suggests a replication mode like that of poleroviruses, whereas the coat protein sequence is closely related to that of sobemoviruses.

Structure

Viruses in ''Polemovirus'' are non-enveloped, with icosahedral geometries, and T=3

symmetry Symmetry () in everyday life refers to a sense of harmonious and beautiful proportion and balance. In mathematics, the term has a more precise definition and is usually used to refer to an object that is Invariant (mathematics), invariant und ...

Life cycle

Viral replication is

cytoplasm The cytoplasm describes all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles and excluding the nucleus in eukaryotic cells. The material inside the nucleus of a eukaryotic cell a ...

ic, and is lysogenic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Commercial cultivars of ''Euphorbia pulcherrima'' serve as the natural host.
