Abstract:

Genome rearrangements represent a common mode of molecular evolution. A framework of possible models to study genome rearrangements is to represent genomes as signed permutations of genes and compute their distances based on the minimum number of certain operations (evolutionary events) needed to transform one permutation into another. Under these models, the shorter the distance, the closer the genomes are. In this talk, I will at first give an introduction of genome rearrangements, then report some new results in the field we got recently.
