Figure 10: Phylogenetic correlations for miR168 sequences.

(a) Heatmap for the most abundant sequences of the miR168-5p family. Each row represents a miR168-5p sequence and each column a plant species. Colours correspond to a base 10 logarithm transformation of sequence abundance in RPM, from black (absent) to red (high abundance). Arrows indicate the most abundant sequence in each group. (b) Three distinct miR168-5p sequences represent the majority of miR168-5p sequences. Colour bars represent the relative abundance of miR168-5p sequences. 1, sequences not present in version 19 of miRBase.
