Biology and molecular characterization of necroviruses
Félix, M. Rosário; Varanda, Carla M.R.; Clara, M. Ivone E.Three necroviruses, family Tombusviridae, are known to infect Olea europaea L., Olive latent virus 1 (OLV-1), Olive mild mosaic virus (OMMV) and Tobacco necrosis virus D (TNV-D), often asymptomatically. OLV-1 has a wide geographical distribution whereas that of OMMVand TNV-D is not known as their discovery is recent, dating from 2005 and 2009, respectively. OMMV has received special attention because of its ori...
Biological and Molecular Characterization of Olive latent virus 1
Félix, M. Rosário; Cardoso, Joana M.S.; Oliveira, Solange; Clara, M. Ivone E.Olive latent virus 1 (OLV-1) belongs to the Necrovirus genus, Tombusviridae family and is pathogenic to olive, citrus and tulip plants. It is easily mechanically transmissible to indicator plants causing necrotic lesions and can be transmitted through the soil into the plant roots in the absence of biological vectors. Infected cells contain virus aggregates, inclusions made up of excess of viral coded peptides ...

The complete genome sequence of a new necrovirus isolated from Olea europaea L.
Cardoso, Joana M.S.; Félix, M.Rosário; Clara, M. Ivone E.; Oliveira, SolangeAbstract: The complete nucleotide sequence of a virus isolated from Olea europaea L. (GP isolate), previously identified as an isolate of Tobacco necrosis virus D (TNV-D) based on its coat protein sequence, was determined. The viral RNA genome consists of 3683 nucleotides and contains five open reading frames. The putative RNA-dependent RNA polymerase shows 91.2% amino acid identity with that of an isolate of O...
Complete nucleotide sequence of an Olive latent virus 1 isolate from olive trees
Félix, M. Rosário; Cardoso, Joana M.S.; Varanda, Carla M.R.; Oliveira, Solange; Clara, M. Ivone E.Olive latent virus 1 (OLV-1) is a necrovirus belonging to the familyTombusviridae. It is a small icosahedral plant virus, which encapsidates a single stranded positivesense RNA. This virus was first isolated from symptomless olive trees in Italy [7] and afterwards in Jordan and Portugal [10, 4]. OLV-1 was also isolated from symptomatic hosts, such as citrus trees in Turkey [11] and tulips in Japan [9]. Up to no...
