1. Polyploid Phylogenetics in Plants: Insights on non-model organisms in Fabaceae and Malvaceae
Sammanfattning : Genome duplication is a common phenomenon in angiosperms and advances in sequencing technologies and bioinformatics is now revealing its prevalence and significance. In a polyploidization event all genes in a genome are doubled. LÄS MER
2. Plant polyploidy and interactions with insect herbivores
Sammanfattning : Polyploidization has been suggested to be a common mechanism for plant speciation. Polyploidy is associated with changes in plant traits and altered habitat preference. LÄS MER
3. Systematics of Woodsia : Ferns, bioinformatics and more
Sammanfattning : Ferns are one of the three main clades of vascular plants. They have few easily studied morphological characters, reflected in a historically unstable classification. The fern genus Woodsia is known to have a complex evolutionary history including numerous polyploid taxa and hybrids. LÄS MER
4. Systematics of polyploid Dactylorhiza (Orchidaceae) - genetic diversity, phylogeography and evolution
Sammanfattning : This thesis examines genetic variation in allotetraploids of the Dactylorhiza incarnata/maculata polyploid complex in different parts of Europe. The molecular markers used were AFLPs, allozymes, ITS, nuclear microsatellites and plastid DNA markers. LÄS MER
5. Cis-regulatory variation and divergence in Capsella
Sammanfattning : Cis-regulatory changes in e.g. promoters or enhancers that affect the expression of a linked focal gene have long been thought to be important for adaptation. In this thesis, I investigate the selective importance and genomic correlates of cis-regulatory variation and divergence in the genus Capsella, using massively parallel sequencing data. LÄS MER
