Members of the family Closteroviridae have been traditionally defined as plant viruses with thread-like particles having messenger-sense single-stranded RNA, the largest genomes among RNA plant viruses. Individual virus species are distributed worldwide and some of them cause devastating crop losses. The natural host range usually narrow. Diseases symptoms are yellowing type or pitting and/or groowing of the woody cylinder. Infection systemic, but usually limited to the floem. Natural vectors are aphids, whiteflies, pseudococcids, coccids and mealybugs. Trans­mission is semipersistant. Closteroviruses contains 9-13 ORFs flanked by 5'- and 3'- untranslated regions with different length. The genome strategy is based on  polyprotein precessing, +1 ribosomal frame­shift and formation of subgenomic RNAs. Common features of closteroviruses that encode a homologue of HSP70 molecular chaperones found in all cells (HSP70h) and a duplicate (CPd) of the coat protein gene.
