Book Description

The evolution of viruses has been a topic of intense investigation and theoretical development over the past several decades. Numerous workshops, review articles, and books have been devoted to the subject. Medical practitioners have recognized the importance of viral evolution when treating patients with viral diseases. Farmers have recognized the importance of understanding virus evolution in combating emerging viral diseases in their crop plants. As with any field where knowledge is rapidly expanding, many controversies have also arisen about the nature of virus evolution, how to describe virus populations, how to analyze sequence data and estimate phylogenies, etc. Differing points of view will also be found in the various chapters of this book, and I leave it to the readers to decide for themselves which side they find most helpful. In some cases it seems to me that all sides are correct. In other cases, future historians will decide. This book focuses on the evolution of plant viruses, although some chapters also draw on the more extensive knowledge of animal viruses. It covers topics on evo- tionary mechanisms, viral ecology and emergence, appropriate methods for analysis, and the role of evolution in taxonomy. It includes RNA viruses, DNA viruses, integrated viruses and viroids.

Author Bio

Marilyn J Roossinck is Professor Emeritus of the Penn State College of Agricultural Sciences and he research focused on covering adaptation of extreme environments with microbes and virus ecology.

She lives in Bellefonte, Pennsylvania.

Research Interests

Our focus in the Roossinck lab is on virus-plant and virus-fungus-plant interactions in virus evolution and ecology.

We use Cucumber mosaic virus (CMV) as a model virus for experimental evolution studies, including generation and maintenance of quasispecies, rates of recombination, and polymerase fidelity.

We are interested in how plants use viruses in adaptation to extreme environments. Fungal viruses are involved in plants adapting to geothermal soils in Yellowstone National Park, and acute plant viruses confer drought and cold tolerance to plants. We are studying the mechanisms of these interactions.

We are interested in the biodiversity of plant viruses. We are studying viruses in wild plants in Costa Rica using next-gen sequence analysis of viral RNA from individual plants. To date we have collected about 14,000 plants and have analyzed about half of them.
