21. Organization of centromere associated DNA in Chironomus pallidivittatus
Sammanfattning : Centromeres have not yet been functionally defined in higher eu- karyotes, largely due to the huge amounts of repeated DNA in these regions of most species and difficulties of delimiting centromeric from pericentric regions. Also the latter have large quantities of mostly noncoding DNA, expressed cytologically as pericentric heterochromatin. LÄS MER
22. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution
Sammanfattning : Malaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. LÄS MER
23. Dagens Gennyheter : Hur massmedier berättar om genetik och genteknik
Sammanfattning : During the 1990’s gene technology got a break-through – both as a science and in people’s consciousness. Media reported frequently about scientific breakthroughs. LÄS MER
24. Regulation of Drosophila Jun by phosphorylation and the ubiquitin system during eye development
Sammanfattning : The goal of these studies has been to elucidate the biological relevance of post-translational modifications in the context of a living organism. The model system used is photoreceptor differentiation during development of the compound eye in the fruit fly Drosophila melanogaster. LÄS MER
25. Genome Divergence in Progress - a population genetic analysis of the allopolyploid Arabidopsis suecica and its maternal parent A. thaliana
Sammanfattning : The evolutionary history of the allotetraploid Arabidopsis suecica and its maternal parent Arabidopsis thaliana is analyzed in the thesis in terms of genetic variation in the natural populations of the two species. The earliest phase of the speciation event in which the genomes of A. thaliana and A. LÄS MER
