“…These results agree with those reported by Kawano et al (1983), which were considered to describe the complete particle of RRSV (Milne, 1980). So far, no particles with outer shells like those of Fijiviruses (Milne & Lovisolo, 1977) have been observed in preparations of RRSV, and the core particles with spikes seem to represent RRSV particles, although there is a possibility that the intact virion has an outer shell which is removed during purification or staining. Particles pelleted in MgCI2 solutions less concentrated than 0.1 M appeared to be almost the same as the untreated particles.…”

“…Treatment of particles with organic solvents removes the outer capsids of Fijivirus subgroup viruses but not those of viruses in the Phytoreovirus subgroup (Milne & Lovisolo, 1977;Omura et al, 1982). As was shown by Reddy & Macleod (1976) for WTV and by Nakata et al (1978) for RDV, the outer capsid of RGDV was removed by CsCI treatment at an appropriate pH.…”

SUMMARYProtein from particles of rice gall dwarf virus was resolved into seven components by polyacrylamide gel electrophoresis. The estimated molecular weights ( × 103) were 183, 165, 150, 143, 120, 56 and 45 (K). Cores prepared by treating intact particles with CsC1 contained the 183K, 165K, 120K and 56K proteins: the 150K, 143K and 45K proteins were recovered from the top layer of gradients after CsC1 equilibrium centrifugation. Antiserum against intact particles reacted mainly with 150K and 45K proteins and antiserum against core particles reacted mainly with 183K and 120K proteins. The results suggest that the 150K and 45K proteins are located on the surface of the outer capsid, that the 183K and 120K proteins are on the surface of the core, that the 165K and 56K proteins are inside the core, and that the 143K protein is either inside the outer capsid or inside the core.

“…Delphacodes kuscheli Fennah, "chicharrita" perteneciente al orden Hemiptera, familia Delphacidae es el principal vector del MRCV (Remes Lenicov et al, 1985;Ornaghi et al, 1993;. La modalidad de transmisión de los Fijivirus es persistente propagativa (una vez adquirido, el virus se multiplica dentro del cuerpo del vector, el cual permanece infectivo durante toda su vida) (Milne & Lovisolo, 1977;Arneodo, 2002a).Respecto a los hospedantes naturales del MRCV, éstos pertenecen casi en su totalidad a la familia Poaceae; algunos de ellos son cultivos anuales invernales como avena y trigo (Rodríguez Pardina et al, 1998) los que, además de ser reservorios del virus, resultan propicios para la cría, alimentación y oviposición de la chicharrita que lo transmite, que luego migra hacia plantas de maíz en sus primeros estadios de crecimiento. De este modo, el trigo constituye un importante eslabón en la cadena epidemiológica de la enfermedad (Remes Lenicov et al, 1985;Teson et al, 1986;Ornaghi et al, 1993).…”

RESUMENMal de Río Cuarto virus en trigo provoca una enfermedad resultante de la acción combinada con su principal vector, Delphacodes kuscheli. La severa sintomatología inducida por virus e insecto condujo a determinar la posible existencia de alteraciones fisiológicas en inducida por virus e insecto condujo a determinar la posible existencia de alteraciones fisiológicas en el cultivar de trigo ProINTA Federal, infectado artificialmente con dos aislamientos geográficamente distantes del MRCV y sometido a picadura de insectos no virulíferos, respectivamente, en tres estadios fenológicos. ProINTA Federal fue picado por insectos no virulíferos e inoculado en la primera hoja emergiendo del coleóptilo, en la cuarta y quinta hojas desplegadas, respectivamente. La condición sanitaria de los diferentes tratamientos fue constatada mediante ELISA. Las plantas tratadas manifestaron alteraciones fisiológicas con similares variaciones entre estadios fenológicos. Azúcares solubles totales, almidón y proteínas solubles incrementaron significativamente su contenido en plantas infectadas por MRCV. En plantas PS y con MRCV, el contenido de clorofilas disminuyó marcadamente y lo inverso sucedió con el malondialdehído, lo que indicaría daño oxidativo por estrés en las mismas. No existieron diferencias entre estadios fenológicos y las variaciones de los indicadores de alteraciones fisiológicas considerados, excepto para el incremento de almidón, significativamente superior en plantas inoculadas en la primera hoja emergiendo del coleóptilo. Palabras clave: infección viral, toxicidad por insectos, azúcares solubles, almidón, proteínas, clorofilas, malondialdehído, estadios fenológicos. ABSTRACT Physiological alterations associated to the Mal de Rio Cuarto virus (MRCV) infection and to vector (Delphacodes kuscheli Fennah) phytotoxicity in wheatMal de Río Cuarto virus produces a wheat disease, resulting from the combined action of this pathogen and its main vector, resulting from the combined action of this pathogen and its main vector, from the combined action of this pathogen and its main vector, of this pathogen and its main vector, this pathogen and its main vector, Delphacodes kuscheli. Knowing that viruses and insects cause a severe symptomatology in different genotypes, the objective of this nowing that viruses and insects cause a severe symptomatology in different genotypes, the objective of this severe symptomatology in different genotypes, the objective of this in different genotypes, the objective of this genotypes, the objective of this the objective of this the objective of this of this work was to determine the possible physiological alterations in three phenological stages of wheat (cv ProINTA Federal) inoculated by was to determine the possible physiological alterations in three phenological stages of wheat (cv ProINTA Federal) inoculated by possible physiological alterations in three phenological stages of wheat (cv ProINTA Federal) inoculated by le physiological alterations in three phenological stages of wheat (cv Pro...
