Host range and symptoms

Natural host range and symptoms

Symptoms persist. Symptoms mosaic, ringspot, necrosis.
• Lychnis divaricata, L. chalcedonica, L. coronaria, L. haageana - systemic ringspots, mosaic and necrosis.

Transmission

Virus transmitted by mechanical inoculation; probably transmitted by grafting; transmitted by seed.

Geographical distribution

Spreads in Hungary.

Experimental host range

Many (>9) families susceptible. Experimentally infected plants mostly show ringspots and mosaic.

Diagnostically susceptible host species and symptoms

Purification method

Hunter et al. (1989).

Physical and biochemical properties

Particle morphology

Virions rod-shaped; not enveloped; usually straight; with no clear modal length; of 100-175 nm; 25 nm wide. Basic helix obvious.

Biochemical properties

Virions contain 5 % nucleic acid; 95 % protein; 0 % lipid.

Genome consists of RNA; single-stranded; linear. Total genome size 9 kb. Genome of three parts; largest (or only) genome part the largest 3.8 kb; the 2nd largest 3.3 kb; the 3rd largest 3 kb. Genomic nucleic acid isolated by Hunter et al. (1989).

NCBI sequence data (Entrez search)

Features of proteins

Virion protein(s) one; M_r 23000. Method of preparation: SDS gel electrophoresis.

Replication

Replication does not depend on a helper virus.

Taxonomy and relationships

Hordeivirus

Virus(es) with serologically unrelated virions

Barley stripe mosaic and poa semilatent viruses.

Additional comments on relationships

No detectable cross-hybridization between lychnis ringspot virus, barley stripe mosaic virus and poa semilatent virus genomes and cDNAs transcribed from them.

Best tests for diagnosis

ELISA.
