Acronym

NV

ICTV decimal code

57.0.1.T.059

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Nerine sarniensis - chlorotic streaking.
• Nerine bowdenii - chlorotic mosaic.

Transmission

Transmitted by a vector; an insect; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by contact between plants.

Geographical distribution

Spreads in the Netherlands and the UK.

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Nicotiana clevelandii - systemic chlorotic vein-banding.
• Chenopodium quinoa - chlorotic local lesions.
• Chenopodium amaranticolor - small chlorotic local lesions.
• Chenopodium murale - diffuse chlorotic local lesions.
• Hyoscyamus niger - chlorotic local lesions.
• Nicotiana benthamiana - chlorotic local lesions, then systemic chlorotic vein-banding.
• Tetragonia tetragonioides - green chlorotic rings.

Physical and biochemical properties

Properties of particles in sap

TIP: 65 °C. Leaf sap contains few virions. Electron microscopy: ISEM best for finding virions in sap.

Purification method

Phillips: Homogenise infected leaves in 0.25M phosphate: 0.1M ascorbic acid: 0.14M mercaptoacetic acid (3:9:1 vols/wt; pH7.0), then ether and finally carbon tetrachloride (1:1 vols). Stir for 15 minutes then two cycles differential centrifugation.

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 780 nm; 12 nm wide. Axial canal obscure. Basic helix obscure.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in all parts of the host plant.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Potato Y (SDI 5), henbane mosaic (SDI 8), clover yellow vein, (SDI 9) and alstroemeria mosaic (SDI 10) viruses.

Virus(es) with serologically unrelated virions

Bean yellow mosaic (gladiolus and crocus strains), carnation vein mottle, freesia mosaic, hippeastrum mosaic, iris mild mosaic, narcissus degeneration, narcissus late season yellows, pea mosaic, pepper veinal mottle, tobacco severe etch, and watermelon mosaic viruses.
