Evidence for the evolution of multiple genomes in arbuscular mycorrhizal fungi

  title={Evidence for the evolution of multiple genomes in arbuscular mycorrhizal fungi},
  author={Gerrit Kuhn and Mohamed Hijri and Ian R. Sanders},
Ancient asexuals directly contradict the evolutionary theories that explain why organisms should evolve a sexual life history. The mutualistic, arbuscular mycorrhizal fungi are thought to have been asexual for approximately 400 million years. In the absence of sex, highly divergent descendants of formerly allelic nucleotide sequences are thought to evolve in a genome. In mycorrhizal fungi, where individual offspring receive hundreds of nuclei from the parent, it has been hypothesized that a… CONTINUE READING
