The effect of prunus necrotic ringspot virus on field‐grown roses
Annals of Applied Biology, 1982SUMMARYThe effect of prunus necrotic ringspot virus (PNRSV; cherry serotype) on field‐grown maiden rose bushes cv. Fragrant Cloud was assessed in two trials during 1979 and 1980. PNRSV delayed the onset of flowering, reduced the size and number of blooms and increased the proportion of deformed flowers but had no effect on flower pigmentation or scent.

Molecular characterization of two prunus necrotic ringspot virus isolates from Canada
Archives of Virology, 2012We determined the entire RNA1, 2 and 3 sequences of two prunus necrotic ringspot virus (PNRSV) isolates, Chr3 from cherry and Pch12 from peach, obtained from an orchard in the Niagara Fruit Belt, Canada. The RNA1, 2 and 3 of the two isolates share nucleotide sequence identities of 98.6%, 98.4% and 94.5%, respectively.

In Vitro Elimination of Prunus Necrotic Ringspot Virus in a Plum Cultivar
1999Production of vegetatively propagated plant material is based on building up stocks from source plants. Viruses entering a propagation system at the breeding or germ plasm level are transmitted vertically down the propagation chain. The ultimate outcome of this process is virus-infected planting material.

Improved detection of prunus necrotic ringspot virus by the polymerase chain reaction
European Journal of Plant Pathology, 1996The reverse transcription — polymerase chain reaction (RT-PCR) technique was used for detection of prunus necrotic ringspot virus in dormant peach trees which tested negative by ELISA. Total RNA extracted from bark tissue, using a lithium chloride based method, were used for reverse transcription and subsequent amplification of viral sequences. The PCR

Prunus necrotic ringspot virus (PNRSV) was detected by PCR in Tunisian stone fruit germplasm collections. Peach had the highest infection rate reaching 50%, followed by apricot (46.8%), almond (35.5%) and plum (9.5%). The genetic variability of the CP gene of 10 PNRSV isolates was evaluated by SSCP analysis of PCR products and analysis of their ...

FIRST REPORT OF PRUNUS NECROTIC RINGSPOT VIRUS INFECTING BINDWEED IN IRAN
Journal of Plant Pathology, 2013Prunus necrotic ringspot virus (PNRSV) affects rosaceous plants worldwide. In 2011 and 2012, 50 symptomatic bindweeds (Convolvulus arvensis) were collected from rose gardens in Alburz, Mazandaran and Tehran provinces of Iran. Samples were tested for the presence of PNRSV using DAS-ELISA and dot-immunobinding assay (DIBA) with a polyclonal antiserum ...

Transmission of prunus necrotic ringspot virus using plum pollen and thrips
Annals of Applied Biology, 1991SUMMARYPrunus necrotic ringspot virus (PNRSV) was transmitted to cucumber but not to peach seedlings after they were dusted with infective plum pollen and caged with 8–10 thrips per seedling for 24 h. When the pollen was taken from three plum trees shown by mechanical inoculation tests to have highly infective flower buds and pollen, the transmission ...

Oxidative stress induction by Prunus necrotic ringspot virus infection in apricot seeds
Physiologia Plantarum, 2007Prunus necrotic ringspot rvirus (PNRSV) was able to invade the immature apricot seed including the embryo. The amount of virus was very high inside the embryo compared with that present in the cotyledons. PNRSV infection produced an oxidative stress in apricot seeds as indicated by the increase in lipid peroxidation, measured as thiobarbituric acid ...

FIRST REPORT OF PRUNUS NECROTIC RINGSPOT VIRUS ON NECTARINE FROM IRAN
Journal of Plant Pathology, 2016Prunus necrotic ringspot virus (PNRSV, Genus Ilarvirus, Family Bromoviridae) is pollen and seed transmitted and this contributes to its spread in stone-fruit trees. In 2015, 18 leaf samples from nectarine (Prunus persica var. nucipersica) symptomatic trees were collected from East-Azerbaijan and Zanjan provinces in west and north-west of Iran.

Summary Prunus necrotic ringspot virus (PNRV) proved as seed-transmissible in apricot (Prunus armeniaca L.), but to a low extent only. Progenies from seeds of a naturally infected open pollinated apricot tree were PNRV-infected by 1.1%. PNRV-infected apricot seedlings up to two leaf stage showed neither growth depression nor other disease symptoms.
