Banana streak Mysore virus

Family   : Caulimoviridae
Genus    : Badnavirus
Acronym  : BSMYV

Introduction

Banana streak disease of bananas and plantains worldwide is caused by a collection of Banana streak virus (BSV) species. Symptoms of streak disease vary widely and are influenced by the cultivar, virus species, and environmental conditions. The typical symptoms include narrow, discontinuous chlorotic, and/or necrotic streaks that run parallel to the veins of the leaf lamina, and pseudostem splitting. In a few cases, internal necrosis, aberrant bunch emergence, fruit peel splitting, and necrotic fruit spots are also seen. Symptoms can reappear with periods of symptomless growth, temperature being considered as a factor in disease expression. Symptoms and virus load depend strongly on temperature
