|---|---|---|---|
| Y shaped | I shaped | PTE | BTE |
| Tombusvirus (dicot infecting) | Tombusvirus (monocot infecting) | Panicovirus | Luteovirus |

The column heads identify the four different classes of 3′CITE contained in the wt and hybrid genomes used in this study. The bottom rows list the genera that contain viruses naturally harboring each type of 3′CITE. The genera of origin for the specific 3′CITEs engineered into hybrid CIRV genomes are shown in bold, and the predicted secondary structures of these elements are shown in Fig. 1.
