In Kenya around Lake Victoria rice is affected by a hitherto undescribed virus for which the name Rice Yellow Mottle Virus (RYMV) is proposed. The virus was easily transmitted mechanically to rice and to Oryza barthii and Oryza punctata, but not to Oryza eichingeri, barley, bulrush millet, durum wheat, finger millet, maize, oats, rye, sorghum, wheat, sugarcane, 20 other monocotyledonous and 9 dicotyledonous plant species.The disease is characterised by stunting and reduced tillering of the rice plant, crinkling, mottling and yellowish streaking of the leaves, malformation and partial emergence of the panicles, and sterility. In severe cases the plant may die. RYMV is stable and highly infective.The vector is the beetle Sesselia pusilla Gerstaeker (fam. Chrysomelidae, Galerucinae). The beetle has been identified by Mr John A. Wilcox, New York State Museum and Science Service, New York. S. pusilla transmitted the virus for at least five successive days after feeding on an infective plant.Purified virus preparations consisted of polyhedral particles about 32 m/x in diameter. The sedimentation coefficient was 116S.

“…at 1000 X g. Purified virus fractions were also prepared from the discs. With TMV-infected tobacco discs, we used the technique described by TANIGUCHI (1962); with BMV-infected barley leaf pieces, a modification of the technique proposed by PROLL and SCHMIDT (1964) was used: the leaf tissue was homogenized in phosphate buffer 0.1 M pH5.5 and2 volumes of the homogenate were shaken with 1 volume of chloroform. After centrifugation, the water phase was made to 25 % saturation with ammonium sulfate, the precipitate removed by centrifugation and the radioactivity measured in the supernatant containing most of the virus.…”

“…Ryegrass streak virus appears to be a strain of bromegrass mosaic virus (Proll and Richter, 1965). It has been transmitted to Phleum species (Ohmann-Kreutzberg, 1963), but in contrast to PMV has a more extensive host range, produces local lesions in Datura stramonium and Chenopodium quinoa, and has been transmitted by nematodes of the genus Xiphinema (Proll and Schmidt, 1964). PMV also appears to differ serologically from cocksfoot mottle and ryegrass streak viruses (Serjeant, 1966).…”

SUMMARY A hitherto unrecorded virus having almost spherical particles about 30 nm in diameter was isolated from Phleum pratense and P. bertolonii. It was transmitted to five other species of Phleum, Agrostis nebulosa, Apera spica‐venti and Polypogon maritimus by sap inoculation. The virus was also transmitted by two species of beetle, Lema melanopa and L. lichenis. Some beetles became infective after short feeds on infected plants; others after long feeds. The virus sometimes persisted in the beetles for several days, but sometimes only for a few hours. Several beetles were already infective when caught in the field.
