Tobacco leaf curl Pusa virus

Family   : Geminiviridae
Genus    : Begomovirus
Acronym  : TbLCPuV

Introduction

Tobacco leaf curl disease has been known for a century. It is known to cause serious losses in tobacco production over 75 years. So far 11 distinct monopartite and one bipartite begomoviruses have been identified to cause leaf curl diseases of tobacco in various parts of the world. Tobacco cabbaging virus, Tobacco curly leaf virus, Tobacco frenching virus, Tobacco leaf curl virus 1, Tomato yellow dwarf virus are few strains reported.

Major Diseases

Leaf curling and stunting

Geographical Distribution

Wide spread in tobacco growing regions.

Particle Morphology

Geminate particles measuring 15-20 x 25-30 nm.

Transmission Method

Transmitted by a vector; an insect; Bemisia tabaci; Aleyrodidae in a persistent manner, transmitted by mechanical inoculation; not transmitted by seed.

Detection

ELISA, PCR and rolling circle amplification.
