00.057.0.01.451 Watermelon mosaic virus1
Virus infects plants.
Description is on taxonomic level of species. Virus is an approved species in the genus. Virus belongs to the genus Potyvirus (VC 00.057.0.01. ); family Potyviridae (VC 00.057. ).
Virus first reported in Citrullus lanatus. Reference(s): Webb (1965).
Total genome length is 11400 nt. The largest segment 11400 nt. NCBI Taxon ID: 12205. The 5' end of the genome has a genome-linked protein (VPg). Poly A region present. Poly A region at the 3´ terminus (Nagel and Hiebert, 1985). The 3´ end cloned and expressed in E. coli. Genomic nucleic acid isolated by Brakke and van Pelt (1970); de Mejia (1984); Hiebert et al. (1984); de Mejia et al. (1984).
Function of Helper and Satellite Viruses. Virions associated with helper virus, but independent from its functions during replication.
Cytopathology. Virions found in mesophyll, epidermis and phloem; in cytoplasm. Inclusions present in infected cells. Inclusions are amorphous X-bodies and pinwheels. They do not contain virions.
Cucurbita pepo - mosaic, green blistering, leaves and fruit
malformed.
Citrullus lanatus, Cucumis melo, Melothria pendula,
Momordica charantia - mosaic, mottling, leaves malformed.
Families containing susceptible hosts: Caricaceae (1/1), or Chenopodiaceae (2/2), or Cucurbitaceae (10/10), or Leguminosae-Papilionoideae (1/2).
Families containing insusceptible hosts: Boraginaceae (1/1), or Caricaceae (1/1), or Cucurbitaceae (1/10), or Leguminosae-Papilionoideae (1/2), or Solanaceae (1/1).
Comments on host-range: many watermelon mosaic virus 2 isolates (Purcifull, Hiebert and Edwardson, 1984) do not infect Luffa acutangula, and therefore this species has been used to obtain PRSV isolates free from watermelon mosaic virus 2 (Webb, 1965; Greber, 1978; D. Purcifull, unpublished data). Sources of host-range data: Wang et al. (1978); Adlerz (1972a; 1972b); Milne and Grogan (1969); Purcifull and Hiebert (1979); Yeh et al. (1984).

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses (ICTV) by Dr Cornelia Büchen-Osmond, is written in DELTA. The virus descriptions in ICTVdB are coded by ICTV members and experts, or by the ICTVdB Management using data provided by the experts, the literature or the latest ICTV Report. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations from the encoded descriptions are automatically generated and formatted for display on the Web.
