Interspecies Recombination-Led Speciation of a Novel Geminivirus in Pakistan

open access: yesViruses, 2022
Recombination between isolates of different virus species has been known to be one of the sources of speciation. Weeds serve as mixing vessels for begomoviruses, infecting a wide range of economically important plants, thereby facilitating recombination.
