Rice yellow mottle, a mechanically transmissible virus disease of Rice in Kenya.
TLDR
In Kenya around Lake Victoria rice is affected by a hitherto undescribed virus for which the name Rice Yellow Mottle Virus (RYMV) is proposed, which is stable and highly infective.Abstract:
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 toOryza barthii andOryza punctata, but not toOryza eichingeri, barley, bulrush millet, durum wheat, finger millet, maize, oats, rye, sorghum, wheat, sugarcane, 20 other monocotyledonous and 9 dicotyledonous plant species.read more

The Genetic Basis of High Resistance to Rice Yellow Mottle Virus (RYMV) in Cultivars of Two Cultivated Rice Species.
TL;DR: Evaluation of F1 hybrids and interspecific progenies, as well as the segregation of resistance in F2 and F3 lines of the IR64 × Gigante cross, provided results consistent with the presence of a single recessive resistance gene common to Tog5681 and Gigante.

Rice yellow mottle virus (RYMV) in Africa: evolution, distribution, economic significance on sustainable rice production and management strategies.
TL;DR: Rice Yellow Mottle Virus (RMWV) is specific to Africa and was first noticed in Kenya, East Africa in 1966 as mentioned in this paper, it is said to have come to the foreground with the introductions of exotic rice (Oryza sativa L.) from Asia into the continent.

Distribution and Characterization of Rice yellow mottle virus: A Threat to African Farmers.
TL;DR: The disease’s impact on rice production in Africa, its distribution, symptomatology, and epidemiology, the physical and genetic characteristics of the virus, and resistance mechanisms and breeding efforts for resistance will be discussed.

Rice virus diseases
TL;DR: Rice virus diseases in this publication refer to rice diseases caused by viruses or by presumptive mycoplasma, which are caused by pathogenic agents which are infectious and multiply in host plants but do not belong to bacteria.

Movement of Rice Yellow Mottle Virus between Xylem Cells through Pit Membranes
Natacha Opalka,Christophe Brugidou,Caroline Bonneau,Michel Nicole,Roger N. Beachy,Mark Yeager,Claude M. Fauquet +6 more
TL;DR: It is proposed that the partial digestion of pit membranes resulting from programmed cell death may permit virus migration through them, concomitant with autolysis, and displacement of the Ca2+ from pit membranes to virus particles may contribute to the disruption of the pit membranes and facilitate systemic virus transport.

The transmission by mites, host-range and properties of ryegrass mosaic virus.
TL;DR: A virus that causes chlorotic streaks on ryegrass leaves was transmitted by the eriophyid mite Abacarus hystrix (Nalepa) by manual inoculation of sap to other species of Gramineae, including oats, rice, cocksfoot and meadow fescue, but none of these hosts seemed to contain as much virus as ryEGrass.

TL;DR: Outlines of techniques for using common methods such as host range studies, symptomatology, physical properties tests, cross-protection tests and insect transmission data, and suggestions are given for the use of some of the newer approaches including physicochemical property studies, serology, and electron microscopy.

Some properties of cocksfoot mottle virus
TL;DR: Cocksfoot mottle virus (CFMV) was transmitted by manual inoculation of sap to cocksfoot (Dactylis glomerata L.), wheat, oats and barley, but not to nineteen other monocotyledonous and thirteen dicotylingonous plant species.
