Fig. 2: sRNA-seq revealed natural ToMV infections in plants.

a The percentage of virus-derived reads in the WT and dcl2b samples. b The length distribution of virus-derived total reads in the WT and dcl2b from greenhouse II. c The distribution patterns of ToMV, TMMV, TBRFV, and other viruses. d Phylogenetic analyses of 34 Tobamoviruses. A phylogenetic analysis is shown in the left panel. The three viruses analyzed in the manuscript are marked in red. The genome-wide distributions of virus-derived reads are displayed on the right. e An RT-PCR analysis of specific fragments of ToMV and tobacco mosaic virus (TMV)
