Shallot latent virus

Family   : Betaflexiviridae
Genus : Carlavirus
Acronym : SLV

Introduction

Shallot latent virus is now a recognized virus name for Garlic latent virus infecting garlic. SLV is an aphid born Carlavirus and infects plant systemically without eliciting any symptoms or significant loss but when present with a potyvirus such as Onion yellow dwarf virus the damage is severe and synergetic.

Major Diseases

Mosaic/Chlorosis

Geographical Distribution

South India and Delhi.

Particle Morphology

Flexuous particles of 610-700 x 12 nm.

Transmission Method

Aphis craccivora and Myzus persicae transmitted the virus in a non-persistent manner; also transmitted by mechanical inoculation.

Detection

ELISA and RT-PCR.

Host Range and Symptomatology

Allium sativum (Garlic) Mosaic and chlorotic symptoms.
Allium porrum (Leek)Mild chlorotic streaking.
