Begomovirus populations in single plants are complex and may include both well-adapted and poorly-adapted viruses.

ABSTRACT: Begomoviruses (single-stranded DNA plant viruses transmitted by whiteflies) are economically important pathogens causing epidemics worldwide. Tomato-infecting begomoviruses emerged in Brazil in the 1990's following the introduction of Bemisia tabaci Middle East-Asia Minor 1. It is believed that these viruses evolved from indigenous viruses infecting non-cultivated hosts. However, tomato-infecting viruses are rarely found in non-cultivated hosts, and vice-versa. It is possible that viral populations in a given host are composed primarily of viruses which are well adapted to this host, but also include a small proportion of poorly adapted viruses. Following transfer to a new host, the composition of the viral population would shift rapidly, with the viruses which are better adapted to the ne
