Genetic diversity of sweet potato begomoviruses in the United States and identification of a natural recombinant between sweet potato leaf curl virus and sweet potato leaf curl Georgia virus.

Abstract excerpt

In the United States, two sweet potato begomoviruses, sweet potato leaf curl virus (SPLCV) and sweet potato leaf curl Georgia virus (SPLCGV), were previously identified in Louisiana. In recent years, at least seven additional sweet potato begomoviruses have been identified in other parts of the world. In an effort to determine the genetic diversity and distribution of sweet potato begomoviruses in the U.S., we...
