Transmission

Transmitted by a vector; an insect; Aphis nerii, Aphis spiraecola, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by contact between plants.

Ecology and control

Sources of host-range data

Charudattan et al. (1980).

Physical and biochemical properties

Properties of particles in sap

TIP: 56-58 °C. LIV: 2-2.5 days. DEP: log₁₀ minus 2-3. Leaf sap contains few virions.

Purification method

Hiebert and Charudattan (1984).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 741 nm. Axial canal obscure. Basic helix obscure.

Biochemical properties

Genome consists of RNA; single-stranded.

Features of proteins

Virion protein(s) one; M_r 32000; coat protein.

Virus-coded non-virion proteins identified by genomic sequence analysis (Hiebert and Charudattan (1984)); five proteins found. M_r of the largest 81000; helper component related. M_r of 2nd largest 70000; cylindrical inclusion. M_r of 3rd 53000; nuclear inclusion. M_r of 4th 49000; nuclear inclusion. M_r of 5th and smaller 40000; function unknown.

Cytopathology

Virions found in mesophyll and epidermis. Inclusions present in infected cells; are pinwheels; they do not contain virions.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically unrelated virions

Bean common mosaic, bidens mottle, blackeye cowpea mosaic, dasheen mosaic, lettuce mosaic, papaya ringspot, pepper mottle, potato Y, soybean mosaic, tobacco etch, tobacco veinal mottle, tobacco etch and turnip mosaic viruses.

Additional comments on relationships

The 49kDa and 53kDa proteins produced by in vitro translation react with antisera to tobacco etch (TEV) nuclear proteins and the 32kDaprotein with antiserum to TEV capsid protein; the cylindrical inclusion protein of araujia mosaic is serologically related to that of dasheen mosaic virus but not TEV; and the 81kDaprotein of araujia mosaic virus reacted with antiserum to the helper component of tobacco vein mottling virus.

Comments and References

General comments

Charudattan et al. (1980) suggest that the virus might be used to control Morrenia weeds in citrus orchards in Florida, U.S.A.
