Mesta yellow vein mosaic Bahraich virus

Family   : Geminiviridae
Genus    : Begomovirus
Acronym  : MeYVMBV

Introduction

Yellow vein mosaic disease of mesta (Hibiscus spp.) poses a serious threat to the cultivation of this crop in India. The disease was found to be associated with two different whitefly-transmitted monopartite begomoviruses, Mesta yellow vein mosaic virus and Mesta yellow vein mosaic Bahraich virus, together with two betasatellite species, Cotton leaf curl Multan betasatellite and Ludwigia leaf distortion betasatellite. These begomovirus complexes were detected in different combinations throughout the mesta growing regions of India. In eastern India, MeYVMD is associated with a recently described begomovirus, Mesta yellow vein mosaic virus (MeYVMV), and an isolate of Cotton leaf curl Multan betasatellite (CLCuMB). Symptomatic samples obtained from northern India showed the association of another recently described species of begomovirus, Mesta yellow vein mosaic Bahraich virus (MeYVMBV) and an isolate of Ludwigia leaf distortion betasatellite (LuLDB). These begomovirus complexes have been shown to be transmitted efficiently by a whitefly (Bemisia tabaci) and they have a very narrow host range.

Major Diseases

Yellow vein mosaic disease

Geographical Distribution

Northern India

Particle Morphology

Geminate particles

Transmission Method

By whitefly, Bemisia tabaci

PCR, rolling circle amplification

Host Range and Symptomatology ShowHide

Host	Symptoms
Hibiscus cannabinus (kenaf) and Hibiscus sabdariffa (roselle)	Yellowing of leaf veins followed by complete chlorosis of the leaves; height of diseased plants is reduced significantly and thus adversely affects the bast fibre yield.
