Data collated by C. Büchen-Osmond, 1987. Revised by R.F. Lee, 1989.

Nomenclature

Synonyms

citrange stunt virus (Roistacher, 1988).

Acronym

CTLV

ICTV decimal code

13.0.1.0.002

Host range and symptoms

Natural host range and symptoms

Symptoms vary seasonally.
• Citrus limon cv. Meyer - tatter leaf; blotchy and malformed leaves.
• C. excelsa - tatter leaf or symptomless.
• C. sinensis - symptomless.
• Poncirus trifoliata - interveinal chlorosis.

Transmission

Probably is moved and dispersed only in infected budwood. Virus transmitted by mechanical inoculation; transmitted by grafting; transmitted by seed (in lily).

Ecology and control

Studies reported by Takahara et al. (1988); Koizumi (1984); Navarro et al. (1989); Miyakawa (1980); Roistacher et al. (1980).

Geographical distribution

Spreads in the African region, the Eastern Asian region, the North American region, and the Pacific region; Australia, China, Japan, Korea D.P.R. (North), Korea Republic, South Africa, Taiwan, and the USA. Found, but with no evidence of spread, in N.S.W., Australia.

Experimental host range

Several (3-9) families susceptible to few (<3) families susceptible. Experimentally infected plants mostly show tatter leaf, systemic mottle.

Diagnostically susceptible host species and symptoms

• Citrus excelsa - tatter leaf.
• Poncirus trifoliata - interveinal chlorosis.
• Nicotiana clevelandii, N. glutinosa - chlorotic veinal blotching.
• Chenopodium quinoa - chlorotic local lesions, systemic mottle and curling.
• Citrus sinensis × Poncirus trifoliata cv. Rusk, Poncirus trifoliata × Citrus paradisi cv. Swingle - leaf malformation and twisted stems.

Maintenance and propagation hosts

Citrus excelsa, Nicotiana clevelandii, N. glutinosa, Vigna unguiculata.

Assay hosts (Local lesions or Whole plants)

Purification method

Semancik and Weathers (1965).

Physical and biochemical properties

Particle morphology

Virions filamentous; usually flexuous; with a clear modal length; of 650 nm; 19 nm wide. Basic helix obvious; pitch of basic helix 3.4 nm.

Biochemical properties

Genome consists of RNA; single-stranded.

NCBI sequence data (Entrez search)

Sequence database accession code(s)

• D14455 Em(43)_vi:Ctlvcc Gb(89)_vi:Ctlvcc Citrus tatter leaf virus RNA for viral polymerase protein, cell to cell movement protein
• D16368 Em(40)_vi:CTLA Gb(84)_vi:CTLA Citrus tatter leaf virus RNA. 3/94 2,956bp.

Features of proteins

Virion protein(s) one; M_r 27000.

Taxonomy and relationships

Capillovirus

Virus(es) with serologically related virions

Apple stem grooving virus.

Comments and References

General comments

Recent tests indicate that this virus is probably a closely related strain of apple stem grooving capillovirus rather than a distinct virus (Ohira et al., 1994).
