Analysis of the 5′ terminal nucleotide of PSTVd-sRNAs involved in the cleavage of PSTVd-specific targets according with the degradome category (a) and (b). In PSTVd-infected tomato samples T3 (a) and T4 (b), the 5′ terminal nucleotide of PSTVd-sRNAs involved in host mRNA cleavages classified into the category 0 were U or A, supporting their incorporation into AGO1. When the same analysis was performed considering the false targets identified in the degradome sequencing from mock-inoculated samples (T1 and T2, (c) and (d), respectively), such a bias was not observed.
