In contrast to other picornaviruses, the genome layout of dicipiviruses exhibits two ORFs separated by an intergenic region (IGR) that functions as an IRES to translate the second ORF. The IGR-IRES shows no similarity to the equivalent region in members of the Dicistroviridae.

Tobraviruses have a bipartite genome, a “30K”-like cell-to-cell movement protein and are transmitted by trichodorid nematodes.
Pomoviruses have three genomic RNAs, a “triple gene block” set of cell-to-cell movement proteins and are transmitted by root-infecting vectors in the family Plasmodiophorales, once described as fungi but now classified as Cercozoa.
