Recombination in Plant DNA Viruses
ByThomas Frischmuth
Pages 26

The evolution of plant viruses proceeds hy natural mutation and recombination. Natural occurrence of mutations and recombination between plant viruses has been deduced from sequence analysis of virus isolates for RNA as well as DNA viruses. Besides recombination, pseudorecombination between multipartite viruses has also been recognized as a driving force for the evolution of new viruses (sec Figure 15.1).
