The ever increasing diversity of begomoviruses infecting non‐cultivated hosts: new species from Sida spp. and Leonurus sibiricus, plus two New World alphasatellites

Begomoviruses (whitefly‐transmitted, single‐stranded DNA plant viruses) are among the most damaging pathogens causing epidemics in economically important crops worldwide. Besides cultivated plants, many weed and wild hosts act as virus reservoirs where recombination may occur, resulting in new species. The aim of this study was to further characterise the diversity of begomoviruses infecting two major weed genera, Sida and Leonurus . Total DNA...
