Abstract
As is the case with all living entities, reproduction of plant viruses may result in the generation of individuals that differ genetically from their parents, which are called mutants or, more vaguely, variants. Hence, populations of plant viruses are genetically heterogeneous, and the frequency distribution of genetic variants in the population (i.e. the genetic structure of the population) may change with time. This process is called evolution. A major area in the study of evolution aims at understanding the mechanisms of evolution and how they shape the genetic structure of populations. Another area aims at understanding the evolutionary history of organisms and the resulting taxonomic relationships among them. Both aspects of evolutionary studies have a long history in plant virology and have attracted much interest in the last few decades, particularly since the availability of molecular analytical techniques, such as those allowing the rapid determination of nucleotide sequences. In this chapter we will review how the analysis of plant virus evolution has itself evolved. We do not pretend to make an exhaustive review, but we hope rather to put emphasis on the concepts that have driven the development of the field, illustrated with references to the publications that introduced those concepts or that, in our opinion, best developed them.
