Insights into Emerging Begomovirus–Deltasatellite Complex Diversity: The First Deltasatellite Infecting Legumes

Begomoviruses and associated DNA satellites are involved in pathosystems that include many cultivated and wild dicot plants and the whitefly vector <i>Bemisia tabaci</i>. A survey of leguminous plants, both crops and wild species, was conducted in Venezuela, an understudied country, to d...
