Fig. 6.

Circos plots for interactive visualization of the genomic origin of various tncRNAs subclasses generated from parental tRNAs and the relative position of tRNA genes on the genome for individual plants. The relative abundance of various tncRNA subtypes and tRNA gene density with respect to the genomic location is shown by the heatmap. From the outer to the inner circle, the first ring represents the chromosomes, the next ring (second) shows the GC content of the chromosomes. The third, fourth, fifth, sixth, and seventh ring shows the genomic tRNA region producing tRF-5, tRF-3(CCA), tRF-1, 5′ tRH, and 3′tRH respectively. The innermost ring shows the tRNA gene distribution across the genome. tncRNA/tRNA-rich regions are shown in purple (highest density) and tncRNA/tRNA-poor regions are shown in the red (minimum density) spectrum.
