Using Multi-Omics Approaches To Study Flowering Time And Fruit Development In Perennial Fruit Species, Jiali Yu
Doctoral Dissertations
Perennial fruiting plants coordinate their reproductive activities with seasonal changes in the temperate climates, with a pattern of bud set, dormancy establishment, fulfillment of chilling, flowering, fruit set, and fruit ripening. These processes have been optimized for the production of orchard plants that reliably produce quality fruit for human consumption. The understanding of molecular controls of dormancy in fruit trees has grown rapidly in the past decade, however, the complex mechanisms remain largely unknown. This dissertation presents my findings on genetic and epigenetic changes in Prunus species from dormancy to flowering using transcriptomics and epigenomics approaches. First, I compared the …

Impacts Of Genome And Nuclear Architecture On Molecular Evolution In Eukaryotes, Xyrus Maurer-Alcalá
Doctoral Dissertations
The traditional view of genomes suggests that they are static entities changing slowly in sequence and structure through time (e.g. evolving over geological time-scales). This outdated view has been challenged as our understanding of the dynamic nature of genomes has increased. Changes in DNA content (i.e. polyploidy) are common to specific life-cycle stages in a variety of eukaryotes, as are changes in genome content itself. These dramatic genomic changes include chromosomal deletions (i.e. paternal chromosome deletion in insects; Goday and Esteban 2001; Ross, et al. 2010), developmentally regulated genome rearrangements (e.g. the V(D)J system in adaptive immunity in mammals; Schatz …
