(a) Total number and quality categorization (from 0 to 4, where 0 represents the strongest evidence for true cleavage products) of mRNAs targeted by PSTVd-sRNAs in PSTVd-infected (T3 and T4) and of non-PSTVd specific (false positive) mRNAs targets in mock-inoculated (T1 and T2) tomato biological replicates identified by degradome analysis; (b) number of PSTVd specific and non-specific mRNA targets in each viroid-infected tomato plant (T3 and T4) and degradome category. The PSTVd-specific mRNA targets were those not identified in any of the two mock-inoculated tomato replicates (T1 and T2), which are all considered as false positives.
