Recent analyses of plant genomic data have found extensive evidence of ancient whole genome duplication (or polyploidy) events, but there are many unresolved questions regarding the number and timing of such events in plant evolutionary history. We describe the first exact and efficient algorithm for the Episode Clustering problem, which, given a collection of rooted gene trees and a rooted species tree, seeks the minimum number of locations on the species tree of gene duplication events… CONTINUE READING
