Rice necrosis mosaic virus

Family   : potyviridae
Genus    : Bymovirus
Acronym  : RNMV

Introduction

Rice necrosis mosaic virus infects rice plants causing mosaic symptoms characterized by reduction of growth, chlorotic streaks and flecks on the leafs, necrotic spots on the leaves, leaf sheath and culms. In infected plants leaf area is reduced, tillers are decreased in number and the growth habit becomes some what prostrate and spreading. In infected Ludwiga perennis the virus is reported to increase leaf size and plant height along with characteristics symptoms.

Major Diseases

Yellow Flecks and Streaks Disease/Mosaic Disease

Geographical Distribution

Andhra Pradesh, Gujarat, Punjab, Rajasthan and West Bengal.

Particle Morphology

Rod shaped particles having two model length (275 and 550 nm) and width varying from 13-14 nm.

Transmission Method

Transmitted by a vector; a fungus; Polymyxa graminis; Plasmodiophorales. Virus transmitted by mechanical inoculation.

Detection

ELSA

Host Range and Symptomatology

Oryza sativa L (rice) Mosaic, chlorotic streaks and flecks on leaves, leaf sheath and culms.
