Name, Synonyms and Lineage

Synonym(s): Apple stem grooving virus group. Virus is of the family 00.056. Flexiviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is filamentous, flexuous; is cross-banded, is longitudinally striated, and is obliquely striated with a crisscrossed appearance, or has rope-like features (upon uranyl acetate staining) with a length of 600-900-1536 nm and a width of 12-13.87-19 nm. Axial canal is indistinct. Basic helix is obvious, or obscure. Pitch of helix is 3.4-3.635-3.9 nm.

Electron microscopic preparation and references: Virus preparation contains few virions.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.3 g cm-3. There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 96-104-112 S20w. Isoelectric point pH is 4.3. A260/A280 ratio is 1.22-1.46-1.69. The thermal inactivation point (TIP) is at 60-63.25-65°C. The longevity in vitro (LIV) is 2-7-16 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 4.

Nucleic Acid

The Mr of the genome constitutes 5% of the virion by weight. The genome is monopartite, only one particle size is recovered of linear, positive-sense, single-stranded RNA. The complete genome is 6500-7570 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 6500-7570 nucleotides long. The genome has a base ratio of 30.8 % adenine; 20.7 % cytosine; 29.8 % uracil. The genome has a guanine + cytosine content of 39-41 %. The 3'-terminus has a poly (A) tract.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 1 structural protein(s) located in the capsid.

Structural Proteins: Capsid protein has a molecular mass of 24000-26250-27000 Da.

Non-Structural Proteins: Virus-coded non-structural proteins have been isolated and 2 non-structural protein(s) are found.

Lipids

Lipids are not reported.

Transmission and Vector Relationships

Virus is not transmitted by a vector. Virus is transmitted by mechanical inoculation, or not transmitted by mechanical inoculation; transmitted by grafting; transmitted by seeds, or not transmitted by seeds.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in several families, few families. Susceptible host species are found in the Family Aizoaceae, Amaranthaceae, Caryophyllaceae, Chenopodiaceae, Cucurbitaceae, Labiatae, Leguminosae-Papilionoideae, Nandinaceae, Oleaceae, Rosaceae, Rutaceae, Scrophulariaceae, Solanaceae, Tetragoniaceae. The following species were susceptible to experimental virus infection: Aizoaceae, Amaranthaceae, Amaranthus retroflexus, Beta macrocarpa, Beta vulgaris, or Chenopodiaceae, Chenopodium amaranticolor, Chenopodium capitatum, Chenopodium murale, Chenopodium quinoa, Citrus aurantifolia, Citrus excelsa, Citrus limon, Citrus medica, Citrus sinensis, Citrus sinensis x Poncirus trifoliata, or Cucurbitaceae, or Fabaceae, Lamiaceae, Malus sylvestris, Nandina domestica, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana glutinosa, Nicotiana glutinosa x N. clevelandii, Nicotiana rustica, Nicotiana tabacum, Petunia x hybrida, Phaseolus vulgaris, Poncirus trifoliata, Poncirus trifoliata x Citrus paradisi, Prunus cerasus, or Rosaceae, Scrophulariaceae, Silene armeria, or Solanaceae, Syringa vulgaris, Tetragonia tetragonioides, Trifolium incarnatum, Vicia faba, Vigna unguiculata.
