siRNA production from various PHAS loci upon viral infection. a Pie diagram showing the PHAS loci with more than five-fold changes in total 21-nt siRNA production in papaya leaves infected by Papaya ringspot virus as compared to that in healthy leaves. The number of PHAS locus or loci for each gene category showing induced or suppressed expression is indicated. b–d Specific examples of PHAS loci derived from disease-resistant genes (b), auxin-related genes (c), and ethylene-responsive transcription factor genes (d), which showed differential expression of siRNAs in healthy and infected leaves
