Abstract

The complete genome sequence of a Southern tomato virus (STV) isolate on tomato plants in a seed production field in Bangladesh was obtained for the first time using next-generation sequencing. The identified isolate, STV_BD-13, shares a high degree of sequence identity (99%) with several known STV isolates worldwide.

Highlights

  • The complete genome sequence of a Southern tomato virus (STV) isolate on tomato plants in a seed production field in Bangladesh was obtained for the first time using next-generation sequencing

  • Based on its double-stranded RNA (dsRNA) genome and the pattern of genome structure, STV was classified in the genus Amalgavirus of the family Amalgaviridae (1)

  • STV has been regarded as a causal agent of disease in tomato (1)

Summary

Introduction

The complete genome sequence of a Southern tomato virus (STV) isolate on tomato plants in a seed production field in Bangladesh was obtained for the first time using next-generation sequencing. Southern tomato virus (STV) is a double-stranded RNA (dsRNA) virus with a small genome of approximately 3.5 kb containing two overlapping open reading frames (ORFs). STV has been regarded as a causal agent of disease in tomato (1). Since its first discovery on tomato plants in Mexico and the United States (1), STV has been identified in France (2), Spain (3), and most recently in China (4).
