Sammanfattning : Two whole genome duplications (2R) occurred early in vertebrate evolution. By using combined information from phylogenetic analyses and chromosomal location of genes, this thesis delineates the evolutionary history of two receptor-ligand systems that expanded by these large scale events.

Sammanfattning : The duplication of genes followed by selection is perhaps the most prominent way in which molecular biological systems gain multiplicity, diversity and functional complexity in evolution. Whole genome duplications (WGDs) therefore have the potential of generating an extraordinary amount of evolutionary innovation. LÄS MER
Sammanfattning : Protein-coding genes evolve together with their genome and acquire changes, some of which affect the length of their protein products. This explains why equivalent proteins from different species can exhibit length differences. LÄS MER
4. Evolutionary Analysis of the Insulin-Relaxin Gene Family from the Perspective of Gene and Genome Duplication Events
Sammanfattning : Paralogs arise by duplications and belong to families. Ten paralogs (insulin; IGF-1 and -2; INSL3-6 and 3-relaxins) constitute the human insulin-relaxin family. The aim of this study was to outline the duplications that gave rise to the vertebrate insulin-relaxin genes and the chromosomal regions in which they reside. LÄS MER
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
