摘要: Evolutionary trees of species can be reconstructed by pair-wise comparison their entire genomes. Such a quantified determining the number events that change order genes in genome. Earlier Erdem and Tillier formulated pairwise genomes as problem planning rearrangement transform one genome to other. We reformulate this extend its applicability with multiple copies unequal gene content, illustrate effectiveness on three real datasets: mitochondrial Metazoa, chloroplast Campanulaceae, various land plants green algae.
