Abstract

Begomoviruses (genus Begomovirus, family Geminiviridae) rank among the top of the most important plant viruses causing disease of severe consequences in economically and socially relevant crops. From the early 1990s, a rapid emergence and geographic expansion of begomoviruses has occurred worldwide. As a result, these viruses have become the most destructive group of plant viruses in tropical and subtropical regions of the world. Their emergence is associated with the emergence of populations of the insect vector, the whitefly Bemisia tabaci, probably due to increased plant trading between distantly separated geographical regions and changes in agricultural practices. Human activity seems to have been a major factor promoting emergence of begomoviruses. Other factors driving emergence are discussed in this contribution, and examples of emergence of begomovirus diseases in economically important crops are provided read more ...
