen

Theses and Dissertations

Quinoa (Chenopodium quinoa Willd.) is a staple grain for the indigenous people of the Andean region of South America with excellent nutritional qualities, including protein content. The objective of this study is to report on the development of fluorescence-tagged simple sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs) to (1) genetically characterize the inherent diversity of 152 accessions of C. quinoa; (2) determine to what degree the CIP-FAO collection represents the range of genetic diversity in quinoa; and (3) test four hypotheses regarding quinoa?s center of diversity, Highland and Lowland clustering patterns, origin of Lowland varieties, and the …
