subterranean clover red leaf luteovirus.
virus - dwarfing strain (SDV-D), soybean dwarf - leaf yellowing strain
ICTV decimal code
Host range and symptoms First reported
in Glycine max; from Hokkaido, Japan; by Tamada et al. (1969);
Natural host range and symptoms
- Glycine max, Trifolium pratense - puckering, rugosity and
- Pisum sativum - mild yellowing of older
- Phaseolus vulgaris - yellowing of leaves and stunting.
- Gomphrena globosa, Erodium moschatum, Trifolium subterraneum, Vicia
sativa, Calandrinia caulescens - leaf reddening.
- Beta vulgaris,
Lupinus albus, Lupinus angustifolius, Medicago polymorpha - leaf
- Trifolium repens, T. pratense - no symptoms.
- Vicia faba, Vicia articulata - leaf yellowing, rolling.
Transmitted by a vector; an insect;
Acyrthosiphon (Aulacorthum) solani (some isolates also by
Acyrthosiphon pisum); Aphididae. Transmitted in a persistent manner.
Virus retained when the vector moults; does not multiply in the vector; not
transmitted congenitally to the progeny of the vector; does not require a helper
virus for vector transmission; not transmitted by mechanical inoculation; not
transmitted by contact between plants; not transmitted by seed.
Ecology and control

Properties of particles in sap
45-50 °C (when tested by insect injection or membrane feeding). LIV: more than
14 days. DEP: log10 minus 2-3. Infectivity of sap decreased by treatment with
di-ethyl ether. Leaf sap contains few virions. Electron microscopy: not
necessary to fix the virions.

Genome consists of RNA; single-stranded; linear. Total genome size 5.861
kb. Genome unipartite; largest (or only) genome part 5.861 kb. Genomic nucleic
acid isolated by Waterhouse et al. (1987). Poly A region absent.

Features of proteins
Virion protein(s) two;
Mr of the major 24000; coat protein. Mr of 2nd largest
55000; possibly a read through protein from the coat protein. Method of
preparation: Ashby and Kyriakou (1982).
Virions found in phloem; in cytoplasm and
in cell vacuoles. Inclusions absent from infected cells. Other cellular changes:
phloem necrosis, starch accumulates in chloroplasts of epidermis and mesophyll
Virus(es) with serologically related virions
Beet western yellows, barley yellow dwarf (strains RPV and MAV), bean
leaf roll, potato leafroll and tobacco necrotic dwarf viruses. Subterranean
clover red leaf virus is so closely related that it is often considered to be
the same species.
Best tests for diagnosis
tests using monoclonal antibodies.
A severe stunting
disease of soybean (Glycine max), African soybean dwarf, was first noted
in 1975 in Nigeria (Rossel and Thottappilly, 1983). The causal virus was
transmitted in the persistent manner by Bemisia tabaci. It resembles that
caused by soybean dwarf luteovirus, which is aphid-borne. Some soybean genotypes
(e.g. cvs Improved Pelican, Indo 100 and Bossier) are very resistant to
the Nigerian virus (Rossel and Thottappilly, 1985).
