Prunus necrotic ringspot virus

Family   : Bromoviridae
Genus    : Ilarvirus
Acronym  : PNRSV

Introduction

Prunus necrotic ringspot virus (PNRSV) is a plant pathogenic virus which attack cherry trees. The virus has a fairly wide host range among dicotyledonous plants.

Major Diseases

Mosaic disease/necrotic ringspot disease

Geographical Distribution

Himachal Pradesh, Jammu and Kashmir, Uttarakhand and North eastern states.

Particle Morphology

An RNA-containing virus with isometric particles about 23-27 nm in diameter.

Transmission Method

The causal agent was mechanically transmissible; Transmitted by Several aphid species (Myzus persicae, Aphis gossypii, A. fabae-solanella, Brevicoryne brassicae and Macrosiphoniella sanbornii) failed to transmit the virus.transmitted by grafting; not transmitted by contact between plants; transmitted by seed.

Detection

ELISA and RT-PCR.
