Cherry necrotic rusty mottle virus

Family   : Betaflexiviridae
Genus    : Robigovirus
Acronym  : CNRMV

Introduction

Cherry necrotic rusty mottle virus (CNRMV) belongs to the genus, Robigovirus causing reduced growth, significant yield loss and early death. The disease symptoms (necrotic rusty mottle and rusty mottle) on the leaf of diseased plants can be highly variable and depends upon climatic conditions, virus isolates and plant cultivar. It also infects Himalayan wild cherry and bamboo (Dendrocalamus hamiltonii). The genome of CNRMV is monopartite and consists of single-stranded positive-sense RNA having 7 open reading frames (ORFs). Major Disease: Necrotic rusty mottle disease

Geographical Distribution

Himachal Pradesh, Jammu and Kashmir

Particle Morphology

Flexuous rod shaped particles of 580 x 11 nm

Transmission Method

Through graft.

Detection

ELISA, RT-PCR and IC-RT-PCR

Host Range and Symptomatology

Host	Symptoms
Cherry	Reduced growth, significant yield loss and early death
Himalayan 'maggar' bamboo (Dendrocalamus hamiltonii)	Marginal chlorosis, mosaic, shot holes and necrotic spots on leaves
