SW13 were obtained. YTMMV-Kalbarri shared 97% nucleotide pairwise identity with the sequence of the type isolate YTMMV-Cervantes. The sequence PZSV-SW13 shared greatest sequence identity with the partial sequence of an Australian isolate of PZSV also from a wild plant, and with a sunflower-derived isolate of PZSV from Argentina. An experimental host range study was done of YTMMV-Kalbarri using cultivated and wild solanaceous and nonsolanaceous plants. Most solanaceous plants became systemically infected, with symptoms of systemic infection ranging from asymptomatic to whole plant necrosis. Based on these studies, we suggest that YTMMV has the potential to become a pathogen of commercial species of Solanaceae. This study provides further evidence that PZSV is present in wild plants in Australia, in this case an indigenous host species, and possible routes by which it invaded Australia are discussed.
