First report of Prunus necrotic ringspot virus on nectarine from Iran.


Prunus 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, a total of 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. Trees showed stunting, and exhibited chlorotic rings, mosaic and necrotic ringspots on leaves. Based on sequence comparison and phylogenetic analysis, the causal agent was identified as PNRSV. This is thought to be the first report of PNRSV on nectarine from Iran.
