Fungally‐transmitted viruses of cereals in the UK¹

Abstract

The distribution of two UK strains of barley yellow mosaic virus has been studied and both have been transmitted experimentally by Polymyxa graminis. cDNA hybridization studies support the suggestion that the strains should be considered distinct viruses. Oat mosaic and oat golden stripe (OGSV) viruses also occur in the UK. OGSV is a furovirus related to wheat soil‐borne mosaic furovirus: it has particles of two lengths and a bipartite genome.

The nucleotide sequence of RNA 2 of barley yellow mosaic virus

“…3.6 kb) and is a causal agent of a serious disease of increasing agronomic importance of winter barley cultivars in European and Asiatic countries (Inouye & Saito, 1975;Huth et al, 1984;Huth, 1988). The virus is transmitted by the soilborne fungus Polymyxa graminis (Adams et al, 1989), hence control measures are difficult. BaYMV was originally classified as a potyvirus as it has several properties in common with these viruses (Hollings & Brunt, 1981;Shukla & Ward, 1989).…”

The complete nucleotide sequence of RNA 1 of a German isolate of barley yellow mosaic virus and its comparison with a Japanese isolate

“…This classification was based on their particle morphology and the induction of characteristic cytoplasmic cylindrical inclusion bodies in the cereal hosts (Hibino et al, 1981;Ebrahim-Nesbat & Zerlik, 1984;Huth et al, 1984). However, in contrast to potyviruses this group of viruses has a genome consisting of two RNA species (Huth, 1988;Usugi et al, 1989) and is transmitted by the fungus Polymyxa graminis (Adams et al, 1989;Brunt, 1989). In addition, most of these fungus-transmitted viruses are serologically related to each other but most do not show any serological relationship to potyviruses transmitted by other vectors (Huth et al, 1984;Ehlers & Paul, 1986;Adams et al, 1987;Usugi et al, 1989).…”

Fungally-transmitted Rod-shaped Plant Viruses: Biology, Transmission and Molecular Pathology

“…Furoviruses usually have particles of two or more lengths about 20 nm in diameter and up to 400 nm long (Table 3). Bymoviruses have flexuous, filamentous rods and have particles typically of two lengths (around 300 nm and 600 nm although those of WSSMV appear to be longer) and diameter of about 13 nm (Adams et al, 1989). The genomes of viruses transmitted by plasmodiophoromycetes are usually bipartite but BNYVV has four components and PMTV contains three distinct RNA components (see Fig.…”
