Southern bean mosaic virus

Family   : unassigned
Genus    : Sobamovirus
Acronym  : SBMV

Introduction

SBMV is a sobemovirus that causes mosaic and mottle diseases in common bean. The virus is characterized by isometric particles (30 nm), which encapsidate a single-stranded positive-sense genomic RNA of approximately 4100 nucleotides.

Major Diseases

Mosaic and mottle.

Geographical Distribution

Widespread

Particle Morphology

Isometric particles about 30 nm in diameter

Transmission Method

Transmitted by leaf beetle (Madurasia obscurella) in a non-circulative manner and also through seeds.

Detection

ELISA and RT-PCR.

Host Range and Symptomatology

French bean, Urdbean and CowpeaGreen mosaic, chlorotic patches in young and old leaves and leaves are greener than healthy ones.
