Global Weed-Infecting Geminiviruses

Weeds are invasive species that grow along with cultivated plants due to their high phenotypic plasticity. They serve as reservoirs of geminiviruses during off-season for main crops and provide the source of virus inoculum during their plantation. Geminiviruses are single-stranded DNA viruses enclosed in icosahedral geminate particles. These viruses can be either monopartite or bipartite, depending upon the number of genomic circles present. The members of genus Begomovirus are responsible for huge economic crop losses and are transmitted through insect vector Bemisia tabaci. The majority of the weed-infecting monopartite begomoviruses are associated with Betasatellite genus of Tolecusatellitidae family and alphasatellites. Geminiviruses are reported to infect a variety of weeds in South-east Asia, Mediterranean region, Western Europe (mainly Spain and France), Africa, Latin America, Central America, Caribbean region, and Australia. Weeds harbor the mixed infection of viruses; therefore, these plants serve as melting pots for recombination and evolution of begomoviruses. This chapter presents the geminivirus infection on weeds, their recombination, and their spread to newer hosts.
