Un virus aislado de semilla de papa importada, cv. Sieglinde, lúe caracterizado como la cepa Bouquet de la papa, perteneciente al virus del anillo negro del tomate, un trepo-virus. El virus fue identificado por medio de plantas hospederas, propiedades físicas, morfología de partículas 32 ensayos serológicos. La introducción de esta enfermedad en Brasil y su posible subsecuente expansión, es discutida debido a que el país importa semilla de papa y, a que la presencia de nematodos del género Longidorus, vector natural de algunos nepovirus, ha sido descrita en varias regiones de Brasil.
A virus isolated from imported seed potato, cv. Sieglinde, was characterized as potato Bouquet strain, belonging to the tomato black ring virus, a trepo-virus. The virus was identified by means of host plants, physical properties, particle morphology and serological assays. The introduction of this disease in Brazil and its possible subsequent spread is discussed because the country imports potato seed and the presence of nematodes of the genus Longidorus, natural vector of some nepoviruses, has been described in several regions of Brazil.
