Figure 5.

Analysis of viroid‐derived small RNAs (vd‐sRNAs) recovered from the phloem sap of infected cucumber plants. (A) Size distribution of the vd‐sRNA population detected in the phloem of infected cucumber plants. The proportional accumulation of sense and antisense vd‐sRNAs is also illustrated. (B) Relative abundance of the most representative size classes of sense and antisense vd‐sRNAs recovered from leaves (left) and phloem (right). (C) Accumulation values in leaves and phloem of unique sense and antisense 21‐ and 22‐nucleotide vd‐sRNAs.
