2. Evolution of Flowering Time in the Tetraploid Capsella bursa-pastoris (Brassicaceae)
Abstract : Although polyploidy is believed to be a major source of evolutionary novelty, few studies have examined the genetic basis of phenotypic variation in wild polyploids. In this thesis I have studied the genetic basis of flowering time variation in the wild tetraploid crucifer Capsella bursa-pastoris, as well as the evolutionary history of this species. READ MORE

3. Genome evolution and adaptation of a successful allopolyploid, Capsella bursa-pastoris
Abstract : The term allopolyploid refers to an organism that originated through hybridization and increased its ploidy level by retaining the unreduced genomes of its parents. Both hybridization and polyploidy usually have negative consequences for the organism. READ MORE

4. Genomic and phenotypic consequences of allopolyploidization in Capsella
Abstract : Allopolyploidization, the combination of whole-genome duplication (WGD) and interspecific hybridization, is a frequent and influential event in plant evolution. Allopolyploidization potentially affects both adaptation and diversification, yet the understanding of the consequences of allopolyploidy has been obscured by several issues. READ MORE

5. Studies on Natural Variation and Evolution of Photoperiodism in Plants
Abstract : Photoperiodism refers to the organism’s ability to detect and respond to seasonal changes in the daily duration of light and dark and thus constitutes one of the most significant and complex examples of the interaction between the organism and its environment. This thesis attempts to describe the prevalence of variation in a photoperiodic response, its adaptive value, and its putative genetic basis in a common cruciferous weed, Capsella bursa-pastoris (Brassicaceae).
