Evidence for quasi-palindrome to palindrome conversion via template switching during evolution of S. cerevisiae. (A) A phylogenetic tree of seven Saccharomyces genomes. (B) Three perfect palindromes appear in S288c three coding regions. Different perfect palindromes appear at the same loci in three additional genomes. Each locus is shown in a column and different colors show different palindrome forms. Loci that are in a quasi-palindromic state are shown in gray. Cases in which the loci could not be identified are shown in black. Positions identical to S288c are shown with a dot and the spacer between arms is represented with a tilde sign. (C) Ninety-two S288c loci that appear in two additional genomes.
