Impact of Cultivated Hosts on the Recombination of Cucumber Mosaic Virus.

ABSTRACT: Cucumber mosaic virus (CMV) is one of the most successful viruses known, infecting over 1,200 species of plants. Like other single-stranded RNA viruses, CMV is known to have a high potential for population diversity due to error-prone replication and short generation times. Recombination is also a mechanism that allows viruses to adapt to new hosts. Host genes have been identified that impact the recombination of RNA viruses by using single-cell yeast systems. To determine the impact that the natural plant host has on virus recombination, we used a high-recombination-frequency strain of CMV, LS-CMV, which belongs to subgroup II, in three different cultivated hosts: Capsicum annuum cv. Marengo (pepper), Nicotiana tabacum cv. Xanthi nc (tobacco), and Cucurbita pepo cv. Black Beauty (zucchini
