Assessment of the microbiome associated with endangered orchids
(University of Missouri--Columbia, 2018)The Orchidaceae (orchid family) is perhaps the most speciose group of flowering plants with approximately 25,000 described species and many thousands of hybrids. While certain mycorrhizal fungi are required for orchids to ... -
Brassicales to Brassica : integrating phylogenomics and population genomics
(University of Missouri--Columbia, 2020)The Brassicales are an economically important order of flowering plants. Many crop species such as kale, broccoli, cabbage, cauliflower, canola oil, capers, and papaya, as well as the model plant organism, Arabidopsis ... -
C4 photosynthetic evolution : sub-types, diversity, and function within the grass tribe Paniceae
(University of Missouri--Columbia, 2017)Most plants convert sunlight into chemical energy using a process known as C[subscript 3] photosynthesis. However, some of the world's most successful plants instead use the C[subscript 4] photosynthetic pathway which ... -
The evolution of Brassica crops and wild relatives: phylogenetics, development and domestication
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The main goal of my dissertation is to understand the patterns and mechanisms underlying mustard (tribe Brassiceae, Brassicaceae) speciation in the ... -
Genome evolution in monocots
(University of Missouri--Columbia, 2011)Monocotyledonous plants are a well-circumscribed lineage comprising 25% of all angiosperm species, including many agriculturally and ecologically important species (e.g., grasses, palms, orchids, lilies, yams, pondweeds, ... -
Occurrence and implicatons of biological network evolution following polyploidy
(University of Missouri--Columbia, 2014)The mapping and comparison of biological networks allows for analysis to understand forces of evolution. Here, we synthesize information about polyploidy, or whole genome duplication, and its effects on network rewiring. ... -
Phylogenetic and phylogenomic studies of wild onions (Allium, Amaryllidaceae) at three taxonomic scales
(University of Missouri--Columbia, 2011)I used standard molecular phylogenetic and emerging phylogenomic methods to address questions about the evolutionary relationships among populations, species and subgeneric clades of the genus Allium. To test the hypothesis ... -
Phylogenomics of ancient whole genome duplications in the Brassicales
(University of Missouri--Columbia, 2011)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Ancient whole genome duplications (WGDs), which multiply copies of the entire genome within an organism, are ubiquitous throughout the evolutionary ... -
Phylogenomics of orchids and their mycorrhizal fungi : trees, diversity, and the pursuit of symbiosis
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Phylogenetic trees show us how organisms are related and provide frameworks for studying and testing evolutionary hypotheses. To better understand the ... -
The power of synteny : deep evolutionary insights from comparative genomics
(University of Missouri--Columbia, 2021)Synteny, or the order of genes in a given genome, is an emergent property of individuals and species that has only, with the implementation of next gen-sequencing, become available for evolutionary consideration. In this ...
