Potexvirus is a genus of pathogenic viruses in the order Tymovirales, in the family Alphaflexiviridae.
Diseases associated with this genus include: mosaic and ringspot symptoms.
This in turn produces a negative stranded template from which a series of subgenomic RNAs are generated.
The 5' end is about 80 nucleotides in length and typically begins with the sequence GAAAA.
The TGB proteins are conserved among the Allexivirus, Carlavirus, Foveavirus, Furovirus, Hordeivirus, Pecluvirus, Pomovirus and Potexvirus genera.
TGB 1 (molecular weight 23 kDa) is a multifunctional protein.
The virus exits the host cell by tripartite non-tubule guided viral movement.
