Estimation of population bottlenecks during systemic movement of tobacco mosaic virus in tobacco plants.

Abstract excerpt

More often than not, analyses of virus evolution have considered that virus populations are so large that evolution can be explained by purely deterministic models. However, virus populations could have much smaller effective numbers than the huge reported census numbers, and random genetic drift could be important in virus evolution. A reason for this would be population bottlenecks during the virus life cycle....
