Fig. 1

Diversity and distribution of samples and viruses detected in tomatoes and weeds surrounding tomato farms. a Pie chart showing proportion of sample count per sample type, and separately for weed samples, proportion of sample count per plant family. b Map showing the geographical locations where sampling was done. Adjacent to the map is a bar plot summarizing the number of samples collected, and the cumulative number (not unique species) of viruses detected in each sampling locality. c Heatmap showing the diversity of identified viruses by genome composition, their distribution in known virus taxa and by sample type. The known associated eukaryotic host(s) (Kingdom) of each virus taxa are indicated by the icons. The heatmap presents virus counts per family level taxa across sample types where there could be overlaps of virus detections in each sample type. The last column of the heatmap presents the unique number of virus species detected across virus families. d Summary of number of viruses detected according to classification status: known, novel, and unclassified species. e Venn diagram showing the number of identified known and novel viruses (classified under Riboviria and Monodnaviria) found exclusively in tomato or weed composite samples, and the viruses found in both sample types.
