1. Myofibroblasts and polyploid cells in the conjunctival surface after allogeneic hematopoietic stem cell transplantation
Abstract : Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment modality for hematological malignancies, such as leukemia and lymphoma. However, a major complication of the procedure is that the immune effector cells in the graft may become activated towards the host´s healthy tissues, resulting in a condition called Graft-versus-Host Disease (GvHD).

3. 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

4. Systematics and polyploid evolution in Potentilleae (Rosaceae)
Abstract : This thesis comprises studies of the phylogenetic relationships in the flowering plant clade Potentilleae in Rosaceae. The relationships were elucidated by using DNA sequence data from the nuclear genome as well as from the plastid genome. In particular, the focus of the studies was the investigation of allopolyploidy, i.e. READ MORE

5. Systematics of Woodsia : Ferns, bioinformatics and more
Abstract : 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. READ MORE
