Adaptation and hybridization in Helicoverpa crop pests
… in general, specifically considering the use of whole-genome resequencing data. In Chapter 2, I apply these principles to a study of native H. zea in North America. I reveal genomic signatures of selection at two cytochrome P50 genes associated with pesticide resistance: one rose quickly in …

Dissecting the evolutionary forces shaping sex chromosome evolution in papaya
… of the X chromosome and 4 times the papaya genome-wide average. Furthermore, a chloroplast genome fragment containing the rsp15 gene has been amplified 23 times in the HSY, evidence of retrotransposon-mediated duplication. The accumulated chloroplast DNA is evidence of the slow degeneration …

GENETIC DISSECTION OF MATURITY DATE IN PEACH AND APRICOT REVEAL A ROLE FOR CONSERVED GENE NETWORKS
… peach became a model crop, a relatively small genome (about 256 Mb), diploidy (2n = 2x = 16) and low heterozygosity. Conversely apricot shows high levels of heterozygosity and consistent structural variations, limiting a direct knowledge transfer from peach. Maturity Date (MD) is a complex …

Evolution's footsteps : reconstructing in vitro and in vivo evolutionary trajectories via massively parallel sequencing and profiling
… development of technologies for cost-effective whole-genome resequencing offers the opportunity to comprehensively study evolution in action. Here, I present a combined experimental and computational strategy to detect and study recurrent genetic aberrations accompanying adaptive evolution in …

Genomics and ecology of rapid adaptation: the expansion and evolution of the invasive common myna (<i>Acridotheres tristis</i>) and common starling (<i>Sturnus vulgaris</i>) in New Zealand
… invasions in New Zealand. Lastly, I utilised whole-genome resequencing data from 82 myna individuals from four native and seven invasive populations, representing two independent introduction pathways, to identify parallel signatures of selection associated with invasion. A strongly selected …

Evolution, epistasis, and the genotype-to-phenotype problem in Myxococcus xanthus.
… used to describe its phenotype. Furthermore, the genome of M. xanthus is large, encoding a predicted 7,314 genes, many of which have been linked to aspects of its multicellular phenotype.</p> <p>This work presented here addresses the genotype-to-phenotype (G2P) problem as it relates to the …

Rapid diversification and wing colour pattern evolution in tropical butterflies
… drivers of rapid diversification through whole genome resequencing of most (sub)species covering a wide geographic range. Chapter 3 focuses on colour pattern evolution in one species per genus, through genome-wide association studies in several convergent phenotype switches. Chapter 4 …

Genomic Reconstruction of the Domestication History of Sinningia speciosa (Lodd.) Hiern, and the Development of a Novel Genotyping Approach
… other features such as a small, low-complexity genome, ease of cultivation, and rapid generation time, makes this species an attractive model for the study of genomic variation under domestication. Basic research on non-model organisms with low economic importance is uncommon but necessary to …

Genomic insights into the evolution of the parasitoid Microctonus aethiopoides
… M. aethiopoides in New Zealand by analysing whole-genome resequencing data from 43 individuals representing historic (Ireland) and contemporary populations. The study reveals two distinct genetic clusters, most likely reflecting the genetic ancestry of introduced populations rather than …

GENETIC DISSECTION OF PINE1 CONTROLLED STEM ELONGATION AND NEW INSIGHTS INTO LONG DAY FLOWERING IN ORYZA SATIVA
… is a rapid gene identification method based on whole-genome resequencing of pooled DNA from F2 segregating populations. In this study, it was applied to one F2 population derived from an early-flowering 5 line and to two additional populations derived from late-flowering lines. MutMap revealed …

Introgression, Population Structure, and Systematics of the Sphagnum capillifolium complex
… patterns of phylogenetic discordance across the genome in the Sphagnum capillifolium complex using whole genome resequencing data. The species tree phylogeny was generally well supported but phylogenetic discordance among genomic regions was prevalent, especially at nodes in the backbone. …

Characterization of arbuscular mycorrhial fungi on Glycine max and its influence on plant disease severity
… with mycorrhizal colonization in soybean. A genome-wide association analysis was deployed using a diverse panel of 350 exotic soybean accessions inoculated with Rhizophagus intraradices. Roots of all accessions were microscopically evaluated for colonization by R. intraradices using a …

Advancements in Isotopic Geolocation Tools for Insect Migration Research
… Despite these differences in migration distance, genome-wide analysis revealed a lack of adaptive variation between short- and long-distance migrants. Instead, variation in migration distance in painted lady butterflies is likely the result of a plastic response to environmental conditions. …
