Nomenclature

Acronym

MacMV

ICTV decimal code

57.0.U.2.001

Host range and symptoms

Natural host range and symptoms

Symptoms persist and vary seasonally. Symptoms mosaic.
• Maclura pomifera - interveinal mosaic, occasional vein-banding and leaf distortion especially in spring and autumn (Plese and Milicic, 1973; Plese and Stefanac, 1976).

Transmission

Experimentally transmitted by the aphid Myzus persicae and is non-persistent. Virus transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Spreads in the former Yugoslavia.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show local mild symptoms or no symptoms.

Diagnostically susceptible host species and symptoms

• Amaranthus caudatus, Chenopodium album - chlorotic local lesions.
• C. amaranticolor - circular necrotic local lesions.
• C. quinoa - latent local infection.
• Nicotiana clevelandii - mild systemic mosaic.
• N. megalosiphon - latent systemic infection.
• Tetragonia tetragonioides - diffuse chlorotic local lesions.

Diagnostically insusceptible host species

Brassica campestris ssp. rapa, Datura stramonium, Petunia × hybrida, Phaseolus vulgaris.

Maintenance and propagation hosts

Nicotiana clevelandii, Tetragonia tetragonioides.

Assay hosts (Local lesions or Whole plants)

Virions found in leaves; in cytoplasm. Inclusions present in infected cells; are amorphous X-bodies and pinwheels.

Taxonomy and relationships

macluravirus

Virus(es) with serologically related virions

Bean yellow mosaic virus (Plese et al., 1979). Weak reactions were observed with antisera to poplar mosaic and narcissus latent carlaviruses (Plese et al., 1979; Mowat et al., 1991).

Virus(es) with serologically unrelated virions

Bean common mosaic, bidens mottle, clover yellow vein, gloriosa stripe mosaic, lettuce mosaic, narcissus yellow stripe, pea necrosis, pea seed borne mosaic, plum pox, potato Y, tobacco etch and turnip mosaic viruses.
