Nomenclature

ICTV decimal code

57.0.1.T.D.06

Host range and symptoms

Natural host range and symptoms

Kalanchoe blossfeldiana - mosaic of light and dark green areas ("green island mosaic disease").

Transmission

Transmitted by a vector; an insect; Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Spreads in the Eurasian region; Denmark. Found, but with no evidence of spread, in USA, probably.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show local lesions.

Diagnostically susceptible host species and symptoms

Chenopodium amaranticolor, C. quinoa - chlorotic and necrotic local lesions; not systemic.

Diagnostically insusceptible host species

• Beta vulgaris, Brassica campestris ssp. pekinensis, Cucurbita pepo, Nicotiana benthamiana, N. occidentalis, N. tabacum, Phaseolus vulgaris and Pisum sativum.

Maintenance and propagation hosts

Chenopodium quinoa, Kalanchoe blossfeldiana.

Assay hosts (Local lesions or Whole plants)

Chenopodium quinoa (L), Kalanchoe blossfeldiana (W).

Susceptible host species

• Chenopodium amaranticolor

Physical and biochemical properties

Particle morphology

Virions filamentous; usually flexuous; with a clear modal length; of 724 nm.

Biochemical properties

Genome consists of RNA; single-stranded. Poly A region present. Nucleotide sequence references: Husted et al. (1994).

Features of proteins

Virion protein(s) one; M_r 33000; coat protein.

Taxonomy and relationships

Possible Potyvirus: Potyviridae

Virus(es) with serologically unrelated virions

Bean common mosaic, bean yellow mosaic, carnation vein mottle, celery mosaic, dasheen mosaic, leek yellow stripe, onion yellow dwarf, pea seed-borne mosaic, potato Y and papaya ringspot viruses.
