Abstract
During the last thirty years progress in understanding the mechanistic aspects of virus-plant interactions have been remarkable, notably in aspects such as genome replication, movement within the infected host or pathogenesis and resistance. Progress in understanding the pPopulation dynamics and genetics of plant infection by viruses has not been parallel. However, understanding the kinetics of plant colonisation and the genetic structure of the within-host virus population is necessary for addressing many issues of plant-virus interaction and of virus evolution. The quantitative aspects of plant infection and colonisation by viruses were mostly addressed at early stages of plant virology, when many detailed studies, the basis of mathematical modelling, were published. These issues have not been re-examined using molecular techniques. Recent work has focussed on the description of the genetic structure of the virus population at the organ and the plant level. Data suggest that in spite of huge fecundity, the effective numbers of the within host virus population may be small due to severe population bottlenecks at each stage of plant infection and colonisation, what results in a spatially structured population.
