Banana streak OL virus

Family   : Caulimoviridae
Genus    : Badnavirus
Acronym  : BSOLV

Introduction

Banana streak disease is caused by collection of Banana streak virus species. The only known hosts of BSVs are within the family Musaceae, and the virus probably occurs wherever bananas are cultivated. BSVs are a limiting factor in the development of new Musa hybrids by breeding programs across the world. Of the different BSV species, Banana streak OL virus (BSOLV) is commonly seen in India and other parts of the world. Symptoms of the disease vary widely and are influenced by the cultivar, virus species and environmental conditions.

Major Diseases

Banana streak disease

Geographical Distribution

Distribution throughout the banana cultivated regions in India.

Particle Morphology

BSV has bacilliform-shaped particles, 30 x 130-150 nm in size.

Transmission Method

The virus is transmitted to banana in a semi persistent manner by mealy bug, of which Planococcus citri is the most prevalent. The primary spread of the virus is through suckers or by mass-micropropagation of diseased suckers.

Detection

Polymerase chain reaction (PCR) , Reverse transcriptase PCR (RT-PCR) , non-radioactive probe-based nucleic acid spot hybridisation (NASH) and enzyme-linked immune-sorbent assay (ELISA) , Immuno Capture PCR and Rolling circle Amplification.

Host

Symptoms

Musa spp

Symptoms observed in field were ranging from chlorotic spots to chlorotic flecking spindle shaped chlorotic lesions and chlorotic mosaic. discontinuous chlorotic bands, mild chlorosis, stunted growth and inward rolling of leaf blade were predominant in diseased plants. yellow botches, brown yellow streaks, deformation, narrow strips and in severe cases at young stag cigar leaf necrosis, black/brown necrotic strips and internal necrosis of pseudo stem were recorded.
