[2][3][4] The recognized genera are: The unassigned species is Coconut foliar decay virus.

[2] Viruses in the family Nanoviridae are non-enveloped, with icosahedral and round geometries, and T=1 symmetry.

[3] After infection of a host cell, the small DNA molecules that have become encapsidated with the genomic ssDNA act as primers.

They bind to complementary regions and help in initiation of DNA synthesis by host polymerases.

The virus exits the host cell by nuclear pore export, and tubule-guided viral movement.
