An Emerging Model System: Arabidopsis as a Viral Host Plant
The model plant Arabidopsis thaliana has been established as a host for representatives of many of the major groups of plant viruses. These viruses use a variety of strategies to replicate and traffic their genomes within compatible host plants. The development of Arabidopsis as a host for these diverse viruses provides opportunities to apply genetic and reverse genetic approaches to the complex interactions that are not feasible or practical in many of their agronomically important hosts. In this chapter, we summarize the amazing array of viruses that have been shown to infect one or more Arabidopsis ecotypes, describe natural variation in the ability of these ecotypes to support systemic infections, and discuss host genes that have been identified through a variety of approaches that are involved in movement or limit virus spread in Arabidopsis.
